A prepleated filter used for many routine analytical applications in different industries (e.g., particle separation from food extracts or filtration of solids from digested environmental samples, e.g., for ICP/AAS analysis).

Supplier: Ahlstrom-Munksjö

These quantitative ashless hardened filter papers are recommended for use where a high purity is required for quantitative analysis.

Supplier: Whatman products (Cytiva)

A thin paper with great wet strength and a very high flow rate. Frequently used in technical applications such as the filtration of viscous liquids and emulsions (e.g., sweetened juices, spirits and syrups, resin solutions, oils, or plant extracts).

Supplier: Ahlstrom-Munksjö

Boards which by their filtration properties are keyed to specific applications as well as to industrial filtration processes.

Queste carte da filtro sono ottenute da pasta di legno raffinata e linter di cotone con una percentuale di alfa-cellulosa superiore al 98%. Sono garantite esenti da acidi residui e hanno un contenuto di ceneri estremamente basso. Pertanto, questi filtri sono praticamente privi di ceneri. Tutte le carte da filtro Sartorius prive di ceneri si caratterizzano per un'elevata resistenza al bagnato e un'elevata purezza e sono quindi particolarmente adatte per analisi quantitative, imbuti di Büchner, filtrazione a pressione o sotto vuoto.

Grade 470 papers are made of cellulose and diatomaceous earth and offer a much better separating capability than pure cellulose papers at the same rate of filtration.

Supplier: Whatman products (Cytiva)

Cytiva's Whatman Grade 44 quantitative paper is a thin version of Grade 42 ashless paper. The thinness reduces the overall ash content, making Grade 44 well suited for analyses relying on ash-free dry weight.

Supplier: Ahlstrom-Munksjö

These quantitative ashless hardened filter papers are recommended for use where a high purity is required for quantitative analysis.

Creped cellulose filter papers with good retentivity at a relatively high filtration speed. They are used for the clarifying filtration of dried beet pulp extracts or beet juice after the addition of lead acetate for subsequent polarimetric sugar determination. They are specifically designed for the Venema unit (lead acetate method).

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%. They are used for routine analyses like clarification, determination of substances, but also as discs with a centre hole for technical applications. Grades with a wet burst resistance >30 kPa are referred to as wet-strengthened and are therefore suitable for pressure or vacuum filtration.

Carta da filtro per analisi quantitative

Supplier: Sartorius

This phase separating paper is impregnated with stabilised silicon, thus rendering it hydrophobic and it retains water, but allows solvents to flow through. The flow stops automatically when the entire solvent has passed through, this eliminates the need to use separating funnels.

Supplier: Ahlstrom-Munksjö

The following filter papers fulfill specific technical requirements corresponding to the requirements mentioned overleaf. Embossed filter papers have a larger surface area and, therefore, correspondingly shorter filtration times. They show a very homogenous and fine pore structure.
