Qualitative Filter Papers-Grade 4: 20-25μm
10 in stock
Extremely fast filtering with excellent retention of coarse particles and gelatinous
precipitates such as ferric hydroxide and aluminum hydroxide.
Very useful as a rapid filter for routine clean-up of biological fluids or organic extracts during analysis.
Used when high flow rates in air pollution monitoring are required and the collection of fine particles is not critical.
Available prepleated as Grade 4V.
Price range: Rs.1,057.50 through Rs.2,355.00
CompareCellulose filters are used in qualitative analytical techniques to determine and identify materials.
Prepleated qualitative filters are available, which give improved flow rate and increased loading capacity compared to equivalent flat filters.

Lens Cleaning Tissue
Lenses and other optical surfaces made from glass, quartz or plastic can be easily
scratched if you do not clean them with a very soft surface.High-quality Whatman
lens cleaning tissue provides the solution. The tissue is chemically pure and free
from silicones and other additives.Most importantly, it can be relied on to safely remove surface moisture and grease.
