The DrySyn SnowStorm range from Asynt is designed to provide an attractive solution for scientists undertaking low temperature chemical reactions and studies.
Unlike traditional reaction cooling methods, such as ice, dry-ice and liquid nitrogen; accurate and prolonged temperature control on a DrySyn SnowStorm is regulated by an external thermostatic circulator. This not only eliminates the risk of temperature fluctuations due to perishable coolants, but can also improve sustainable use of resources.
As well as allowing unattended operation (even overnight), active temperature control on the instrument range enables responsive control of exothermic reactions, constant rate cooling to enhance polymorph studies and significant improvement in reaction reproducibility. It’s ability to agitate and cool in parallel can improve productivity.
The Snowstorm systems deliver precise temperature control of reactions from -60 to +150 °C and have been designed to be user friendly and practical, with a small bench top footprint. The DrySyn SnowStorm ONE enables controlled chemistry to be conducted on single flasks up to 1 litre in size, whilst the SnowStorm MULTI allows for up to three 100 ml parallel reactions to be undertaken.
The use of a weighted silicone seal prevents the formation of ice around the glassware on these systems. For smaller scale experiments, the DrySyn Snowstorm Reactor allows increased throughput and screening of up to 27 vial-based reactions. Purging the dome with nitrogen/argon prevents the formation of ice around the vials at sub-ambient temperatures.
