Filter Papers
Quantitative 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.
Qualitative Filter Papers, wet strengthened
These filter papers are especially suitable for qualitative analyses.
These filter papers are especially suitable for qualitative analyses that require a low ash content.
Qualitative-Technical Filter Papers, smooth
These paper grades are generally used for analytical and technical purposes.
Qualitative-Technical Filter Papers, creped
These paper grades are generally used for analytical and technical purposes. They have a fast flow rate due to their structure.
Filter Boards for Filtration and Liquid Absorption
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.
Germination Test Papers
These paper grades are ideal for ensuring an optimal moisture content for the most diverse types of seeds and germination forms.
Surface Protection Papers
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. » more
Phase Separator Papers
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.
Diatomaceous Earth Filter Papers
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.
Sample Carrier Papers
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. » more
Non-Wovens
These non-wovens grades are generally used for the filtration of industrial liquids.
Weighing & Lens Cleaning Paper
Weiging Paper is ideal for analytical weighing of viscous, semi-crystalline or solid substances. Lens cleaning paper is soft and non-fluffing tissue paper made in silk for cleaning very sensitive surfaces such as optical glasses, lenses without scratching them.
Cellulose Extraction Thimbles
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.
Blotting Papers
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.
Chromatography Papers
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.
Glass Microfiber Filters
Binder free glass microfiber filters are suitable for analytical and gravimetric analyses. Glass microfiber filters with binders are generally used for the air and gas monitoring but also as prefilter
Quartz Microfiber Filters
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
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.
Reagent Papers
These reagent papers can be used to determine the presence of a certain substance in a sample.
