■■ Economical
and efficient
ACE DynaBloc anodized aluminum blocks are ideal for heating and mixing solutions in
a variety of vials and small round bottom flasks.
ACE DynaBloc heating blocks use a universal base plate, which fits easily on top of
any circular-top hotplate stirrers.
The ACE DynaBloc system is low-cost, and its efficient heating blocks utilize a wide
range of standard laboratory glassware. They can be used for stirring and/or heating
multiple samples in applications such as digestion, extraction, distillation, and synthesis.
The system is easy to set up, allows switching from vials to flasks in seconds, and is
also easy to disassemble for cleaning. The configuration of the vial/flask holes allows for
optimum heating and mixing in every well.
Use ACE DynaBloc heating blocks with your standard labware and hotplates for
highly economical and efficient heating/stirring.
DynaBloc Base Plate
Anodized aluminum base plate, for use with DynaBloc heads, fits the standard circular
135 mm or 145mm diameter stirrer/hotplate top. The base has a hole in the side to
accommodate a standard thermocouple sensor to measure the heat at the base.

Cylindrical, for Vials & Tubes
Anodized aluminum blocks for use with Base Plate. Pre-drilled openings for standard-size
glass vials and tubes including small dram vials, chromatography vials, scintillation vials,
EPA vials, VOC vials, and standard test tubes. The blocks can be separated from the base
plate for easy cleaning and handling. All blocks have a predrilled hole to accommodate
sensor probe and have another hole to accommodate the T-handle extractor for easy
removal of the block, even when hot. Order base plate, block and
T-handle separately.

Anodized aluminum blocks are machined to accommodate small round bottom flasks and
small Erlenmeyer flasks. The blocks fit the universal base plate, and have one hole to
accommodate the extension rods and the T-handle extractor which assists
moving the blocks even while hot. The blocks also have a hole for a temperature
sensor probe. Short support rod (31 cm long) is for supporting flasks in the flask
89083-392
blocks; long (61 cm) rod supports condensers and other taller glass apparatus.
Clamp devices are necessary to stabilize glassware while in blocks. Order base
plate, block, clamp device, and support rod separately.
