Sample Concentrator NK200-1A utilizes 96-gas-needles is mainly used for concentrating or preparing sample in batch. Such as drug screening, hormone analysis, liquid phase and mass spectroscopy in the analysis of sample preparation. It works by blowing nitrogen in the surface of sample which is being heated to accelerate evaporating and separating the solvent in the samples without oxygen.

Features:
The heater heats the sample rapidly to the evaporation temperature, and at the same time, the gas is blown to the surface of the solution through the gas needle, which promotes rapid evaporation of the solution and concentration of the sample.
The height of the air cavity can be adjusted. The length of a standard gas needle is 80mm.
The entire equipment can be put into ventilation cabinet when the concentration sample in
toxic solvents.
Built in overheat protection, automatic fault detection and fault beep alarm devices.
LED displays immediate temperature and diminishing time.
