N-evap 112 organomation meyer nitrogen evaporator
Organomation Associates Meyer 24 place 112 N-EVAP
The instruments consist of a base and stand assembly, sample holder,
gas distribution system, Thermometer, and several needles.
Test tubes are held in place by a spring-loaded sample holder and support tray.
Each position is numbered. The gas passes through an adjustable flow meter
to the distribution manifold. Flexible tubing leads to valve-tube assemblies
at each position. Depending on the test-tube size and solvent volume they can be
individually raised or lowered to the correct height.
Needles or glass pipets blow gas onto the surface of the solution resulting
in rapid evaporation of the solvent. All materials used are laboratory
quality and can withstand contact with organic solvents.
The Series N-EVAP analytical evaporators are time saving and convenient instruments for
preparing samples for liquid chromatography, gas chromatography and mass spectometry.
They find use in applications where it is necessary to concentrate multiple samples in order to analyze the residue.
This is accomplished by the proven technique of allowing Nitrogen onto the surface of a heated sample.
The result is a fast and controlled operation.
