Measurement of formaldehyde concentrations in a subatmospheric steam-formaldehyde autoclave.
A method has been developed for measuring formaldehyde concentrations in a subatmospheric steam-formaldehyde autoclave. Data obtained using this method indicate that the concentration of formaldehyde in the chamber atmosphere is not homogeneous and that it decreases rapidly with time. The penetration of formaldehyde vapour into narrow tubes has also been investigated and was shown to be depende...
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 کاملProcessing urinary endoscopes in a low-temperature steam and formaldehyde autoclave.
Methods of disinfection and sterilisation of urinary endoscopes are considered. A small mobile low-temperature steam and formaldehyde autoclave (Miniclave 80) is evaluated and shown to be satisfactory for this purpose as judged by a variety of relevant microbiological test pieces.
متن کاملResidual formaldehyde after low-temperature steam and formaldehyde sterilization.
The levels of formaldehyde remaining in various articles have been estimated immediately after a low-temperature steam and formaldehyde sterilizing process and after various periods of aeration. These levels have been compared with the levels of ethylene oxide remaining after exposure to an ethylene oxide sterilizing process. In rubber and polythene and a plastic, formaldehyde levels are low an...
متن کاملsteam-formaldehyde sterilizer for gas penetration efficiency
SYNOPSIS A test piece is described for monitoring the performance of low-temperature steam-withformaldehyde sterilizers. Comparative tests have shown it to be more difficult to penetrate than an arterial catheter when exposed to the same sterilizing conditions. It is permanent and simple to use and maintain. The growth or non-growth of bacterial spores, in the convenient form of spore strips, i...
