How To Make The Best Use Of Heating & Cooling Temp. Control System?

Heating and cooling temperature control system is aways used for double layer glass reactor
, three layer glass reactor
and rotary evaporator
,etc. In chemistry laboratory, for the material which couldn’t react under normal temperature, you need to create a high or low temperature conditions to prompt material reaction. Generally, after finish charging material in glass reaction vessel, you need to choose heat-conducting medium (ethyl alcohol or liquid nitrogen for low temperature / water for 0-90℃ / silicon oil for high temperature) which is added in glass reactor jacketed layer, finally use heating & cooling temp. control system to control material reaction temperature.

So heating and cooling temperature control system as conventional laboratory instrument, how to make the best use of it? 

And make research more efficient & accurate finally? Let’s solve this problem together through actual application examples.
