Cooling times for various autoclave loads were recorded using thermocouples. Loads which may be encountered during normal laboratory working require between 17 and 174 minutes to cool to 100 degrees, C and up to 260 minutes to cool to 95 degrees C. Such long cooling times had an adverse effect on nutritive properties of bacteriological culture medium. Observations are made on some factors which...

Autoclave curing is one of the most energy consuming processes in manufacturing carbon fibre reinforced polymers. In order to improve efficiency, needs understand usage an autoclave and factors that influence it. This work presents two thermodynamic based models for estimating consumption autoclave. The first model analytical approach on simplified heat capacity equation. second combines Multi-...

Polyethylene (PE) is one of the most widely used polymers in chemical industry. In all the PE processes, high-pressure autoclave process is generally considered as the most profitable segment of the polyethylene business worldwide in recent years. Depending on different grades of the product, reactor zone temperatures in this autoclave process can be in the range 150-230°C and pressure in the r...

A steam autoclave was used to sterilize bacteria in clinical solid waste in order to determine an alternative to incineration technology in clinical solid waste management. The influence of contact time (0, 5, 15, 30 and 60 min) and temperature (111 °C, 121 °C and 131 °C) at automated saturated steam pressure was investigated. Results showed that with increasing contact time and temperature, th...

Formulations of tomato puree with grape skin fibres (Chardonnay variety) having varying particle sizes were studied. The contents of flavonoids (by HPLC-DAD) and proanthocyanidins (n-butanol/HCl assay), reducing capacity (ferric ion reducing antioxidant power, FRAP) and anti-glycation activity by a bovine serum albumin (BSA)/fructose model system were analysed in vitro. A liking test was perfor...

Six strains of Gram-negative non-motile bacilli from cats have been described. They do not grow on ordinary media. They do grow, however, on a medium to which an autoclave-labile substance alone has been added as an accessory growth factor. These bacilli are similar to Bacillus parainfluenzaaeisolated from man. One strain of a Gram-negative non-motile bacillus more exacting than Bacillus influe...
