Title: Automated sampling and testing of milk samples esp. for germ count - by filling coded sample bottles mounted on a rotary plate transport system and transferring sample bottles to a smaller capacity bottle holder prior to analysis
IPC: G01N35/04
Filed: 1991-05-31

In the analytical laboratory the up to eg 72 numbered sample bottles in the transport container are warmed, shaken (mixed) and finally removed from the transport container for successive reading of the bottle code and removal of a sample from the sample bottle by a sampling needle in the analytical appts. Two rotary plate sample flask holders with different capacities are used in succession, a larger transport holder and a smaller analysis holder, whereby the larger holder can accommodate up to eg 72 bottles and the smaller holder can accommodate a max. of half this number of bottles. Only after transferring the sample bottles from the larger to the smaller sample bottle carrier in the analytical laboratory is the warming and shaking (mixing) of the sample bottle contents carried out with immediate passage to the analytical appts. with the smaller sample bottle carrier. Pref. sample bottles giving a questionable result are immediately transferred to an equally small sample flask analysis holder and they are then again warmed, shaken and immediately input to the analytical appts. Pref. the sample bottle capacity of the smaller analytical holder is only so large that with the last sample bottle passed from the container to the analytical appts. a still reliable analytical result can be obtained with the sampling needle of the analytical appts. (with or without stirring). USE/ADVANTAGE - Process is esp. useful for carrying out germ counts on milk samples and gives analytical results with reliable accuracy.
