Filter paper

Information about the type and use of various grades of filter papers can be found in section 9.11.4 of the CLEAPSS Laboratory Handbook.

Filter pumps

The use of traditional water-operated filter pumps for vacuum filtration and for drawing air through solutions is covered in section 10.6.4 of the CLEAPSS Laboratory Handbook.

It is strongly recommended that this is referred to before purchasing or using such pumps – it may not be possible or appropriate to use this type of equipment in your school or college.

Alternative means of carrying out vacuum filtration and drawing air through solutions are suggested in this section of the Laboratory Handbook.
