Economical Cooling for Rotary Evaporators

LS Series Chillers are capable of simultaneously
cooling two or more benchtop rotary evaporators, and
provide particularly efficient and economical cooling at
temperatures between 0°C and +10°C. Their powerful heat
removal capability, combined with a compact design, makes
them ideal for any low temperature cooling application
where bench space is limited. They can also be placed on a
mobile cart accessory, below a bench.
