Hot Air Oven- The Definitive Guide

Hot Air Oven- The Definitive Guide

Hot air ovens are laboratory and scientific equipment which uses dry heat (hot air mixture) for sterilization of laboratory equipment.

The dry heat sterilization process is developed by Louis Pasteur to sterilize the equipment using the hot air ovens. Dry heat sterilization is the heating process in which the material which is placed inside the oven has the characteristics which will not melt, catch fire or changes its form while heating at high temperature.

Our hot air oven runs at extremely high temperature for several hours to destroy the bacteria. The general temperature range required for operation varies from 5°C to 450°C as per the customer need.

Most of the pharmaceutical industries use these hot air ovens to sterilize laboratory instruments and materials because they are simple to operate. The lab ovens also offered a quick dying process.  Further more details are provided so read more to get a complete understanding.

Laboratory oven construction

  1. Cabinet – Our hot air ovens are uses for triple-walled construction. The cabinets are made using stainless steel material. A single door is provided which is fitted on the heavy hinges and provided the required gasket to reduce the leakage.
  2. Insulation – The gap between the inner chamber and outer cabinet is filled with 3″ thick glass wool insulation. It provides insulation to the oven so that the heat is lost during operation.
  3. Tubular air heaters – The heaters are used to generate the heat inside the inner chamber. The heaters are placed on both sides of the inner chamber.
  4. Blower –The blower is used to recirculate the hot air mixture inside the chamber to achieve a uniform temperature profile inside the chamber. In a natural convection oven, the blower is not required. The desire temperature profile is achieved naturally.
  5. Temperature sensor – The temperature sensor senses the temperature the displays it on the screen.
  6. Trays and slots – The specially designed stainless steel rod trays are provided to place the material for heating. The number of trays and slots required can be changed as per the customer requirement.
  7. PID temperature controller – The microprocessor-based autotune PID controller is used to maintaining the desired temperature ranges during the operation.
  8. Main switch – It helps the turn on and turn off the hot air oven.
  9. Safety thermostat – It helps to protect your oven from temperature overshoot.
