Common questions
Why can't a rubber stopper be used for volatile poison cases?+
Volatile poisons such as alcohols or certain solvents can be absorbed by or react with rubber, altering the sample or allowing loss of the analyte, so an inert screw-cap closure is required to preserve the specimen accurately.
Why is plastic excluded specifically for aluminium phosphide cases?+
Aluminium phosphide releases phosphine gas on contact with moisture, and the reactive gas can permeate or degrade certain plastics, so glass with a screw-cap is used to contain the specimen safely and preserve it for analysis.
