<p>#CMT# #/CMT# The use of a disposable high density polyethene or polyethene small container in a grinding process for sample material reduces the chance of contamination of sample material. Each sample to be ground is placed in the grinding machine in a new small container. #CMT# : #/CMT# Through the "skilled" enclsoure of the small containe, using a two-half structure, the container is clamped during the grinding procedure and the sample material is not lost. The so-called grinding loss is thus very slight. #CMT#USE : #/CMT# As a disposable small container for use in the grinding process of sample material in environmental analysis investigation. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure displays a computer drawing of the equipment involved. 1 : Motor of grinding machine (14,000-30,000 rev./min.) with grinding blade at one end of the shaft 2 : small sample container 3 : Enclosure of container.</p> |
