Laboratory filtration from clarification over sterile filtration to ultrafiltration. Choose membrane prefilters for particle and bioburden reduction. Sartorius Stedim Biotech sterile filters are suitable for the safe filtration of air | gas and liquids. Applications for our ultrafilters are nucleic acid concentration, protein concentration and fractionation with high recoveries.
The grade Q3400 is made of 100 % high-purity quartz microfibers only and pre-heated to guarantee excellent weight and dimensional stability. The filters are especially suitable for emissions monitoring at temperatures of up to 900°C and wherever filters of the highest purity are needed. A trace element analysis is performed for each single lot and its certificate of analysis is available on demand.
This smooth yellow paper grade satisfies the requirements for the determination of dermination capability according to ISTA (International Seed Testing Association) and is ideal for ensuring optimal moisture content for the most diverse types of seeds and germination forms. The pH ranges between 6.0 and 7.5, it is wet-strengthened and the special structure prevents fine seed roots from growing through the paper.
The grade C 350L is a very pure paper made of cotton linters only.
Filter board for the absorption of liquids.
This paper grade is generally used for analytical and technical purposes. It has a fast flow rate due to its structure.
