Profile: Osworld Scientific Equipments Pvt. Ltd. is a manufacturer, supplier and exporter of laboratory equipments. We are an ISO 9001:2008 certified company. Autoclave is a device to sterilize equipment and supplies by subjecting them to high pressure saturated steam at 121 °C or more, typically for 15-20 minutes. Autoclaves are usually made of steel and have various configurations for removing air prior to pressurization. Downward displacement autoclaves use gravity to remove air. Steam pulsing autoclaves use pulses of steam along with pressurizing and depressurizing to reach optimum pressure. Vacuum pump autoclaves suck air out for pressurization. Superatmospheric autoclaves are a combination of steam pulsing and vacuum pump techniques.
