DrySyn® SnowStorm Reactor

The DrySyn® Snowstorm reactor offers an attractive solution to low temperature reaction chemistry.

Purging the dome with nitrogen / argon prevents the formation of ice around the reactors at sub-ambient temperatures.

Active temperature control from -30 oC to +150 oC  permits unattended operation of up to 27 vials at any one time.

With a small bench top footprint, the DrySyn Snowstorm allows increased throughput and screening without taking up valuable fume hood space.

Our gallery images show the DrySyn SnowStorm reactor with both Grant and Julabo chillers.

Made in the UK.
