Product Description:

FCD-10 oil-free vacuum pump has advanced design, compact and reasonable structure, small size, light weight, convenient movement, stable operation, high vacuum, low noise, high working efficiency and long service life. According to the needs of the operator, filter membranes with different materials and different filter pore sizes are selected to achieve the functions of removing impurities in the solvent, purifying and sterilizing. In chromatographic analysis, the solvent filtered by it can not only effectively extend the service life of the chromatographic column, but also because of its vacuum removal effect, it also significantly improves the data accuracy of the analysis system. It can be used directly with solvent filter, solid phase extraction instrument, multiple filter, vacuum drying oven, etc.

FCD-10 oil-free vacuum pump features:

1. Compact and reasonable structure, small size, high vacuum, low noise.

2. The pump is used in conjunction with a filter bottle, a multiple filter and a solid phase extraction device to achieve an ideal pumping effect.

3. It is suitable for pumping various liquids and decompressing and vacuuming containers. It is really an ideal negative pressure equipment for laboratory suction and vacuuming.

4. According to the needs of the operator, it can be matched with solvent filters, solid phase extraction devices and other equipment.

FCD-10 oil-free vacuum pump is an important filter supporting equipment to improve the filtration efficiency and strengthen the degassing effect. In order to ensure that the filter medium is not contaminated, oil-free diaphragm vacuum pumps are generally used. This type of pump forms a vacuum through the reciprocating movement of a rubber diaphragm. The vacuum pressure is generally about 0.08Mpa (single stage). The key to increasing the filtration speed is The exhaust volume per unit time and the flow index of the vacuum pump are particularly prominent when the filter volume is large and the medium viscosity is high.
