產品廣泛應用于過濾、樣品濃縮、固相萃取等裝置中，是實驗室重要的基礎設備。單級或雙級泵是通過橡膠膜片上下往復運動，引導氣流通過泵頭，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. 特點：features 1. 采用結實的鋁合金外殼，不銹鋼或塑料提手，使用輕便，功能全面。 Portability and versatility with a tough, aluminum cover and stainless steel or plastic handle. 2. 提供了一個潔凈的真空環(huán)境，不會對系統產生污染。 Provide a clean vacuum and won’t contaminate your system. 3. 獨特的皮膜設計減少磨損，延長工作壽命。 Unique flat diaphragm design reduces wear and tear for long service life. 4. 內設過熱自動保護裝置防止電機損壞，延長泵的壽命。 Built-in heat-triggered protector prevents motor damage and extends pump life.
