MM-70 Master-Matched Sieves are ASTM E11 8in diameter stainless steel or combination sieves from No. 8 (2.36mm) to No. 325 (45μm) with openings that closely match a master set of sieves in Gilson’s reference laboratory. Master-Matched Sieves are verified to meet ASTM E11, then performance selected using NIST traceable Standard Reference Materials to correlate with the master set. Each sieve is performance tested to ensure it yields ±2.5% by weight of the value of the master sieve. Order this model MM-70 in addition to each sieve purchased.
