Housing and technology

Diam and pore size

Syringe filters with different pore size ratings are suitable for different applications. For example, for column systems using 3μm or larger size, a 0.45μm syringe filter is available. 0.2μm filter can be used for microbial filtration,(buffers, culture media). For turbid solutions can choose 1-5μm for pre-filtration and clarification.

Diam:4(mm),13(mm),25(mm),33(mm).
