CM-24 type water bath nitrogen blowing instrument Introduction: The instrument includes a base and bracket device, a sample rack and a gas distribution system. The test tube is fixed in position by a spring-loaded test tube clamp 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 introduces the gas to the valve and stainless steel needle at each position, blowing the gas to the sample surface, thereby quickly evaporating the solvent. 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. The temperature of the round stainless steel water bath can be adjusted and controlled. It can accurately maintain a constant water temperature in the range of room temperature to 99 ℃. Features: 1. Suitable for test tube (diameter 10 ～ 29mm), conical flask, centrifuge tube, sample capacity 1 ～ 50ml 2. Number of samples: 24 bits, the sample holder of the spring test tube clamp is fixed and positioned, and each sample position has a digital number 3. The needle valve tube that can be lifted up and down freely. Each air flow can be controlled independently by the imported regulating valve. It can be lifted up and down, and the surface of the sample is purged with nitrogen and air. 4. Circular structure, compact size, occupy less space in the fume hood. The sample tray and purge rack can be rotated at the same time to prevent cross contamination of the sample. 5. The standard gas needle length is: 150mm 6. Circular constant temperature water bath, temperature liquid crystal display, can be timed, water bath temperature: room temperature ~ 99 ℃ 7. All parts are resistant to organic solvents. 8. When concentrating toxic solvents, the entire system can be placed in a fume hood 9. Using intelligent LCD temperature controller, PID technology can be used regularly and can achieve over-temperature alarm and anti-dry function 10. Japan original SMC TUS hose, water bath / purge rack is made of 304 stainless steel 11. Double gas path, can be connected to nitrogen source (suitable for sensitive samples) and air source (suitable for stable samples) Technical Parameters: 1. Temperature range: room temperature ~ 99 ℃ (liquid crystal display) 2. Temperature control accuracy ± 0.5 ℃ 3. Test tube size: 10 ～ 29mm 4. Gas flow: 0 ～ 15L / Min, built-in nitrogen flow valve 5. Gas consumption: 330ml / min / sample (adjustable) 6. Heating method: constant temperature water bath 7. Liner size: φ40x20cm Application areas: 1. Pesticide analysis: vegetables, fruits, grains, plant tissues, etc. 2. Pharmaceutical drug testing: Chinese medicine pharmacy and drug testing 3. Environmental analysis: drinking water, groundwater, polluted water, etc. 4. Biological analysis: serum, plasma, blood, urine 5. Commodity inspection: inspection of dioxin, croft, etc. 6. Food and beverage: milk, wine, liquid beverage
