Introduction:
The WH-12 water bath nitrogen blowing instrument is a high-precision control instrument formed by a combination of microcomputer processing and PID control. Its working principle is to rapidly, continuously and controlly blow nitrogen gas onto the surface of the heated sample according to the concentrated solvent. The evaporation rate and boiling point, set the heating temperature, and achieve rapid concentration of a large number of samples. The instrument adopts a water bath thermostat, which has good heat transfer and uniform heat transfer, which facilitates rapid heating and rapid temperature control. Nitrogen gas is blown onto the surface of the sample to achieve anaerobic concentration of the liquid sample. The blowpipes are independent of each other and do not cause cross-contamination. Each gas needle channel on the gas distribution assembly can be used in combination or separately. The system has high temperature control precision, wide temperature control range, temperature digital display and convenient temperature calibration. The appearance of the product is beautiful and elegant, the operation is simple, and the use is safe and reliable. Features:
1) The overall appearance of the instrument is elegant, circular structure, free to rotate, convenient for the sample holder to enter and exit the water bath, easy to operate;
2) Free-lifting needle valve tube, independently adjustable needle valve, control the gas flow rate of each sample gas needle;
3) LED digital display temperature and time, water bath temperature: room temperature +5 ° C -100 ° C;
4) All stainless steel parts are used, all parts are corrosion resistant and resistant to organic solvents;
5) Built-in liquid level sensor to prevent dry beep alarm;
6) Wide application range: suitable for test tubes (10-29mm in diameter), conical flasks, centrifuge tubes, sample volume 1-50ml;
