FAQ

What makes your cellulose filter paper high quality?

Our status as a high quality cellulose filter paper manufacturer is defined by premium alpha cellulose, strict pore size uniformity, and low ash content, verified through independent lab testing.

Can I get custom sizes or grades?

Yes, we offer bespoke manufacturing for specific pore sizes, diameters up to 500mm, and sheet dimensions tailored to your equipment.

Is it suitable for sterile applications?

While naturally antimicrobial-resistant due to purity, we recommend autoclaving or gamma irradiation for sterile needs; consult our technical team.

How does it compare to quantitative ashless filters?

Our Grade 5 and 6 match Whatman No. 42 standards, with equivalent ashless performance for ignitions up to 900°C.

What packaging options are available?

Standard: 100 circles/box, 25 sheets/pack; bulk: 500m rolls. All vacuum-sealed for moisture protection during global shipping.

Do you provide samples?

As a reliable high quality cellulose filter paper manufacturer, we offer free samples for qualified B2B inquiries to test compatibility.

What is the shelf life?

Indefinite when stored in dry conditions; our papers retain properties for years without degradation.
