Qualitative Filter Papers-Grade 5: 2.5μm

Whatman chromatography paper media are made from specially selected cotton cellulose.

They are rigorously quality controlled for characteristics important to the chromatographer and to ensure uniformity within
the grade.

Features and benefits
• Pure cellulose produced entirely from the highest quality cotton linters
with no additives of any kind
• Manufactured and tested specifically for chromatographic techniques –
this ensures the wicking capability and uniformity of capillary action that
are important in chemical separations
• Also widely used in protein and nucleic acid blotting

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.
