Sub-ambient reaction systems for crystallisation studies

Overnight runs can be performed with complete confidence

The new DrySyn SNOWSTORM

Isleham, UK — Available in a choice of configurations, Asynt DrySyn?? SnowStorm systems provide controlled cooling for sub-ambient chemistry without the need for jacketed reaction vessels or ice baths. Operating with a suitable chiller / circulator, DrySyn?? SnowStorm systems give accurate, stable temperature control down to -50 ??C and up to +150 ??C,

Thus, making them perfect for crystallisation studies and screening polymorphs.

DrySyn “SnowStorm One” is designed to accommodate a single standard round-bottomed flask from 50 ml to 1000 ml. The DrySyn “SnowStorm Multi” takes up to 3 round bottom flasks from 25 ml to 100 ml, or up to 39 vials in parallel.

All SnowStorm units offer powerful agitation using a magnetic stirrer drive. Widely used for cooled reactions the traditional ice bath is limited to temperatures around 0 ??C, requires constant attention and is subject to temperature fluctuations.

By comparison, the stable controlled performance of DrySyn SnowStorm units means that overnight runs can be performed with complete confidence.
