WET-STRENGTHENED MED FILTER PAPERS 90MM

Wet-strengthened filter papers from Johnson? are manufactured from a majority of alpha-cellulose. The smooth surface allows a fibre free filtration. They feature a high wet strength and can also be used in the filtration of strong alkaline or acid solutions. Due to their high mechanical strength, they are suited to applications where the residue is removed from the filter, for example with a spatula or jet of water. They are grade 321 & have medium flow properties.
