Descrizione del prodotto:
Settore dei prodotti Qualtech Tester Schopper Riegler is a professional drainage test equipment to measure the flow rate of diluted suspensions of pulp and a wide range of aqueous samples. The flow rate of pulp samples is equivalent to the freeness of pulp. Schopper Riegler test results are presented in ' °SR' in the range from 0°SR - 100°SR.
Questo Tester di libertà di Schopper Riegler is engineered for a very similar test application as the Tester canadese standard per la libertà di scorrimento in the paper production and it is the primary drainage test system to measure all types of pulp used to manufacture paper and cardboards, however, high test results measured with the Tester Schopper Riegler are presented in the low range on the Tester canadese standard per la libertà di scorrimento.
This Schopper Riegler Tester is designed and engineered offering a drainage chamber combined with a phosphor and bronze wire screen and a measurement chamber with a precision engineered and calibrated orifice mounted on a stainless steel support.
This Schopper Riegler Freeness Tester is very user-friendly, easy to clean and made of stainless steel offering a reliable performance and an ergonomic design.
This professional Schopper Riegler Freeness Tester is designed and engineered in accordance with international test standards including:
Schopper Riegler Pupl Drainage Tester – Features:
Il Schopper Riegler (SR) Test is a standardized method used to determine the drainability of pulp suspensions, which directly reflects the degree of refining of cellulose fibers. In this test, a defined volume of diluted pulp is poured into a chamber equipped with a precision screen. When the sealing cone is lifted, water drains through the screen while fibers form a temporary mat. The rate at which the filtrate passes through this mat is a sensitive indicator of fiber development, internal fibrillation, and fines content.
The test divides the filtrate into two paths: one portion flows freely into a graduated cylinder, while the remainder is diverted into the SR measuring chamber. The SR value corresponds to the volume retained in the measuring chamber, expressed in 'Schopper Riegler degrees'. A higher SR value indicates slower drainage and therefore a more highly refined pulp, while a lower SR value corresponds to faster drainage and less‑refined fibers. This makes the SR method particularly useful for monitoring refining efficiency and fiber treatment consistency in laboratory and mill environments.
Engineers rely on the SR test because it provides a fast, repeatable, and sensitive measure of fiber modification that correlates well with downstream papermaking behavior. Changes in SR values reflect variations in fiber flexibility, surface area, fines generation, and water retention — all critical parameters for sheet formation, strength development, and energy optimization in refining operations. The method is standardized under ISO 5267‑1 and TAPPI T227, ensuring global comparability and process control reliability.
