The only special apparatus needed is a supply of metal annuli. The procedure estimates viability with 95 % fiducial limits of ± 9 %; it appears applicable to other aerobic bacteria, to yeasts and to spore suspensions., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-24-1-15
