SD-12 Circular Water Bath Nitrogen Blower Introduction: 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 quickly, continuously, and controllably blow nitrogen gas onto the surface of the heated sample. Based on the evaporation rate and boiling point of the concentrated solvent, the heating temperature is set to achieve rapid anaerobic concentration of a large number of samples. The water bath nitrogen blower includes a base and support device, a sample holder, and a gas distribution system. The test tube is fixed in position by a spring-loaded test tube clamp and support plate. Each sample grade has a numerical code; The gas reaches the gas distribution system through a flow meter, and a flexible guide tube guides the gas into valves and stainless steel needles at each position, blowing the gas onto the surface of the sample to rapidly evaporate the solvent. According to the size of the test tube and the amount of solvent, each airway can be independently raised and lowered to the appropriate height. characteristic: 1. Real time temperature display and time countdown display; 2. Adopting a constant temperature water bath, it has good and uniform heat transfer, which is conducive to rapid heating and temperature control. 3. Sample size: 12 digits, fixed and positioned with a spring test tube clamp, each sample grade has a numerical code. 4. Strong compatibility, suitable for test tubes (diameter 10-29mm), conical flasks, centrifuge tubes, sample capacity 1-50ml. 5. High temperature control accuracy, wide temperature control range, temperature CNC digital display, and easy calibration. 6. With a circular structure, it can rotate freely 360 degrees, making it easy for the sample holder to enter and exit the water bath. The operation is simple and convenient. 7. Built in liquid level sensor, anti dry burning buzzer alarm. 8. Free lifting needle valve tube, adjustable needle valve can control the gas flow rate of each sample needle. 9. All components are corrosion-resistant, resistant to organic solvents, durable, and easy to clean.
