Disinfection by steam

Disinfection of Cystoscopes by Subatmospheric Steam and Steam and Formaldehyde at 80 ° C

The various methods of disinfection at present used for endoscopic instruments include immersion in an antiseptic solution (Miller et al., 1960), pasteurization in water (Francis, 1959), exposure to formalin vapour in a cabinet, and exposure to ethylene oxide. Though certain endoscopes are able to withstand autoclaving, this method cannot be used for all parts of the endoscope or for children's...

Disinfection of woollen blankets in steam at subatmospheric pressure.

Blankets may be disinfected in steam at subatmospheric pressures by temperatures below boiling point inside a suitably adapted autoclave chamber. The chamber and its contents are thoroughly evacuated of air so as to allow rapid heat penetration, and steam is admitted to a pressure of 10 in. Hg below atmospheric pressure, which corresponds to a temperature of 89 degrees C. Woollen blankets treat...

Disinfection of heat-sensitive material by low-temperature steam and formaldehyde.

Steam under subatmospheric pressure at temperatures below 90 degrees C. rapidly killed nonsporing organisms after air had been removed by a high-vacuum pump. Most bacterial spores were killed but small proportions of the populations were very resistant. The destruction of spores was not logarithmic. The addition of formaldehyde vapour to the steam greatly increased its sterilizing power, with d...
