Sub-division of laboratory sample comprises delivering sample from source onto turntable sub-divider and subjecting to oscillating action

摘要

In a process to sub-divide a laboratory sample (12) into portions, the sample is delivered from a source (2,3) onto a rotating sample-divider (1). The divider has a number of sample holders (52) of approximately. the same volume. The rotating motion of the sample holder is especially overlain by an oscillation. An Independent claim is also included for the apparatus for the above process, comprising a drive (40) and an oscillation generator (70). A sample source (2,3) is fixed to an oscillating and rotating sample holder (15). The sample supply source comprises a funnel (3) feeding grooves (2) to a sample holders (52). The sample holders are held in a spring (22) mounted turntable fitted to a socket (16).
