Retsch, Inc.: Sample Divider, Vibratory Feeder Instruments
April 1, 2002
Retsch, Inc. recently launched its most advanced line of sample divider and vibratory feeder instruments to address many of the problems faced by laboratory professionals involved in taking random samples. The PT 100 sample divider ensures that important decisions regarding production adjustment are based on samples perfectly representing the entire bulk, instead of random samples taken out of buckets with spatulas or spoons. Rotating rifflers like the PT 100 are the most accurate systems available to split up to 5 L of inhomogeneous samples with a wide particle size distribution into 6, 8, or 10 representative sub-samples. The samples are collected in laboratory bottles attached to the divider with a convenient "snap fit" system. Due to the modular design, the dividing heads are easily interchangeable. The DR 100 vibratory feeder forms a secure and integral part of the divider in order to ensure that it is perfectly centered over the inlet hopper for no-loss feeding. The feed rate is controlled by the sample divider via an interface.
