Cool-It - the unbreakable dewar
Cool-It replaces fragile glass dewars, unstable plastic bowls and keeps your chemistry colder for longer. The compact and virtually unbreakable Cool-It insulated bowls are designed to fit onto a standard stirring hotplate to cool and stir round bottom flasks, beakers or test tubes.
Cool-It keeps it cooler for longer
Cool-It will keep your sample below -70°C for up to 5 times longer than a plastic bowl. Cool-It will keep your reactions below -70°C for twice as long as a glass dewar.
Large and small bowl options
Small Cool-It bowl for flasks up to 400ml. Large Cool-It bowl for flasks up to 2 L.

Unbreakable
Cool-It bowls are manufactured from a robust, chemically-resistant HDPE casing encapsulating a high quality insulated foam core. This combination of tough composite materials provides excellent insulation and (unlike fragile glass dewars) is virtually unbreakable.

Easy pour spout and handle
Cool-It’s unique non-drip spout and ergonomically designed handle makes the disposal of solvents much safer and easier; avoiding accidental spillages and creating a safer working environment.

Optional lid increases cooling time by 20%
The two piece lid will help to keep your reaction cool for up to 20% longer, minimising condensation and ice formation on your flask (maintaining visibility of the contents) and prevents spitting from the cooling mixture.

Protects your stirrer and minimises spills
Cool-It minimises frost on the outer surfaces, protecting your stirrer from moisture ingress. It is also designed to fit securely onto the top plate minimising accidental spills.

Cool-It fits on to all popular brands of stirring hotplate
Fit on all leading hotplate brands with a 145mm Ø top plate; optional adapter plate for 135mm Ø top plates.
