Pulp Testing Equipment
Product Description
This instrument is used for determination of freeness of wood fibre ground wood and mechanical pulp. It measures the Canadian Freeness number which is a measurement of the drainage capacity of different pulp types.
It is a useful index of the amount of mechanical treatment given to the pulp With standard screen plate and Plexiglas measuring cylinder for CSF value.
3 grams of OD fibre pulp in aqueous suspension is drained through the fibre mat on a standard perforated screen plate during the test into a funnel provided with a bottom and side orifice.
The filtrate collected in specially graduated measuring cylinder from the side orifice is expressed as a CSF value corresponds to milliliter.
Product Specifications
Its Nozzle and screen plate are calibrated according to relevant standards. Two measuring cylinders are included.
