Nitrogen concentration is high precision temperature control instrument by microcomputer processing and PID control method are combined to form, its working principle is to fast, continuous and controllable nitrogen blowing to the heating surface of the sample, according to the concentration of solvent evaporation rate and the boiling point, set the heating temperature, concentration of a large number of samples to achieve fast. The instrument adopts aluminum plate heating module, which has good heat transfer and uniform heat transfer. Nitrogen is blown to the surface of the sample to achieve the anaerobic concentration of liquid samples. Blowpipe is independent of each other, and will not cause cross contamination. Each gas channel on the gas distribution assembly can be combined or used alone. The system has the advantages of high temperature control precision, wide temperature control range, temperature digital display and temperature calibration. The product is beautiful and easy to use, safe and reliable to use.

Technical parameter

Nitrogen concentration JN300-4（RT+5°C-150°C）

Nitrogen concentration module

Note: the gas flow of nitrogen concentration JN300-4 can control each of the gas needle, no flow control valve can realize the single and multiple needle and gas flow control instrument; according to the host configuration module, JN300-4 module 2, module module can be selected in the area, a standard module for A-G modules need extracharges the former, consulting service personnel, custom modules required period, please confirm in advance!
