FAQ

What does “ashless” mean for filter paper?

“Ashless” indicates that the paper contains less than 0.01% inorganic residue after combustion. This low ash content prevents interference with analytical measurements, making the paper ideal for quantitative work such as gravimetric analysis.

Can this filter paper be used with standard laboratory funnels?

Yes, the 90mm round diameter is designed to match common funnel sizes, allowing seamless integration into existing laboratory setups without the need for adapters.

Is the slow flow rate suitable for all types of filtration?

The slow flow rate is optimized for applications where precise particle retention is essential, such as gravimetric analysis and sample preparation. For rapid bulk filtration, a different filter grade may be more appropriate.

How should the filter paper be stored to maintain its performance?

Store the filter paper in a cool, dry place away from direct sunlight. Keep the packaging sealed until use to protect the sheets from moisture and contaminants.

What support does GSC International provide if I encounter an issue?

GSC International offers a dedicated technical support team reachable via phone or email. Customers can also benefit from a straightforward return policy if the product does not meet the expected specifications.
