Investigation of Cleaning Procedures for Agate Mortars and Plastic Tubes with the Aid of a Radioactive Tracer

Volume 20, Number 4 (Aug. 1966) Page 244-246

Havre, Gustav N.

Cleaning of agate mortars and plastic vials in the Wig-L-Bug mixer mill was studied by radioactive-tracer technique using 32P as sodium orthophosphate as a tracer. It was found for agate mortars that cleaning with aluminia followed by acid is adequate for preventing contamination of the next sample. Plastic vials used in the Wig-L-Bug mixer are difficult to clean and can hardly be reused more than once.
