Frequently Asked Questions (FAQ)
Q1: What factors influence the glass fiber filter paper price?
A: The price is primarily determined by the specific grade (pore size and thickness), order quantity, and any custom specifications (e.g., special dimensions or packaging). Bulk purchases typically benefit from significant per-unit cost reductions. The purity level of the borosilicate glass and the manufacturing tolerances also contribute to the value proposition.
Q2: Can this filter paper be used for sterile filtration?
A: While glass fiber filter paper is excellent as a pre-filter to extend the life of final sterile membrane filters, it is not rated as an absolute sterilizing grade filter on its own. For sterile filtration, it should be used in conjunction with a validated 0.22 µm or 0.45 µm membrane filter.
Q3: How do I select the correct pore size for my application?
A: Selection depends on the size of the particles you need to retain and your desired flow rate. A smaller pore size (e.g., 0.7 µm) provides finer filtration but may flow slower. For general clarification with high solids loading, a 1.5 µm or 2.0 µm paper is often ideal. Our technical team can provide specific recommendations based on your sample type.
Q4: Is the paper suitable for ashing in a muffle furnace?
A: Yes, this is one of its key advantages. Our binder-free glass fiber filter paper has an exceptionally low ash content and can withstand temperatures up to 500°C, making it perfect for gravimetric analysis where the filter and captured residue are weighed before and after ignition.
Q5: Do you offer samples for testing?
A: Absolutely. We encourage potential customers to test our filter paper against their current standard. Contact our sales team to request sample sheets of specific grades to validate performance in your application before placing a larger order.
