Lab Equipments
Pipestem Triangle
 For supporting crucibles and dishes when heating on a
gas burner or other similar heat source.
Evaporating Dish
Utility Tongs
 for handling cylindrical apparatus such as test
tubes, flasks,
3-Leg Beaker Support Stand
 For supporting small objects (such as crucibles or
evaporating dishes) over a burner
Beaker Tongs
 Beaker tongs designed to hold liquid filled beakers
from 50mL to 2000mL capacity.
Thermometers
Glass Stirring Rods
 Fine stirring rods are solid flint glass with fire-
polished rounded ends
Short-Stem Glass Funnels
Glass Dropping Pipette
Thin Stem Pipettes
Disposable Plastic Dropper
Heavy-Duty Spring Scale (Metric/English)
*The large size makes it easy to read and capable
of measuring more weight than most
other scales of its type
Balance
 Measures the mass of an object
Beam Balance
Hot plate
 Used to heat liquids
Rubber Stopper
 solid, one-hole, two-hole, and three-hole
stoppers in an assortment of sizes.
Spot Plate
 Chemically inert and unbreakable, polystyrene
can be used with concentrated acids
Erlenmeyer Flasks
 can be heated and used with acids, salt solutions,
and organic solvents.
Florence Boiling Flasks
 Their round body and long neck are ideal for
boiling liquids without excessively rapid
evaporation.
Beaker
 With uniform wall thickness; white enamel, double-graduated
metric scale
 the beakers can be heated
 used with acids, salt solutions, and organic solvents.
Wash Bottles
 Solutions can be poured easily by squeezing the bottle
lightly
Filter Paper
Petri Dishes
Watch Glasses
 watch glasses provide a safer way to perform
evaporations on hot plates or in ovens
Safety Drench Shower
 offers a constant flow of water to wash
contaminants from the entire body
Multi-Purpose Fire Extinguisher
 discharged in a thick stream to blanket fires.
Stand 6′ away and aim at the base of the fire to
discharge the tank
safety goggles, vinyl apron, gloves
pH paper
 Used to measure how acidic or basic a substance
is
Disposable or transfer pipette
 Draws a liquid up by suction and allows transfer to
other solutions
Mortar and Pestle
 Used to grind and mix substances
Test Tube Holder
 Provides a safe way of transferring a hot test
tube to a test tube rack
Weigh Boat
 Prevents substances from coming into contact
with the balance plate when massing solids
Graduated cylinder
 Best way to accurately measure the volume of a
liquid
Spatula
 Used to scoop solids
Test tube brush
 Used to clean the inside of a test tube
Safety goggles
 Protect your eyes
Glass slide
 Provides a surface to lay things on that you wish
to view using the microscope
Centrifuge
 Used to separate substances based on mass; does
this by spinning tubes in a circle at a high rate of
speed
Test Tube Rack
 Holds test tubes upright
Forceps
 Like tweezers, they are used to grasp small
objects
