Machine for automatic bacteriological pour plate preparation.
A fully automatic system for preparing poured plates for bacteriological analyses has been constructed and tested. The machine can make decimal dilutions of bacterial suspensions, dispense measured amounts into petri dishes, add molten agar, mix the dish contents, and label the dishes with sample and dilution numbers at the rate of 2,000 dishes per 8-hr day. In addition, the machine can be prog...
متن کاملEffective Use of Synthetic Seed Technology in the Regeneration of Dendrobium White Fairy Orchid
The synthetic seed technology is becoming popular due to its wide application in germplasm conservation and for exchanges between countries in the floriculture trade. In this study, this method was used to study the germination and conversion capabilities of orchid species Dendrobium White Fairy when stored at different storage times and with different storage containers. A high germination per...

متن کاملImproved plating efficiencies for human tumors cloned in capillary tubes versus Petri dishes.
As now constituted, the human tumor cloning assay performed in Petri dishes has several limitations including: (a) not all patients' tumors form colonies in the assay; (b) the plating efficiencies (number of colonies formed/number of cells plated) are low; and (c) a large number of tumor cells are required to perform drug sensitivity testing. In this study the use of capillary tubes, as vessels...
متن کاملDecontamination of laboratory microbiological waste by steam sterilization.
A steam sterilizer (autoclave) was tested to determine the operating parameters that affected sterilization of microbiological waste. Tests involved standardized loads (5, 10 ad 15 lb [ca. 2.27, 4.54, and 6.80 kg, respectively]) contaminated petri plates in autoclave bags placed in polypropylene or stainless steel containers. Thermal and biological data were obtained by using a digital potentio...
