N-EVAP®OPERATION
Operation
Planning and Preparation
It is important to thoroughly understand the procedures and equipment operation prior
to the use of the equipment. Nitrogen evaporation requires a balance of sample volume,
nitrogen flow, needle position and adjustment. Improper use can impair performance,
contaminate samples or result in loss of samples. Environmental conditions are also
important, examples include use of dry or wet heating media, hood airborne
contaminates, gas purge purity, and sample handling procedures. If you are unfamiliar
with the use of the N-Evap System or are working with a new procedure, it is
recommended that a trial run be made using a sample blank to determine optimal
operating conditions.
The N-EVAP System is designed to handle multiple samples simultaneously up to the
capacity of the equipment. Glass or plastic tubes with an outer diameter of 10 to 30mm
and up to 150mm height may be accommodated. Centrifuge tubes, scintillation vials,
small beakers and Erlenmeyers (50 ml) may also be used. Choice of SS needles or
disposable glass pipets (adapters) are available.
The N-EVAP System is manufactured utilizing inert materials. The translucent silicone
rubber tubing used in the gas distribution system is certified 100% Phthalate free.
