L&W CSF Tester

Are you looking for support or purchase information?

L&W CSF Tester is designed to give a measure of the rate at which a dilute suspension of pulp may be dewatered. The drainage rate has been shown to be related to the surface conditions and swelling of the fibres. It is also a useful index of the amount of mechanical treatment given to the pulp. 

L&W CSF Tester consists of a drainage chamber and rate measuring funnel which are supported in a bench top mounting stand or (optional) wall mounting. The drainage chamber is a metal cylinder which contains a perforated brass screen plate which has been calibrated to give the proper flow. The top and bottom lids of the container are opened by a light pressure on the release handles, and are both fastened to swivel arms mounted to the stand.
