34 Position N-EVAP

Digitally controlled temperature for water bath evaporation

Additionally, the 34 position N-EVAP includes a side control box, which provides timed and digitally controlled water bath temperatures to produce even evaporation rates. The pressure regulator and timer combine to allow timed automatic gas flow cut off which slows evaporation to a minimum once the timed cycle has been completed.  In order to prevent damage to delicate samples, the timer also provides the option for the heat to shut off once the cycle is complete.
