Products blowing nitrogen bath KDB-12 instrument using internationally recognized technology, through the heated sample surface nitrogen blowing Sample Enrichment and thus make analysis time, to meet the need for rapid detection. This method is time-saving, simple operation, easy to control, and low cost. The instrument includes a base and stand assembly, sample holder and gas distribution system. Tube through the tube with a spring clip and the support plate to a fixed location. Has a number of bits per sample number; gas reaches the air distribution system through the meter, a flexible guide tube of the gas into each position and the stainless steel needle valve, the gas blown to the sample surface, so that rapid evaporation of the solvent. According tube size and how much solvent, the airway can be independently lift to the appropriate height. Round stainless steel bath temperature can be adjusted and can be controlled at room temperature ~ 99 ℃ range of temperature can be accurately maintained constant. Product Features 1. Apply to a test tube (diameter 10 ~ 29mm), flasks, tubes, sample volume 1 ~ 50ml 2. Samples median: 12, spring tube clip sample holder fixed positioning, bits per sample has numbered 3 free movements of the needle valve tube, adjustable needle valve controlling the gas flow tube 4 circular structure, rotating freely, convenient sample holder out of the water bath, easy to operate 5. standard gas needle length: 150mm 6. round water bath, temperature display, water bath temperature: room temperature ~ 99 ℃ 7. All parts can be resistant to organic solvents. 8 in the concentration of toxic solvents, the entire system can be placed in a fume hood 9. Prevent dry and alarm functions Applications 1.
