34/45 Position Nitrogen Evaporator
Our 34 and 45 position nitrogen evaporators (Catalog #11634 and #11645) offer the largest number of sample positions in our N-Evap line. Timed, digitally controlled water bath temperatures provide very even evaporation rates. Timed, automatic gas flow slows evaporation to a minimum once the timed cycle has been completed. Our unique band spring hoist assembly ensures easy, effective operator use. These time-tested, durable systems provide the least expensive price per position of all our circular 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. Acid resistant models are available. All units are engineered to UL specifications for laboratory use. Please contact us for any specific questions about these instruments.
