Types of filter paper used in laboratory.

This grade covers a wide range of laboratory applications and is frequently used for clarifying liquids. The most widely used filter paper for routine applications with medium retention and flow rate. Available in a range of sizes counts grades and formats such as circles sheets and folded. Different types of qualitative whatman filter paper their properties the most common qualitative paper grades are 1 6 595 597 598 and 602 which have applications across multiple industries.

They consist of a filter medium and housing or holder that constrains and supports the filter media in the sample s path. It is often made from cotton fiber and used to filter components. The filter papers may also be treated. Qualitative bears marking 595 or 597 and quantitative 589 or 590.

The functional principle of the filter paper is separating the substances through them. Most filter papers are made on small paper machines for laboratory filters the machines may be as small as 50 cm width. Throughout the different stages of chromatography laboratory filter paper plays a huge role in separation and purification processes these filtration products are highly useful in solvent filtering cellulose analysis as well as a number of industrial applications and are a must have for any lab or industrial process that involves separation and purification.
