Buying Guide

Match membrane material to solvent

Choose PTFE for aggressive organic solvents and PES for aqueous solutions and protein work to avoid membrane degradation or sample loss

Select the correct pore size

Use 0.22 µm for sterilization and fine particulate removal, and 0.45 µm for routine clarification where sterility is not required

Consider diameter and syringe compatibility

25 mm and 33 mm filters fit different syringe volumes; confirm diameter (25 mm vs 33 mm) matches your syringe or filtration setup to avoid leaks or wasted sample

Assess pack size versus usage rate

Bulk packs (e.g., 50–100 per pack) lower per-filter cost for high-throughput labs, while smaller packs suit intermittent use to limit storage and contamination risk

Check sterility and intended use

Choose explicitly sterile filters when working with cell culture or microbiological samples; non-sterile filters are acceptable for many HPLC and general prep tasks
