Hotplate makes an easier life for
chemists
Asynt has applied its expertise in chemical synthesis to the design of a new hotplate system that eliminates most of the problems and nuisances experienced with traditional hotplates
For example, a common problem, particularly with viscous materials, is that magnetic stirrers will decouple from the drive during start up and may never recover This new design maintains efficient magnetic coupling by ramping the stirrer speed, ensuring continuous and effective stirring even with up to 20 litres of liquid

Any standard hotplate stirrer can be instantly converted to a flexible reaction station capable of running up to three parallel reactions in conventional round-bottomed flasks or 12 in tubes or vials
800 watts of heating power combined with the possibility of using an external Asynt immersion sensor gives fast heating over a 20-300C temperature range with the assurance that the solution is actually at the desired temperature.
The hotplate itself is made of silumin, an aluminium/silicon alloy with excellent corrosion and scratch resistance that is further enhanced with a ceramic coating.
For extra safety, the external housing is hermetically sealed so that if spillages or leaks do occur, liquid and gases cannot reach the drive or electronics.
When more control accuracy is required, the unit can be used with an Asynt electronic temperature controller, giving 0.5C temperature control and the added convenience of direct digital temperature readout.
This hotplate is fully compatible with Asynt's popular DrySyn range of dry heating blocks that give effective temperature control (up to 250C) of single or multiple reaction flasks without the use of messy, potentially hazardous oil baths.
