FAQs
What is this Sharkskin filter paper?
This is a qualitative wet‑strengthened filter paper (Grade 961) with a 50 cm diameter, designed for general laboratory filtration. Its creped surface and fast‑filtering grade help speed up filtration of liquids containing coarse or particulate solids, while its wet‑strengthened construction prevents tearing during use.
What does “wet‑strengthened” mean?
“Wet‑strengthened” refers to reinforcement of the cellulose fibers so the paper retains its integrity when saturated with liquid. This prevents tearing, wrinkling, or collapse during filtration, especially when filtering heavier suspensions or viscous solutions, making the paper more durable for routine lab use.
What does “fast filtering grade” indicate?
“Fast filtering grade” means the paper has larger pore size and surface structure to allow liquids to pass through quickly. It’s ideal when filtration speed is important and fine particle retention isn’t the priority, such as in routine sample preparation or coarse precipitate separation.
What size is this filter paper, and why does it matter?
This filter paper has a 50 cm diameter, providing a large surface area to increase filtration throughput. A larger diameter can reduce filtration time and handle greater liquid volumes before clogging, which helps efficiency in high‑volume or repetitive lab tasks.
What laboratory tasks is it used for?
It’s suitable for routine laboratory filtration, separating coarse suspended solids, and sample preparation prior to analysis. The combination of large surface area and fast filtration makes it useful in chemistry, environmental, and general lab settings.
