absorption trap General usage: Absorption of noxious acid fumes and gasses without mechanical fume extraction. It is usually used in conjunction with Kjeldahl digestions and Friedel-Craft reactions Material: Boro-silicate glass Features: An apparatus consisting of a bulb trap on top of which is fitted a cylinder comprising of a porosity 1 sintered disc, a drip tube and ground cones and sockets on each component Modifications: Alternate socket and cone sizes Operation: The assembled trap is fitted onto a Kjeldahl flask and the bulb is half filled with a 10% sodium hydroxide solution. Fumes that are evolved force the solution into the cylinder until the level drops below the drip tube in the bulb. Fumes then pass up through the sintered disc which assists absorption by fine division of the bubbles Blocked pores of the sintered disc could cause the apparatus to blow apart CAPACITY ml 250 JOINTS B24 CATALOGUE # 24068365 acid bottles General usage: Storage of acids and other corrosive liquids Material: Soda-lime glass Features: A bottle with a ground socket neck and penny-head stopper A ground in cap fits over the neck to give added protection against leakage of fumes CAPACITY ml 500 1000 CATALOGUE # 052127544 052127554 552 adapters - apparatus joint manipulation General usage: Connecting dissimilar sized ground joints in apparatus assemblies Material: Boro-silicate glass Modifications: Addition of spring hooks Accessories: ● Keck clip for clamping the joints ● High vacuum grease ● Holding springs CONICAL/SPHERICAL ADAPTERS Specific usage: Connecting conical and spherical joints Features: ● The cone/cup adapter has a cup at the top and cone at the bottom ● The socket/ball adapter has a socket at the top and ball at the bottom CODE CC3/35 SB3/35 CONICAL JOINTS B24 cone B24 socket SPHERICAL JOINTS S35 cup S35 ball CATALOGUE # 242065 242075 EXPANSION AND REDUCTION CONICAL ADAPTERS Specific usage: ● Expand from socket to cone ● Reduce from socket to cone Features: ● The expansion adapter has a large socket at the top and small cone at the bottom ● The reduction adapter has a small socket at the top and large cone at the bottom CODE JOINTS cone to socket B10 to B14 B14 to B19 B14 to B24 B14 to B29 B19 to B24 B19 to B29 B19 to B34 B24 to B29 B24 to B34 B29 to B24 B29 to B34 B29 to B40 B29 to B45 XA10 XA21 XA31 XA41 XA32 XA42 XA52 XA43 XA53 XA54 XA64 XA74 CATALOGUE # CODE 2420831 2420843 2420853 2420863 2420854 2420864 2420874 2420865 2420875 2420876 2420884 2420886 2420896 DA01 DA12 DA13 DA14 DA23 DA24 DA34 DA25 DA35 DA45 DA48 JOINTS cone to socket B14 to B10 B19 to B14 B24 to B14 B29 to B14 B24 to B10 B24 to B19 B29 to B19 B29 to B24 B34 to B19 B34 to B24 B34 to B29 B50 to B29 CATALOGUE # 2420913 2420934 2420935 2420936 2420941 2420945 5420946 2420956 2420947 2420957 2420967 2420960 adapters - flexible joint manipulation Usage: Joining misaligned conical joints in apparatus assemblies Material: PTFE Features: Bellows tube with a cone on one end and a socket on the other end JOINTS B24 B29 B34 CATALOGUE # 1K1047 1K1048 1K1049 553 adapters - multiple connection General usage: Multiple connection of ground joints in apparatus assemblies Material: Boro-silicate glass Modifications: Addition of spring hooks Accessories: ● Keck clip for clamping the joints ● High vacuum grease ● Holding springs Features: ● ● ● ● TYPE 2 necks parallel CODE MA1/00 MA1/11 MA1/2 MA1/3 MA1/33 MA1/44 MA2/2 MA2/3 RA4/11 RA4/22 RA4/23 MA4/23 - 2 necks, 1 at 450 2 necks, 1 at 150 3 necks, 1 at 450 The The The The adapter adapter adapter adapter with with with with parallel necks has two sockets at the top and a cone at the bottom two necks, one at 45 º, has two sockets at the top and a cone at the bottom two necks, one at 15 º, has two sockets at the top and a cone, with a drip-tip, at the bottom three necks has two vertical and one at 45 º with sockets at the top and a cone at the bottom JOINTS B10 B14 B19 B19/B24 B19/B29 B24 B24/B29 B29 B19 B19/B24 B14 B19 B19/B24 B24/B29 B24 B29 CATALOGUE # 2422411 2422433 2422444 2422445 2422446 2422455 2422456 2422466 2422544 2422545 2422633 2422644 2422645 2422656 2422744 2422755 2422766 adapters - pourers General usage: Facilitate pouring from ground neck bottles and flasks Material: Boro-silicate glass Features: Ground cone fitted with a pouring spout Modifications: Addition of hooks to hold springs Accessories: ● Keck clip for clamping the joints ● High vacuum grease ● Holding springs NECK mm B14 B19 B24 B29 CATALOGUE # 240003 240004 240005 240006 554 adapters - receivers General usage: Directing delivery and distribution of end product from reactions in apparatus assemblies Material: Boro-silicate glass Modifications: Addition of hooks to hold springs Accessories: ● Keck clip for clamping the joints ● High vacuum grease ● Holding springs VERTICAL DELIVERY TUBE Specific usage: In conjunction with a distribution chamber to avoid having to interrupt a reaction when a receiving vessel becomes full Features: A socket with a cone underneath and a sideways drip tip BENDS Specific usage: Usually at the delivery end of a condenser used angled in an assembly for distributing into a flask.

Vacuum tubing is attached to the tubing olive or connection. A vacuum is then created in the flask by sucking air from the flask using a water jet pump or vacuum pump. Filtration is accelerated by the suction created inside the flask. A tubulature, screwthread tubing connector or a Keck tubing connector assembly is recommended 565 buchner funnels General usage: Vacuum filtration, generally with a Buchner flask Material: Porcelain, polypropylene, boro-silicate glass Features: Conical shape with a perforated base.

COLD SOLUTIONS When substantial quantities of a solid are to be filtered from suspension in a liquid, a Buchner funnel of convenient size is employed. Suction causes rapid filtration and results in a more complete removal of the base liquid than in normal atmospheric filtration. Select a filter paper of such size that it covers the entire perforated plate without being folded up against the sides of the funnel (it should be slightly smaller than the plate). Moisten the filter paper with the liquid to be filtered, place it on the perforated plate and apply the suction. The filter paper will adhere firmly to, and completely cover, the plate of the funnel thereby preventing any solid matter from passing underneath the filter paper and into the flask. Pour as much of the liquid into the funnel and allow it to be filtered before transferring the residual slurry into the funnel for filtration. This method allows quicker filtration than if the mixture had been stirred to bring more particles into suspension and pouring it directly unto the funnel. Initial gentle suction leads to more effective filtration than powerful suction which could cause finer particles of solid to be drawn into the pores of the filter paper reducing the rate of filtration. After completion of a reaction, filtration of a mixture will often be necessary to either isolate a solid which has separated out or remove insoluble impurities or reactants, in which case the desired material remains in solution. Any solid remaining in the reaction flask can be easily transferred to the filter funnel by rinsing with a bit of the filtrate and stirring well to remove any solids adhering to the sides of the reaction flask. Be sure to disconnect the pump from the Buchner flask before switching off the pump otherwise suck back will occur and ruin any reaction products in the filtrate. HOT SOLUTIONS Pre-heat the Buchner funnel and use a close-grained, or glass microfibre, filter paper. 566 burettes General usage: Measured and accurate titration of liquids Material: Boro-silicate glass Specifications: Class A.

An ignited crucible or other very hot object should be cooled for about one minute before being placed into the desiccator on a perforated plate. In either case, the lid of the desiccator should be slightly ajar for 30 seconds prior to complete closing. This will prevent a partial vacuum from forming as the heated air cools. If such a vacuum forms it might become very difficult to remove the lid without upsetting the samples within. A dried sample should remain in the desiccator for at least 5 minutes before being weighed. If the sample is to remain in the desiccator for an extended period of time before weighing, the top of the weighing bottle of the lid of the vial should be put in place after 10 minutes of cooling. An airtight seal is maintained by applying a small amount of silicone grease to the flanged surfaces where the lid and body of the desiccator meet. Once the desiccant has been added, the lid to the desiccator should not be removed any more than is necessary Drying agents should not be placed directly in the desiccator but rather in a crystalising dish SIZE mm 100 150 200 250 300 SPARE STOPCOCKS PLATE mm 90 140 190 240 280 Straight shank glass key Straight shank PTFE key B24 cone glass key B24 cone PTFE key B24 spindle valve SODA-LIME GLASS PLAIN CATALOGUE # 05596111 05596112 05596113 05596114 05596115 VACUUM CATALOGUE # 05596311 05596312 05596313 05596314 05596315 BORO-SILICATE GLASS PLAIN CATALOGUE # 2478146 2478157 2478161 2478166 2478169 VACUUM CATALOGUE # 2478246 2478257 2478261 2478266 2478269 24149G 24149T 241495G 241495T 2479904 590 desiccators - plastic Alternate names: Drying chamber General usage: Cooling of heated substances and for the storage of dry substances that must not be exposed to the moisture normally present in the atmosphere Material: Polycarbonate and polypropylene Features: ● ● ● ● Base with flat flange Lid with matching flat flange PTFE stopcock in the lid of the vacuum desiccator Polypropylene perforated desiccator plate Accessories: ● ● ● ● Crystalising dish to hold desiccant High vacuum grease for sealing the lid to the base Desiccant Suggested: silica gel orange, anhydrous calcium chloride, phosphorous pentoxide Operation: See previous page LARGE INTERIOR VOLUME -- The space saving design of the desiccator dome provides maximum interior clearances.

Precipitates that have to be dried to the constant weight Material: Boro-silicate glass Features: ● Flame polished rim ● Sintered disc with porosity of choice Operation: After cleaning, the filter crucible quickly reaches constant weight at 110ºC, as the remaining water evaporates. After the filtration it is placed with the moist precipitate in the hot drying cabinet at up to 150ºC where it is dried to the constant weight. Depending on the method of determination, it can be cooled by exposure to air or in a desiccator. To calcine a precipitate the crucible is placed in a cold oven and heated up to a maximum of 500ºC. After heating has been switched off it is allowed to cool down to about 200ºC in the oven Accessories: ● ● ● ● ● CAPACITY ml 10 10 10 10 10 15 15 15 15 15 30 30 30 30 30 50 50 50 50 50 60 60 60 60 60 POROSITY P0 P1 P2 P3 P4 P0 P1 P2 P3 P4 P0 P1 P2 P3 P4 P0 P1 P2 P3 P4 P0 P1 P2 P3 P4 ADAPTERS FOR CRUCIBLE ml 10 15 30 50 60 CATALOGUE # 2431608 2431609 2431615 2431617 2431619 Adapter Gloves Tongs Rubber sealing sleeve Hot grips DIAMETER mm 24 24 24 24 24 26 26 26 26 26 36 36 36 36 36 56 56 56 56 56 56 56 56 56 56 DISC DIAMETER mm 20 20 20 20 20 20 20 20 20 20 30 30 30 30 30 40 40 40 40 40 40 40 40 40 40 CATALOGUE # 2406008 2406108 2406208 2406308 2406408 2406009 2406109 2406209 2406309 2406409 2406012 2406112 2406212 2406312 2406412 2406017 2406117 2406217 2406317 2406417 2406019 2406119 2406219 2406319 2406419 603 filter crucibles - ceramic Alternate names: Gooch crucible General usage: Applications in quantitative analysis.

Magnetic stirring and mixing is used in a number of common laboratory procedures. The importance of selecting the best stirring bar for each particular application is often overlooked. Varying the size, shape or length of the magnetic stirring bar will after the motion imparted to the solution. Thus, selection of the appropriate stirring bar for given application should be done with great care. Understanding the principles of magnetism is important. On the most basic level, we are aware that opposite poles attract. However, we must also understand the significance of the drive element, magnetic coupling,” spin-out”, vessel shape, viscosity and turbulence. The drive motor of a magnetic stirrer provides the rotation necessary to spin the drive magnet. The drive magnet is generally a bar or “U-shaped” alloy or a ceramic disk. The magnetic poles are typically about 50mm apart in bench top models. The poles can be up to 140mm apart in units large enough to mix 190litres of liquid solution. For optimum efficiency and magnetic coupling, the distance between the magnetic poles of the drive magnetic poles of the drive magnet and the length of the stirring bar should be equal. Therefore, the drive magnet dictates the longest possible stirring bar that can be used effectively. A small metal washer moved around the surface plate of the stirrer will naturally gravitate towards one of the poles of the drive magnet. A small magnetic stirring bar will provide similar results. Another important parameter in choosing a magnetic stirring bar is the vertical distance between the drive magnet and stirring bar. The material and thickness of the cover plate as well as that of the containing vessel can also influence stirring efficiency. Cover plates are made of paramagnetic materials such as ceramic or aluminum, which offer better coupling of the drive magnet and stirring bar. The magnetic energy is not impeded as it might be if the top were made of magnetic materials. The amount of magnetic energy that joins the two magnets (coupling) falls off as the distance between them increase. Stated mathematically, “the coupling energy of force is inversely proportional to the square of the distance between them”. It stands to reason that for the best magnetic coupling, the distance between the magnets should be minimized. Magnetic stirring bars are generally made of ALNICO (an alloy of aluminum, nickel, iron and cobalt) encapsulated in an FDA approved PTFE coating. This combination offers the best compromise of magnetic strength, usefulness and cost. The PTFE coating is only useful at temperatures up to 225 °C . Other coatings or coverings such as glass tubing, polypropylene and polyethylene are also used. More exotic materials have not been found to be commercially viable. High energy materials, such as Samarium Cobalt and Neodymium Iron Boron, though having a much higher energy product (Bd x Hd) than ALNICO V, do not always work better as drive magnets. The geometry of the magnet, in the case of bar magnets, length/diameter (L/D), governs how effective the magnet will be. The aforementioned magnets have energy products of three to six tomes that of ALNICO V in geometry of 1 to 1. When used in a 4 to 1 configuration, their relative levels are nearly the same or less than the ALNICO V. Additionally, many of the exotic materials are extremely temperature sensitive and will demagnetize as the temperature increases. Once a magnetic stirring bar has been placed in a container with a solution, it should be positioned directly over the centre of the drive magnet. The stirring speed should be increased slowly, until the desired vortex pattern is achieved. Should the magnetic stirring bar lose its coupling with the drive magnet because of the speed of the drive magnet or the viscosity of the fluid, it is said t have “spun-out”. Improperly selected stirring bars are the frequent cause of “spin-out”, as well as a drive magnet speed that is too fast. Matching the drive and stirring magnet improves results dramatically.

A new range of NMR tubes has now been developed which caters for all the quality criteria for obtaining optimum spectra that were only conceivable before. What is so interesting about NMR tubes that it is worth writing about? Now all NMR users know how very much the quality of their spectra depend on the quality of the sample vessel they are using. There are initially two reasons for this: The sample tube is also measured as part of the measuring process. This means that its material and geometry properties should have preferably no influence on the measurement or at least an influence which can be eliminated by calculation. The sample vessel itself is in an inaccessible position in the measuring instrument during the measurement process, namely in the middle of the magnet. It should not be disturbed there under any circumstances since it is very difficult to interfere with it in this position. The material and dimensions of NMR tubes are subject, therefore, to very stringent requirements – and they are accordingly expensive to manufacture. Before a new range of NMR sample tubes comes on the market, a large number of tests have to be carried out before the products agree with the specifications laid down. Then, when they are in full production, measures have to be implemented to ensure that the specifications laid down are adhered to. NMR quality criteria The decisive factor for the quality of a spectrum is how accurately the magnetic field is adjusted to the sample in the NMR tube. As this adjustment (or shimming) can be a complicated process, both the absolute geometry of the tube and the comparability of different tubes are a important quality criteria. For this reason, the adjustments between the different tubes, e.g. in the sample changer, should be as identical as possible. Shimming is then only required once and not for each tube. From this the various quality criteria for a good NMR tube can be derived: Identical sample quantities should come to the same level in several tubes in the sample changer. Otherwise the magnetic field must be readjusted. ● All tubes should have the same diameter as far as possible. ● The wall thickness should be the same at every point. ● The tube must be straight. ● All the tubes must sit firmly in the spinner without moving and must be a good fit. ● The tubes should be robust so that they cannot be damaged in the NMR unit. ● The glass should be chemically resistant and inert to all samples. ● The glass may not contain any paramagnetic impurities that can result in problems in the spectrum. ● The tubes must be labeled so that different qualities can be clearly distinguished. Nowadays, many samples are measured without rotating them as in former times. The reason here too can be found in the homogeneity of the magnetic field. If they are not rotated completely evenly the result is a worse spectrum. It is, therefore, better in many cases to compensate for any irregularities by shimming. However, it is even better to ensure that as few irregularities as possible occur with an accurately specified quality. Most NMR spectroscopy workers have got used to rolling NMR tubes on a flat surface as a rough test. This way of sorting out the “bananas” makes sense as a preliminary test in practice, but of course it is not adequate for production development and production control purposes. 637 parafilm General usage: Wrapping and sealing samples CATALOGUE # 08PM996 pasteur pipettes General usage: Taking up a small amount of liquid for transfer Material: Neutral glass Accessories: Rubber teat Pack size: 250 Material: Polyethylene Pack size: 500 LENGTH mm 150 230 CATALOGUE # 05PP150 05PP230 CAPACITY ml 1.5 5.0 CATALOGUE # 1K88336 1K88337 Can be deep-frozen with contents.
