Cool-It

Insulated cooling bowls for safe cooling and stirring down to -78 °C

Cool-It™ insulated bowls provide a safe and practical alternative to fragile glass dewars and unstable plastic bowls for cooling and stirring laboratory vessels. Designed for use on standard laboratory stirring hotplates, they accommodate round-bottom flasks, beakers and test tubes while maintaining low temperatures for extended periods.

The compact design, combined with a robust insulated construction, helps keep reactions colder for longer while improving safety during low-temperature laboratory work.

Longer cooling performance

Cool-It bowls are designed to maintain temperatures below -70 °C significantly longer than conventional alternatives.

Compared with a plastic bowl, Cool-It can keep samples below -70 °C for up to five times longer. Compared with a traditional glass dewar, reactions can remain below -70 °C for up to twice as long.

An optional two-piece lid further extends cooling performance by up to 20%. The lid also helps minimize condensation and ice formation on the reaction vessel, maintains visibility of the flask contents and reduces spitting from the cooling mixture.

Durable and virtually unbreakable construction

The bowls are manufactured from a chemically resistant HDPE outer casing with a high-quality insulated foam core. This combination provides excellent thermal insulation while making the bowls virtually unbreakable, unlike conventional glass dewars.

Designed for safer laboratory operation

Cool-It features an ergonomic handle and a non-drip pouring spout, making solvent disposal safer and reducing the risk of accidental spills.

The insulated exterior minimizes frost formation, helping protect the stirring hotplate against moisture ingress. The bowl also sits securely on the hotplate, reducing the risk of spills or accidental movement during operation.

Compatibility and available sizes

Cool-It bowls are compatible with all major brands of laboratory stirring hotplates equipped with a 145 mm diameter top plate. An optional adapter plate is available for hotplates with a 135 mm top plate.

Two bowl sizes are available:

• Small bowl for round-bottom flasks up to 400 mL
• Large bowl for round-bottom flasks up to 2 L
