Filter Papers
»
These filter papers are especially suitable for quantitative analyses, Buechner funnels, pressure or vacuum filtration.
They are made of refined pulp and linters with over 98% alpha-cellulose content, are characterized by high wet strength and are ash-free.
»
These filter papers are especially suitable for qualitative analyses.
»
These filter papers are especially suitable for qualitative analyses that require a low ash content.
»
These paper grades are generally used for analytical and technical purposes.
»
These paper grades are generally used for analytical and technical purposes. They have a fast flow rate due to their structure.
»
These paper grades are used for filtration of cooking and transformer oils, as absorptives of human serum and as base paper for further impregnation with certain reagents.
»
These paper grades are ideal for ensuring an optimal moisture content for the most diverse types of seeds and germination forms.
»
The grades LabSorb and LabSorb Ultra are highly absorptive papers coated on one side with polyethylene that can be used as surface protection and for many other applications.
»
This special paper separates aqueous from organic phases. The grade 480 is impregnated with a stabilized silicon, thus rendering it hydrophobic. It retains water and allows solvents to flow through.
»
These filter papers made of cellulose and diatomaceous earth have a much better separating capability than pure cellulose papers at the same rate of filtration.
The grade 470 quickly retains the finest particles at high flow rates.
»
The grade TFN is made from high-purity cotton linters and is highly absorbent. It is used to absorb and transport human bodily fluids such as capillary blood, urine and saliva.
»
These non-wovens grades are generally used for the filtration of industrial liquids.
»
The cellulose extraction thimbles are especially suited for all routine extractions. They are manufactured from cotton linters with a high alpha-cellulose content and are thermally stable up to 100°C. The inner diameter, outer length, round bottom and wall thickness are defined according to the norm DIN 12449.
»
The glass microfiber thimbles are especially suited for critical extractions. They are manufactured from 100 % borosilicate glass and are thermally stable up to 500°C. The inner diameter, outer length, round bottom and wall thickness are defined according to the norm DIN 12449.
»
The quartz microfiber thimbles are especially suited for emission monitoring. They are manufactured free of glass fibers and binding agents and are thermally stable up to 900°C. The inner diameter, outer length, round bottom and wall thickness are defined according to the norm DIN 12449.

Sartorius supplies four grades of blotting papers. Their extremely smooth surface and relatively high thickness provide them with absorption properties and most superior uniformity across the entire contact area in the blotting transfer system.
»
These filter products are made of cotton linters with more than 98 % alpha-cellulose content and < 0.04 % ash content; They are very absorbent and available in different weights, thickness and capillary rise.
»
Binder free glass microfiber filters are suitable for analytical and gravimetric analyses. They are also used as prefilter.
»
Glass microfiber filters with binders are generally used for the air and gas monitoring but also as prefilter.
»
Quartz microfiber filters are especially suited for emission monitoring at temperature of up to 950°C and wherever filters of the highest purity are needed.
They are free of glass fibers and binding agents.
»
pH papers for an easy and fast pH determination with an accuracy sufficient for nearly all routine pH tests.
»
For accurate determination of the pH in water samples and for adjusting the pH of a sample during analysis.
»
These reagent papers can be used to determine the presence of a certain substance in a sample.
