It is a device used in the laboratory, to sterilize and dry glass or metal containers, removing all moisture from the containers. In addition, it transmits temperatures higher than those of the environment, allowing to remove all moisture.
It also offers dry heat sterilization at temperatures of 180 degrees Celsius for about 2 hours, leaving completely free of any biological activity.
It has appropriate characteristics, capable of establishing complex series of experiments with very sensitive loads, testing materials, subjecting electronic components to a drying process or regulating their temperature, hardening synthetic resins or heating plasticine, carrying out processes of temperature regulation, with levels of precision, uniformity and delicacy incomparable.
Functions of the ovens in a Laboratory
It is important that in the laboratories, have the ovens or ovens for sterilization, washing and drying of instruments that have been used, placing metal and glass containers inside the oven and thus offer optical conditions, for future use.
It should be noted that the use of this equipment generates dry heat at a temperature of 180 ° C for a couple of hours, allowing the sterilization of all the material disposed, in the drying cavity. It also eliminates any occurrence of contaminating biological activity in the vessels.
Likewise, the furnace extends its temperature progressively as time passes, as well as its programming. It has a control board that shows the regulating point and the actual temperature inside the oven, in which it can be displayed for control.
It has important features for its operation, which are
- Natural convection: Separates air from the environment, in which the oven is located.
- Forced convection: In this type of oven, air is generated inside the machine in a forced manner. This air is at room temperature.
Types of Furnaces
- Gravity convection furnaces: transfer heat to temperatures of +-2°C, and the time in which it stabilizes, is calculated between 45 minutes to 1 hour, this can vary by the volume of material within the equipment and the size. Working Temperature +5°C ambient temperature up to 250°C are used in studies where it does not require such a rigorous temperature accuracy, since they can exceed their internal temperature by thermal inertia, up to 12°C.
- Forced convection and Horizontal Flow furnaces: transfer heat between areas with different temperatures, with an accuracy of +-0.5°C and the time in which it stabilizes is calculated between 25 minutes to 40 minutes, this can vary by the volume of material within the equipment and the size. Working temperature +5°C room temperature up to 250°C.
- Air Jet Furnaces (Sterilizing Furnace): reaches an accuracy of +-1°C and the time in which it stabilizes is calculated between 15 minutes to 20 minutes this can vary by the volume of material within the equipment and the size. Working temperature +5°C room temperature up to 220°C.
- Vacuum furnaces: it has temperatures of +-1°C and the time in which it stabilizes is calculated between 20 minutes to 35 minutes, this can vary by the volume of material within the equipment and the size. Working Temperature 50°C to 200°C.
In summary, these ovens or oven, comply with dehydrate, sterilize, dry materials, cure and simulate environments, to complement the requirements of laboratories and optimize the use of materials to use.
