Canadian Standard Freeness Tester (CSF)

Product line: S41510

For measuring the rate of drainage of pulp suspensions and expressing it in terms of Canadian freeness. The drainage chamber and filling chamber are mounted on a robust stainless steel frame. The filling chamber has a calibrated perforated screen plate at its lower end and drains into the spreader cone. It is closed from above and below by a cover. The upper cover is equipped with an air valve, which is used to start the process. The spreader cone drains into a calibrated nozzle and a drainage pipe mounted on the side.

Test description
The pulp sample (3 g pulp), prepared with the standardized disintegrator, is poured into the filling chamber with the bottom closed. The cover and air valve are both closed and then the bottom cover is opened. Since no air can enter the filling chamber, the pulp suspension remains in the filling chamber until the air valve is opened. The suspension falls through the perforated screen leaving a fibre mat behind while the filtrate drains through the spreader cone into a measuring beaker. Within the spreader cone there is a calibrated nozzle that allows only a small amount to flow through. The excess liquid runs through the side drain pipe into another measuring beaker.
