12 circular water bath nitrogen blowing instrument

 12 circular water bath nitrogen blowing instrument Product description: JTONE brand circular water bath nitrogen blowing instrument purge and trap technology use, while the sample temperature control heating, an inert gas such as nitrogen through fast, controlled, continuously blown sample the surface of the sample solution to achieve rapid anaerobic concentrated. When this method saving, convenient and accurate. Widely used in food safety, pharmaceutical, pesticide residue testing, clinical pharmacokinetics and other fields. 12 circular water bath nitrogen blowing instrument main features: 1. circular water bath nitrogen blowing instrument for test tubes, flasks, tubes and other containers of different sizes. 2. Sample median: 12, sample holder spring test tube holder fixed position, each sample has figures. 3. The test tube holder and the supporting plate to a fixed position by the tube with a spring, can be adjusted in the height direction. The free lift of the needle valve tube, according to the size and number of tubes solvent, the airway can be independent of each lift to the appropriate height, while the adjustable needle valve can control the gas flow tube. 5. The circular structure, rotatable, easy sample holder access to the water bath, easy to operate. 6. intelligent digital thermostat can be timed, dual digital display, adjust the PID technology can achieve temperature alarm and anti-dry. 7. All parts of uniform circular nitrogen blowing instrument quality stainless steel, can be acid and other organic solvents. 8. regulating valve: Import control valve, ensure good air tightness and durability. 9. In the concentrated toxic solvents, the entire system can be placed in a hood. 12 circular water bath nitrogen blowing instrument technical parameters: Model JT-DCY-12Y JT-DCY-24Y Processing of samples 12 independent control 24 independently controlled heating circle circular water bath water bath tube range 10 ~ 55mm 10 ~ 29mm tray lift height 0--150mm 0--150mm sample disc rotation space 360 ??° C 360 ° C Temperature Accuracy ± 1 ℃ ± 1 ℃ temperature range of room temperature --- 100 ℃ --- 100 ℃ temperature control mode 4 digit display / PID regulator / over-temperature alarm 4 digit display / PID regulator / over-temperature alarm timing 0 ~ 99h59min 0 ~ 99h59min controlled gas flow 0-15L / min controlled 0-15L / min nitrogen consumption 330ml / min / sample 330ml / min / sample power 1000W 1000W Weight 10KG 12KG 12 位 circular water bath nitrogen blowing instrument Dry nitrogen blowing instrument and a water bath nitrogen blowing instrument in accordance with the difference between nitrogen blowing instrument is divided into different heating dry bath nitrogen blowing instrument, water bath nitrogen blowing instrument. In the preparation of gas chromatography, liquid chromatography and mass spectrometry analysis of samples using, often used to dry nitrogen blowing instrument and blowing nitrogen bath crystal sample instrument for purification. Because time-saving, easy to operate, easy to control, etc., and is widely used in pesticide analysis, environmental, biological products, food, pharmaceutical and other industries. Dry bath nitrogen blowing instrument and the biggest difference is that the water bath nitrogen blowing instrument both different heating methods used, and therefore applicable to the performance of the samples are not the same. Dry nitrogen blowing instrument of heating thermal conductivity and strong aluminum block is heated, dry heat, warming rapidly and uniformly, less pollution; sample than the median, you can select the number of holes needed: such as 12 holes, 24 holes etc; heater the sample is rapidly heated to evaporation temperature while blowing gas through the gas needle to the surface of the solution, prompting rapid evaporation and sample concentration solution. Water bath nitrogen blowing instrument structure consists of a base and stand equipment, sample holder and gas distribution system components, test tube by tube with a spring clip and the support plate to a fixed position, the gas through the meter reaches the gas distribution system, a flexible guide tube into the gas each position valves and stainless steel needle, the samples were blown to the sample surface, so that the rapid evaporation of the solution. Suitable for test tubes, flasks, centrifuge tubes, beakers and other containers, versatility; water bath, intelligent climate control. Heating, lift, gas supply, drainage, the timing can be controlled independently, operate freely. Dry nitrogen blowing instrument to compare and heated water bath nitrogen blowing instrument method: 1. water bath is usually necessary to heat the tube is placed in a beaker of water, heat, water heating, water and then heat to the tube, can be seen as is an indirect heating process, unlike the dry direct contact heat source; In addition, as the water bath process, you can insert a thermometer in a beaker of water, for real-time observation of the water temperature can be well controlled so that the temperature of water, dry heating law difficult to achieve real-time control of the temperature. 2. The process of heating the tube is immersed in a water bath beaker of water evenly in all parts; and too dry heating is usually more than the bottom of the tube is heated in the upper part. 3. Slow cooling water bath heating up too slow, and the heating temperature does not exceed 100 ℃, is a "moderate" heating; dry heating up fast faster cooling, heating temperature up to about 180 ℃, it can be considered a "emergency fire" heating, two heating methods suitable for different material sample. 4. Some organic substances should not touch the fire, it is necessary to use a water bath heating mode; and there are a number of organometallic reagents should not contact with water, and the water bath will generate a lot of steam, and therefore can not use the water bath heating. 12 circular water bath nitrogen blowing instrument reference: Hangzhou Poly-Electronics Co., Ltd.
