Asynt – DrySyn MAXI Kit

The DrySyn Pear-Shaped Flask System is designed to allow scientists to perform safe, productive heating and stirring experiments with pear-shaped flasks such as those commonly used with rotary evaporators.

Pear-shaped flasks are typically used for evaporating solutions to dryness post synthesis using a rotary evaporator.  The ’rounded V’ shape of the flasks enables solid materials to be scraped out more efficiently than from a round bottomed flask.

Providing excellent heating and stirring performance but without the inherent potential risks and mess of an oil bath, our DrySyn Pear-Shaped Flask System is a family of heating blocks perfectly designed for pear-shaped flasks from 100 mL to 1000 mL.  This world-renowned system is enabling laboratory scientists to work in a safer, cleaner and more efficient way.  Removing messy and potentially hazardous oil baths from your laboratory setup without the necessity to change your chemistry is beneficial to the environment on a larger scale as well as your direct environment.
