Cutting Mill grinds biological samples.

Model SM 100 grinder processes organic compound, metal, and textile samples, up to 60 x 80 mm, into fineness of less than 1 mm. Batch size ranges from 5 to 30 liters. Various screens and hoppers allow for adaptation to individual applications. Samples suitable for processing include: bones, cellulose, tissue, compost, silage, corn, cereals, grain, hay, alfalfa, sugar beets, tobacco, roots, wood,...

Divider/Feeder provides representative samples.

PT 100 Sample Divider ensures that sample represents entire bulk instead of random samples taken out of buckets with spatulas or spoons. Rotating rifflers spilt up to 5 L of inhomogeneous samples with wide particle size distribution into 6, 8, or 10 representative sub-samples. DR 100 Vibratory Feeder ensures that divider is centered over inlet hopper for no-loss feeding. Feed rate is controlled...

Ball Mill grinds to sub-micron dimensions.

PM 400 Planetary Ball Mill processes up to 8 samples without contamination, grinds material to sub-micron fineness, and has maintenance-free drive. Grinding sets are available in 4 sizes and 6 different materials. Superimposed motion of grinding jars, relative to central wheel, achieves high grinding efficiency. Generated energies by impact and friction of grinding media (beads) permit mixing,...

Test Sieves meet or exceed ISO standards.

Corrosion-resistant test sieves are made of high-alloy 316L steel. One-piece body includes individual lasering of mesh width. Resistant-welded sieve-frame construction provides permanently stretched wire gauze. Groove- and solder-free transition eliminates cross contamination and makes cleaning easy. Each sieve comes with seal ring for tight sieve stacks and low-noise operation.
