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

Offers fine particle retention and high flow rate, as well as good loading capacity.

Used for high-efficiency general purpose laboratory filtration, including water pollution monitoring of effluents, for filtration of water, algae and bacteria cultures, food stuff analyses, protein filtration, and radioimmunoassay of weak ß emitters.

Recommended for gravimetric determination of airborne particulates, stack sampling, and absorption
methods of air pollution monitoring.
