Syringe filters with prefilters used with glass microfiber and PP that have high dirt loading capacity. Additionally, the prefilters used have larger pores on the top surface (inlet side) compared to the pores on the bottom surface.This asymmetric pore structure further increases the dirt loading capacity of the prefilter.

We provide a range of syringe filters that contain built-in prefilters.These syringe filters are designed to make filtration easier for the user.Prefilters extend the useful life of the final membrane filter, enabling larger volumes to be filtered with reduced hand pressure.

You can choose an additional layer of PP membrane or glass fiber filters.
Using pre-filter can effectively block large particles as well as solve the problem of thick dense liquid filtration
