产品广泛应用于过滤、样品浓缩、固相萃取等装置中，是实验室重要的基础设备。单级或双级泵是通过橡胶膜片上下往复运动，引导气流通过泵头，形成真空状态。无油真空泵提供了完全洁净的真空环境，泵体本身无需保养，而且不会产生任何污染物。
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.
