Product Description:
The SD-12 water bath nitrogen blowing instrument is a high-precision control instrument that combines microcomputer control technology and PID control. Its working principle is to blow nitrogen quickly, continuously and controllably to the surface of the heated sample, according to the concentration of the solvent. Evaporation speed and boiling point, set heating temperature, realize rapid oxygen-free concentration of a large number of samples. The water bath nitrogen blowing instrument includes a base and a support device, a sample holder and a gas distribution system. The test tube is fixed in position by a test tube clamp with a spring and a support plate. Each sample position has a digital number; the gas reaches the gas distribution system through the flow meter, and the flexible guide tube guides the gas into the valve and stainless steel needle at each position, blowing the gas to the sample surface, so that the solvent volatilizes quickly. According to the size of the test tube and the amount of solvent, each air duct can be independently raised and lowered to a suitable height.
