HD-D24SY
Introduction：
Round Water Bath Nitrogen Evaporator concentrates sample solutions quickly and oxygen-free by nitrogen blowing with 360-degree rotation. Widely used for food safety, pharmaceutical and pesticide residue testing....
The round water-bath nitrogen concentrator uses purge-and-trap technology and can simultaneously heat samples under controlled temperature. Nitrogen and other inert gases are blown quickly, controllably and continuously onto the sample surface to achieve rapid oxygen-free concentration of the sample solution. This method is time-saving, convenient and accurate, and is widely used in food safety, pharmaceuticals, pesticide-residue testing, clinical pharmacokinetics and other fields.
The round water-bath nitrogen concentrator is suitable for test tubes, conical flasks, centrifuge tubes and other containers of different specifications.
Sample positions: 12 or 24; the sample rack is fixed and positioned by spring test-tube clamps, and each sample has a digital number.
The test tubes are fixed in position by spring test-tube clamps and a support plate, and their height can be adjusted freely.
Freely lifting needle-valve tubes: according to the test-tube size and solvent volume, each gas-guide tube can be lifted independently to a suitable height, and the adjustable needle valve can control the gas flow.
Round structure, rotates freely, convenient for the sample rack to enter and leave the water bath; convenient to operate.
Intelligent digital temperature controller with timing and dual digital display; adopts PID technology and can realize over-temperature alarm and dry-burn protection.
All parts of the round nitrogen concentrator are made of stainless steel, resistant to acid, alkali and organic solvents.
Regulating valve: ensures good air tightness and durability.
When concentrating toxic solvents, the whole system can be placed in a fume hood.
