1931W. J. Elford in Jrnl. Path. & Bacteriol. XXVIII. 507, I propose to refer to these new membranes as gradocol membranes, since they are products of a graded coagulation of collodion. 1953Rhodes & van Rooyen Textbk. Virol. (ed. 2) i. ii. 12 Suspensions of virus particles are filtered through a series of ‘gradocol’ membranes of varying degrees of porosity, and the filtrates tested for the presence of virus. 1964Wilson & Miles Princ. Bacteriol. & Immunity (ed. 5) i. xl. 1166 In estimating the size of virus particles ultrafiltration through Gradocol membranes is widely used. |
