Nitrogen Evaporator, N-EVAP Series, Acid Resistant Coating, with Water Bath (30-90°C and 550 W), Analog Control, 12 Sample Positions
Article no.: 11155-RT
First introduced in 1959, the 12 position N- EVAP has evolved to be an extremely durable, time tested and highly affordable member of the N-EVAP line. It has the smallest footprint of the N-EVAP line, helping to conserve valuable bench space.
This N-EVAP has an adjustable spring design, making it ideal for laboratories that will be using a wide variety of sample tube sizes. The N-EVAP’s circular rotating design permits each sample to be accessible from the front of the instrument for easy insertion and retrieval.
This model provides controlled concentration of samples using nitrogen gas blowdown along with a heated water bath. The needles can be raised and lowered at each individual sample position. The chrome plated needle valves are individually milled from solid brass, and allow precise adjustment of the gas flow rate at each sample position. This promotes efficient and safe sample reduction with minimal nitrogen waste.
The stainless-steel construction of the bath ensures that the instrument is long lasting.
Small Footprint
N-EVAP Model 111 requires under one square foot of bench space
Very Flexible Design
An adjustable sample holder design fits a wide variety of sample tubes and vials at once
Customizable Structure
For tubes outside of the standard 10-30 mm range, you can choose optional sample holder to accommodate tubes with an outside diameter of 5-16 mm
Individualized Control
At each individual sample position, the gas flow can be controlled via a precision needle valve. This is ideal for the simultaneous evaporation of samples with varying evaporation end points.
Standard Features
