產(chǎn)品廣泛應(yīng)用于過濾、樣品濃縮、固相萃取等裝置中,是實驗室重要的基礎(chǔ)設(shè)備。單級或雙級泵是通過橡膠膜片上下往復(fù)運(yùn)動,引導(dǎo)氣流通過泵頭,形成真空狀態(tài)。無油真空泵提供了完全潔凈的真空環(huán)境,泵體本身無需保養(yǎng),而且不會產(chǎn)生任何污染物。
These pumps are widely used for applications including filtration, sample concentration, solid phase extraction. They are the important basic instruments in the lab. One-stage or two-stage pumps feature up and down movement of flexible diaphragm during the mechanical stage which induces a flow of gas through the pump head, generating a vacuum. Thus they can provide a clean vacuum over the entire vacuum range. Dry pumps require little maintenance and don’t generate any waste material.
