Traditionally the grade is used in qualitative analytical separations for precipitates such as lead sulphate calcium oxalate hot.
Types of filter paper used in laboratory.
It is normally round in shape.
The functional principle of the filter paper is separating the substances through them.
Below are summaries of the grade properties and common uses.
This grade covers a wide range of laboratory applications and is frequently used for clarifying liquids.
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.
The basics and types of filter paper.
The filter paper is one of the common laboratory consumables in the labs.
Filter paper is a quantitative paper used for filtering and made of pure cellulose treated with hydrochloric and hydrofluoric acid.
The raw materials are different paper pulps the pulp may be from softwood hardwood fiber crops mineral fibers for high quality filters dissolving pulp and mercerised pulp are used.
Most filter papers are made on small paper machines for laboratory filters the machines may be as small as 50 cm width.
The paper is often crêped to improve porosity.

It is often made from cotton fiber and used to filter components.
Different types of paper are marked with numbers.
There are several basic types of laboratory filters.
Filter paper qualitative and quantitative filter papers for the clarification and purification of samples for analysis.
Laboratory filters are used to remove particulates from samples in laboratory scale applications.
They consist of a filter medium and housing or holder that constrains and supports the filter media in the sample s path.
Types of laboratory filters.
The filter papers may also be treated.
Available in a range of sizes counts grades and formats such as circles sheets and folded.
