Sintered glass filter

Construction of Sintered glass filter

The sintered glass filter is made of borosilicate glass finely powdered, sieved, and particles of the designed size are separated. It is then packed into a disc mould and heated to a temperature at which adhesion takes place between the particles. The disc is then fused to a tunnel of suitable size and shape.

Working of Sintered glass filter

These filters are available in different pore sizes. Hence the funnel with a sintered filter is numbered according to the pore size. The filtration is carried out under reduced pressure.


1. It is used for bacterial filtration.

2. These are available in stainless steel which has greater mechanical strength.

3. These are liable to attack by solution passing through them.
