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.

Slightly more retentive than Grade 1 with a corresponding increase in filtration time (i.e., slightly slower filtration speed).
More absorbent than Grade 1. In addition to general filtration in the 8 μm particle size range, the extra absorbency is utilized, for example, to hold soil nutrient in plant growth trials.
Also used for monitoring specific contaminants in the atmosphere and in soil testing.
Nuclepore track-etched polycarbonate membranes are manufactured from high-quality polycarbonate film and have sharply defined pore sizes, high flow rates, and excellent chemical and thermal resistance.
The membranes have a smooth flat surface and exhibit very low levels of extractables.
Grade 41: 20 μm*
The fastest ashless filter paper, recommended for analytical procedures involving coarse particles or gelatinous precipitates (e.g. iron or aluminum hydroxides).
Also used in quantitative air pollution analysis as a paper tape for impregnation when
determining gaseous compounds at high flow rates.
