Asynt Launches Sub-ambient Reaction Systems

Asynt’s DrySyn® COOL systems provide controlled cooling for sub-ambient chemistry without the need for jacketed reaction vessels or ice baths.

DrySyn COOL accommodates a single standard round-bottomed flask from 50ml to 1000ml and with a suitable chiller/circulator gives accurate temperature control down to –30°C. DrySyn Multi COOL takes up to 3 flasks from 25ml to 1000ml. Both are compatible with standard magnetic stirrers.

The traditional ice bath is limited to temperatures around 0ºC, requires constant attention and is subject to temperature fluctuations, whereas the long term, controlled performance of DrySyn COOL systems means that overnight runs can be performed with complete confidence.

Designed for use with DrySyn COOL, the new Asynt ADS-GR150 chiller/circulator offers outstanding performance for routine and sophisticated applications.

A powerful integral circulating pump and up to 250W of cooling power are combined with Intelligent Control Optimisation™ (ICO) to achieve PID temperature control, a sophisticated control technique that combines optimum stability with a response to load changes such as might occur with reaction exotherms.

The control unit incorporates a number of other features including PC control, a user calibration facility, and memory capacity for up to 30 steps of temperature programming.
