Asynt enhances Drysyn heating and cooling system

Asynt has introduced the latest Drysyn heating and cooling system, which has the flexibility and performance to satisfy a range of temperature control requirements in the chemistry laboratory.

It is capable of heating a single flask or creating a parallel sub-ambient reaction station.

Design improvements have resulted in faster heating and cooling - the latest Drysyn versions are 25 per cent faster than messy, dangerous oil baths and can heat a reaction flask to 300C.

At the other end of the temperature range, a standard laboratory chiller supplies the cooling for the recently patented Drysyn Cool.

In independent tests, Drysyn Cool gave better temperature control, faster cooling (to -30C) and a better ability to cope with exotherms than a conventional ice bath.

Drysyn systems are available for single or multiple reaction vessels with volumes from 1ml to 5,000ml.

They combine a small footprint with excellent reaction visibility, according to the company.

All models are fully compatible with magnetic stirring or the novel Vortex overhead stirrer system can provide powerful directly driven stirring for up to three flasks, improving performance with viscous mixtures and largely eliminating the grinding effects that can occur with magnetic stirrers on solids, especially crystals.

According to Martyn Fordham, Asynt's managing director, more than 25,000 Drysyn laboratory heating and cooling blocks have now been supplied worldwide.
