This case contains an ampoule of the First International Standard (1945) of penicillin, five ampoules of early crystalline penicillin and one sample of an undefined potency. Penicillin samples of undefined potency were collected from government agencies and industrial manufacturers in Britain and the USA by the Department of Biological Standards (DBS) at the National Institute for Medical Research, Hampstead, in 1944, in order to determine an International Standard.
