45 Position N-EVAP

The most cost-effective N-EVAP model

The time-tested, durable 45 Position N-EVAP provides the least expensive price per position of all our N-EVAPs. The evaporative system, along with the standard flow control and pressure reducing regulator, enables the operator to achieve the desired level of concentration with efficient nitrogen usage. Our unique dual band spring hoist assembly ensures easy and effective operator use. Additionally, the 45 position N-EVAP includes a side control box.  Timed, digitally controlled water bath temperatures provide 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.  The heat can also be shut off with the gas after a timed cycle.
