Frequently Asked Questions

Get answers to common questions about our membrane filters

What is the difference between hydrophilic and hydrophobic membranes?

Hydrophilic membranes (like PES, PVDF) attract water and are used for aqueous solutions. Hydrophobic membranes (like PTFE) repel water and are ideal for air/gas filtration or organic solvents.

Are your IV filters sterile?

We offer both sterile (ETO sterilized) and non-sterile options. Please specify your requirement when ordering.

Can you customize filter dimensions or pore sizes?

Yes, we provide OEM/ODM services with customizable diameters, pore sizes (0.1μm to 15μm), and housing materials.

What certifications do you have?

We are ISO 9001:2015 certified. Our products meet international standards for medical and laboratory use.

What is the minimum order quantity (MOQ)?

MOQ varies by product. For syringe filters, it's typically 1,000–10,000 pcs. Contact us for specific quotes.
