1. Applicable to Magen series single tube purification kit, up to 20 samples can be processed at the same time.
2. High sealing and high compression resistance can not only achieve negative pressure effect in low negative pressure environment, but also ensure no deformation in high vacuum state.
3. Made of corrosion-resistant high-purity materials for longer service life.
4. Translucent design,easy to observe the experimental process and prevent too much waste liquid from damaging the negative pressure pump system.
