(defined as the number of samples that must be tested per analyte) are required per PT event for most testing. CLIA required laboratories to be enrolled in an approved PT program as of Jan. 1, 1994; in 1995, CMS began to impose sanctions for those not enrolled (see Chapter 5). B. The QC requirements include control and calibration requirements

Used to crush aggregates, core samples and similar materials when a reduction in sample size is necessary. The crusher has a jaw opening of 100x60 mm and can produce from 100 to 400 kg of material per hour. The movement of the jaws can be adjusted from 2 to 18 mm. The crushed sample can be further reduced using the Hammer mill for laboratory.
Ball Mills are the most effective laboratory mills for rapid batchwise comminution of mediumhard, soft, brittle, fibrous, temperaturesensitive and moist samples down to the finest particle size. The comminution of the material to be ground takes place through impact and friction between the grinding balls and the inside wall of the grinding ...
No matter if your material samples are wet, dry, elastic, brittle, hard or soft, we have the laboratory mills to give you highquality results. Our mills can prepare samples for testing through grinding, homogenization and several other functions depending on the quality of the material.
A 11 basic Analytical mill Batch mill for 2 different grinding procedures: Impact grinding of hard, brittle or nonelastic grinding materials with highgrade stainless steel beater. This beater can be used for a Mohs hardness up to 6 (incl. with delivery).
