Rinse the bottles with running potable water until the soap is removed completely. the main green indicator will glow. Advertisement. Hot air oven is widely used in the medical industry to sterilize the equipment and other materials that are used in a laboratory. The steps for calibrating the oven temperature depend upon the type of oven controls you have on your model. Carried out in a hot air oven, the ideal temperature needs to be at least 160°C, with contents monitored at this heat for 45 to 60 minutes. To seal an opening, it is best to draw hot air from the oven and force it back into the opening. Introduction of Hot air oven. These units incorporate a secondary RTD mounted with the primary RTD (described previously) to provide a simple way to calibrate the controller and deliver accurate oven temperatures. Generally, they use a thermostat to control the temperature. If the oven temperature for your gas or electric range or wall oven does not match your expectations, you can calibrate (adjust) the oven temperature. At their most basic, laboratory ovens can also be used to sterilise lab equipment and glassware. Fortunately, there’s a standard user-friendly way for any oven temperature can be fixed. Alla France.
