Portable oil-free diaphragm vacuum pump

There are two options for vacuum pumps: portable oil-free diaphragm vacuum pump and two-stage rotary vane vacuum pump, mainly used in solid phase extraction experiments. Product description: NAI-DP-01 Portable oil-free vacuum pump can be equipped with solvent filters, multiple filters, and negative pressure devices required for solid phase extraction Vacuum pump is an important filtration equipment that improves filtration efficiency and enhances degassing effect. 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 motion of rubber diaphragms, and its vacuum pressure is generally around 0.08Mpa (single-stage). The key to improving the filtration speed is the exhaust volume per unit time and the flow index of the vacuum pump. It is particularly prominent when the filtration volume is large and the viscosity of the medium is high, and particles clog the filter membrane. Main features: 1. Compact and reasonable structure, small volume, high vacuum degree, and low noise. 2. This pump, when used in conjunction with filter bottles, multiple filters, and solid-phase extraction devices, can achieve ideal pumping effects. 3. Suitable for suctioning various liquids and reducing pressure and vacuuming containers, it is truly an ideal negative pressure equipment for laboratory liquid suction and vacuuming. 4. According to the needs of the operator, it can be matched with equipment such as solvent filters and solid-phase extraction devices.
