45 Position N-EVAP
Nitrogen Evaporator
DESCRIPTION
Our 45-position nitrogen evaporator (Catalog # 11645) offers the largest number of sample positions in our N-EVAP line. The sample holder has dual circular rings. The outer ring has 30 positions and can accommodate samples with an outside diameter of 10-19 mm The inner ring has 15 positions and can accommodate samples with an outside diameter of 16-30 mm and a minimum height of 70 mm.
This time-tested, durable system 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.
