Nitrogen Evaporator, N-EVAP Series, Standard, without Controller and Heater, 45 Sample Positions
Article no.: 11645-O
The 45 position N-EVAP has the largest number of sample positions in the N-EVAP line, and provides the least expensive price per position.
Like the rest of the N-EVAP line, the 34 position N-EVAP has an adjustable spring design to accommodate a range of sample tube sizes. This model uses nitrogen blow down to gently concentrate delicate samples at ambient temperature.
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 N-EVAP’s circular rotating design permits each sample to be accessible from the front of the instrument for easy insertion and retrieval.
Gentle Evaporation
N-EVAP nitrogen evaporators combine nitrogen blow down with a heated bath or ambient temperature to gently concentrate delicate samples
Very Flexible Design
An adjustable sample holder design fits a wide variety of sample tubes and vials at once
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.
Concentration at Ambient Temperatures
For analytical techniques which require the evaporation of organic solvents at ambient temperatures
Standard Features
+ Paper filled air filter for nitrogen supply
+ Adjustable flow meter to conserve nitrogen gas (0-30 LPM)
+ Phthalate free silicon tubing eliminates contamination concerns
+ High temperature limit switch for safety
+ Precision needle valve tube assembly
+ Needles, 102 mm x 19 gauge with chrome plated brass hub and stainless-steel shaft
+ Dual pulley spring assembly for easy raising and lowering of the samples and gas distribution manifold
+ This model comes with a base and stand assembly instead of a heated bath. These instruments are designed for evaporation procedures performed at ambient temperature
