What is a lab oven called?
Vacuum Ovens – Also called drying ovens are used to remove moisture from objects without cooking them. Heat is produced from the side walls and requires an external vacuum pump to provide a low-pressure environment which minimizes oxidation during drying.
What is the function of hot air oven in laboratory?
Hot air ovens are electrical devices which use dry heat to sterilize. They were originally developed by Pasteur. Generally, they use a thermostat to control the temperature. Their double walled insulation keeps the heat in and conserves energy, the inner layer being a poor conductor and outer layer being metallic.
How do you use a laboratory oven?
Die-bond curing Through a combination of drying and baking, lab ovens cure substances in order to harden their chemical composition. This is a means of creating epoxies, glues, plastics and rubbers used in polymer research, nanotechnology and semiconductor industries.
What is a desiccator used for?
Desiccators are sealable enclosures containing desiccants used for preserving moisture-sensitive items such as cobalt chloride paper for another use. A common use for desiccators is to protect chemicals which are hygroscopic or which react with water from humidity.
What is the principle of operation of hot air oven?
The working of a hot air oven is based on the principle of dry heat sterilization. It makes the use of hot air to kill the microorganisms or to sterilize various equipment. The heat generated within the chamber travels in such a manner that it first sterilizes the surface of the equipment and then the centre of them.
What are the types of desiccator?
The four basic types of desiccators are standard, automatic, gas purge and vacuum.
What is the principle of autoclave?
An autoclave is a device that works on the principle of moist heat sterilisation, wherein saturated steam is generated under pressure in order to kill microorganisms such as bacteria, viruses, and even heat-resistant endospores from various types of instruments.
What can a laboratory oven be used for?
Laboratory Ovens Laboratory ovens are standard equipment found in most clinical, forensic, electronics, material processing, and, research laboratories. Laboratory ovens provide uniform temperature and precise temperature control for heating, baking, evaporating, sterilizing and other industrial laboratory functions.
How does a hot air oven work in a laboratory?
Hot air oven works in a manner so that items placed inside the oven don’t catch fire or meltdown. It basically works on the principle of conduction where heat travels on the surface of the material and then to the centre of the item. It is called dry sterilisation process because the treatment is done by using the hot air.
How are ovens used in the scientific world?
The Uses of Lab Ovens. The process of annealing involves heating and then cooling material, such as glass or steel, in order to reduce hardness and increase ductility. High-temperature ovens are used in this process, often in the application of metallurgy, medical device manufacturing and material science industries.
What is the purpose of a digital oven?
Standard digital ovens are mainly used for drying and heating processes while providing temperature control and safety. Heavy duty ovens are used more in the industrial laboratories and provide testing and drying for biological samples.

What do you need to know about the oven?
All personnel who operate ovens in the laboratory areas must be familiar in their operation. This includes on the job training on oven set-up, limitations, and precautions for preventing fires, over pressurization, and hazardous fumes. Always have a pair of hot gloves available near the oven for protection from hot surfaces.
