Producent: Whatman products (Cytiva)

Opis: Whatman Grade 54 hardened low ash quantitative filter paper for Büchner funnel and Hirsch funnel filtration enables fast vacuum suction filtration for recrystallization applications.

Producent: Whatman products (Cytiva)

Opis: Cytiva's Whatman Grade 52 is a general-purpose filter paper for quantitative analysis in Büchner funnel and other vacuum filtrations. The acid-hardened surface and low ash content enable efficient precipitate recovery.

Producent: Whatman products (Cytiva)

Opis: Cytiva's Whatman Grade 43 filters support inorganic analysis and other forms of instrumental analyses. The low ash content also makes Grade 43 appropriate for gravimetric analyses requiring sample combustion.

Producent: Ahlstrom-Munksjö

Opis: Ahlstrom-Munksjö manufactures a series of extremely high purity, acid washed filter papers designed for use in analytical and gravimetric analysis. The quantitative grades are manufactured from top quality cotton linters using ultra-pure, deionised water and are further treated with dilute acid to remove any remaining organic and inorganic impurities. All quantitative grades are manufactured in a strictly controlled environment that ensures high uniformity and high purity from filter to filter.

Producent: Sartorius

Opis: 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.

Opis: Filter paper, quantitative, 28 mm

Producent: Bel-Art Products, a Part of SP

Opis: These heavy bond grade filter paper discs are custom-sized to fit table-top Buchner funnels and have a thickness of 0,30 mm.

Producent: MACHEREY-NAGEL

Opis: These quantitative filter papers are made from refined pulp and linters. They are purified in a highly developed clean-up process to remove organic and inorganic impurities. This ensures a low ash content of <0,01 %. They are consistent performance and give safe results in gravimetric analyses.

Producent: MACHEREY-NAGEL

Opis: These wet strengthened hard smooth filter papers are made of refined pulp and linters and have a low ash content. They are often used for quantitative routine procedures and for analytical gravimetric applications.

Producent: PRAT DUMAS

Opis: These papers are made of very pure cellulose and are washed in acids. They are designed for the quantitative analyses of routine applications and wet strengthened.

Producent: PRAT DUMAS

Opis: The ashless papers are manufactured with a very pure cotton cellulose base. They are purified with acid to reduce the amount of mineral material such as silicon, aluminium or magnesium oxides as far as possible. The residues of the paper after calcination are reduced to negligible quantities and do not affect the results of the qualitative analysis.
