FAQs

What is the Sharkskin 500 mm filter paper?

This Sharkskin filter paper is a large‑diameter (500 mm) qualitative lab filter made from super‑refined cellulose with a creped medium‑to‑slow flow rate. It’s designed for reliable filtration of liquids containing coarse or gelatinous precipitates, with durability and consistent performance in wet conditions.

What does “medium to slow grade” mean?

“Medium to slow grade” refers to the flow rate of liquid through the paper. This grade retains smaller particles while allowing liquid to pass steadily. It’s suited to applications requiring precise separation and clarity, rather than high throughput, making it ideal for detailed filtration tasks.

What materials is the filter paper made from?

The paper is made from super‑refined cellulose, which provides consistent fiber quality and strength in wet conditions. This material withstands weak acids and bases, resists tearing during filtration, and delivers consistent performance across repeated laboratory use.

How large is this filter paper, and why does it matter?

This paper has a 500 mm (50 cm) diameter, giving a wide filtration surface. Larger filters can handle greater volumes and reduce clogging during longer runs, improving efficiency and reducing the need for frequent paper changes in high‑volume or large‑batch filtration.

Where is this filter paper typically used?

It’s used in laboratory filtration, liquid clarification, removal of suspended solids, and pre‑analysis sample preparation. It’s also useful as a protective liner for filter press cloths in larger setups and for non‑lab technical filtration tasks requiring durability and reliability.
