Up to 17 fractions (16 test sieves plus collecting pan with a height of 25 mm), 9 fractions (8 test
sieves plus collecting pan with a height of 40 mm or 50 mm), or 7 fractions (6 test sieves plus
collecting pan with a height of 65 mm) can be clamped.
NOTICE A high number of test sieves can significantly increase the total weight of the load
(sieve stack and sample material). Make sure not to exceed the maximum payload of 20 kg.
Different sieve clamping units and lids are available for the test sieves.
The following sieve clamping units are available for test sieves with an outer diameter of
305 mm (12") and 400 mm:
"standard"
Ø 305 mm
