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...
متن کاملDisinfection 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...
متن کاملDisinfection 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...
متن کاملLow-Pressure Radiofrequency Cold Plasma for Disinfection of Gutta-Percha Cones
Background and Aim: Different methods have been proposed for rapid disinfection of gutta-percha (GP) cones. This study aimed to assess the efficacy of low-pressure radiofrequency cold plasma (LRFCP) in disinfection of GP cones compared to three chemical disinfectants. Materials and Methods: Seventy GP cones were allocated to seven groups of 10 each. All samples were initially sterilized with e...
متن کاملSteam-Water Capillary Pressure
Steam-water capillary pressure is of central importance in geothermal reservoir engineering, however it is still poorly known due to the difficulty making direct measurements. To this end, we have conducted experimental and theoretical studies over the past five years and have made significant progress in understanding fundamental steamwater flow. In this paper, we summarize and discuss the res...
