Cellulose extraction thimbles are produced from high-quality alpha cellulose cotton
linter and have excellent mechanical strength and retention.
Standard single thickness thimbles have a wall thickness of approximately 1 mm
(10.0 μm nominal particle retention).
Price range: Rs.10,057.50 through Rs.10,282.50
CompareDouble thickness thimbles have a wall thickness of approximately 2 mm (6.0 μm
nominal particle retention) for applications where higher retention and increased
wet or dry strength, or rigidity are required.
The high purity of the materials ensures reliable and reproducible analytical results.

Combines fine particle retention with good flow rate.
The standard filter in many
parts of the world for the collection of suspended solids in potable water and natural
and industrial wastes.
Fast and efficient clarification of aqueous liquids containing
low to medium levels of fine particulates.
Widely used for cell harvesting, liquid scintillation counting, and binding assays where more loading capacity is required.
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.
Grade 50: 2.7 μm*
Retention of very fine crystalline precipitates.
The thinnest of all Whatman filter papers with a slow flow rate, these filters have a hardened and highly glazed surface, which also keeps the paper free from loose surface fibers.
Highly suitable for
qualitative or quantitative filtrations requiring vacuum assistance on Büchner
or 3-piece filter funnels.
Very strong when wet and will withstand wet handling and
precipitate removal by scraping.
In the electronics industry, the virtual absence of
fiber shedding is utilized in carriers for integrated circuits.
This grade is also available in Smear Tab format for wipe testing (e.g. testing of
surfaces for radionuclide contamination).
