The nitrogen blowing instrument of Zhengzhou Baojing Electronic Technology Co., Ltd. blows nitrogen to the surface of the heated sample quickly, continuously and controllably to achieve rapid concentration of a large number of samples. By blowing nitrogen into the sample, increasing the surrounding air flow and raising the temperature can cause the solvent in the sample to evaporate quickly. Using a nitrogen blower instead of a commonly used rotary evaporator for concentration can concentrate dozens of samples at the same time, greatly shortening sample preparation time, and is time-saving, easy to operate, and fast.
Structure of nitrogen blower:
Nitrogen blower consists of chassis, center rod, sample positioning frame, gas distribution system, etc. The test tube is fixed by the positioning frame spring and the tray, and the sample position is numbered. The gas reaches the gas distribution system through the adjustable flow meter, and then passes through the elastic hose to the needle valve tube at each sample position. The needle valve tube can be adjusted up and down according to the size of the test tube and the amount of solvent. Finally, the gas is blown from the needle to the surface of the solution, causing the solvent to quickly evaporation.
Performance characteristics of nitrogen blowing instrument
. Baojing's nitrogen blowing instrument has the exclusive right to trademark, any counterfeiting will be investigated
.Maximum number of samples:, controllable range:
3. Round structure, the sample holder can be rotated, the operator can take the sample from the front, easy to operate. It is suitable for test tubes, Erlenmeyer flasks, centrifuge tubes, etc. and each sample position is numbered to facilitate experimental recording.
. Test tube size Ф - Internal liquid volume ~ Host overall size Ф
. Use Baojing Technology needle valve to control the nitrogen flow rate and switch of each sample position. Each air channel can be controlled simultaneously or independently, and the lifting height can be Freely adjust according to the height of the test tube
. Each channel is equipped with a flow adjustment device, making flow control easier
. Low nitrogen consumption, sample timing range ~/normally open, countdown display
. The circular constant-temperature water bath provides gentle heating, and the LCD displays the water bath temperature: room temperature + ~ ℃, optional thermometer monitoring
The bottom is equipped with a ring spring support device, which can easily lift the sample holder, and the needle valve tube can be adjusted up and down freely, and the lock Tight and convenient
. Nitrogen flow needle valve control, easy and comfortable, gas flow ~/, gas input range ~ gas output range ~ air inlet (outer diameter)
. Round water bath, CNC constant temperature display, It has an anti-dry burning alarm function
3. Air guide needle: stainless steel, length
. Made of colorless and odorless transparent silicone tube, stainless steel, chrome-plated copper, and hard aluminum materials. All parts are resistant to organic solvents
/> .Compact size, occupying the least space in the fume hood. When concentrating toxic solvents, the entire system can be placed in the fume hood
