Sand filter device vegetable borosilicate glass, uniform wall thickness, no bubble glass smooth and transparent, fast flow, pressure and sealing performance.
Vacuum filtration is a common laboratory equipment, in the chromatographic analysis, for the removal of the column life and the accuracy of the system detection of impurities, has an important role. In the filtration process it is the liquid degassing effect is also obvious. The equipment with different purposes of the filter membrane has been applied in the weight analysis, chromatography, colloid separation and other tests.
This series of single-stage vacuum pump, using direct-overall design, to make products more compact, lightweight and reasonable. Using a large starting torque, for a special design for a low-temperature environment, to ensure that in the case of low ambient temperature in winter boot normally.
