Perforated Test Sieves – High Test Precision, Strength, Durability
Perforated test sieves, available in diameter 450 mm, 400 mm, 300 mm and 75 mm with stainless steel frames and perforated stainless steel bottom, are suitable for precision testing and abrasive sorting. In addition, our test sieves products conform to ISO 3310 standard. With accurate test precision and high strength, in most of circumstances, perforated test sieves are widely applied to all kinds of laboratory sampling and particle size analysis. Because of extensive applications, our perforated test sieves also can be used in food, chemical, pharmaceutical, building, abrasive and metallurgy fields.
Note: We can provide brass perforated test sieves for improving aesthetic appearance.
Generally, perforated test sieves can be divided into four types according to hole shapes:
PTS-01: Perforated test sieves with round holes can be used in metallurgy, abrasive, construction and research lab fields.
PTS-02: Perforated test sieves with square holes can be used as grain screening in food making field.
PTS-03: Perforated test sieves with slotted holes can meet your requirements of accurate test precision.
PTS-04: Perforated test sieves with oval and slotted holes can increase area and speed of solid screening.
