7. Frequently Asked Questions (FAQ)
Q1: How do I select the correct grade of cellulose filter paper for my application?
A: The selection depends primarily on the particle size you need to retain and the desired flow rate. For coarse precipitates, a faster, larger-pore paper is suitable. For fine particles or sterile filtration, a finer-pore, slower paper is required. Our technical team can assist you based on your specific sample type and process goals.
Q2: What is the difference between qualitative and quantitative filter paper?
A: Qualitative papers are for general separation where the filtered residue is not weighed. Quantitative (ashless) papers are acid-washed to have extremely low inorganic (ash) content, making them essential for gravimetric analysis where the residue is dried and weighed accurately.
Q3: Can your filter papers be used for sterile filtration?
A: Standard cellulose filter papers are not inherently sterile. They can be autoclaved for sterilization. For critical sterile applications, we recommend discussing your needs with us, as we offer specialized grades and can guide on proper validation procedures.
Q4: Do you offer private label or custom packaging?
A: Yes. As a flexible cellulose filter paper factory, private labeling and custom packaging (including bulk rolls, pre-cut sheets, or branded boxes) are core services we provide for our OEM and distributor partners.
Q5: What are your minimum order quantities (MOQs)?
A: We cater to a wide range of clients. MOQs vary depending on the product grade and customization level. We are happy to work with new partners, from sample requests to full container loads. Contact our sales team for specific details.
