VWR® Filter papers offer a wide range of ash-less filter paper for qualitative and quantitative analysis.

Supplier: VWR Collection

These highly pure filter paper grades are produced from cellulose fibers with an alpha-cellulose content of nearly 100%, in accordance with precise quality standards. The ash content is approximately 0.06%.

Supplier: Sartorius

These paper grades are used for analytical purposes that require a low ash content. They are essentially used for qualitative analyses.

Supplier: Sartorius

These qualitative filter papers are essentially used for analytical purposes and routine analyses, whenever no gravimetric analyses are required. They are wet-strengthened and can be used for pressure and vacuum filtration. They are made of refined pulp and linters with an >95% alpha-cellulose content, are very pure with an ash content <0,1%.

Supplier: Sartorius

These smooth filter papers are made of refined pulp and linters with more than 95% alpha-cellulose content. The ash content of these filter papers is between 0,1 and 0,15%.

Supplier: Sartorius

These filter papers are made of 100% cotton linters. They are guaranteed to be free of any residual acids and they have an extremely low percentage of ash content. As a result, these filters are virtually ash-free. All Sartorius ashless filter papers are characterised by high wet strength and high purity and are therefore especially suitable for quantitative analysis, Büchner funnels, pressure or vacuum filtration.

Supplier: Sartorius

These smooth filter papers are made of refined pulp and linters with more than 95% alpha-cellulose content. The ash content of these filter papers is between 0,1 and 0,15%.

Supplier: VWR Collection

Suitable for coarse precipitates such as aluminium hydroxide, cobalt carbonate, mercury iodide, magnesium hydroxide and more.

Supplier: VWR Collection

Useful for rapid filtrations where fine particle retention is not required.
