Laboratory ovens are multi-purpose equipment used in scientific and manufacturing industries. They are used in a wide variety of applications. Their roles are important in the process of baking, curing, or drying various substances which are later used in science labs, the pharmaceutical industry, and the manufacturing process. A strong laboratory oven will last for several years of heavy use day after day and work great for years, so it’s worth thinking about choosing the right oven for your needs.
Laboratory ovens are common equipment used in most labs, used for high-forced volume thermal convection applications. They provide even heating throughout the entire unit, regardless of the temperature at which it is set. Most lab ovens are built to provide temperature ranges of ambient to about 300°C. Ovens with higher operating temperatures are normally used for specialized applications in physics, material processing, and electronics. Other uses include annealing, die-bond curing, drying, polyimide baking, and sterilizing.
The ovens have double walls with a layer of insulation between them, to save energy by preventing it from escaping. The inner wall is constructed of low thermal conductivity materials. The outer layer is made of metal. They are fitted with a hot air circulation fan, which allows a uniform distribution of heat.
The Uses of Lab Ovens
Laboratory ovens heat the material using the convection process. The content is put in a different chamber instead of the primary chamber. It stops the material from being altered but the heat is strong enough to dry it or cure it. When considering a laboratory oven, take into account the types of applications you will be performing.
- Annealing: The process of annealing involves heating and then cooling material, such as glass or steel, 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. These annealed materials can be cut and shaped more readily to be used in the production of things such as syringes and catheters.
- Die-bond curing: combines drying and baking within the oven to cure substances to harden their chemical composition. Examples include creating epoxies, glues, plastics, and rubbers used in polymer research, nanotechnology, and semiconductor industries. The increased bond strength is also extremely useful when connecting components directly to the circuit used in military, space, and medical systems.
- Drying: Removing moisture from samples. Typically performed in environmental, biological, and clinical laboratories and a prerequisite for them.
- Forced air and vacuum ovens are best suited to samples that are easily broken down, as these remove moisture and lower the boiling point of water, letting the sample be dried at a lower temperature.
- Gravity convection ovens, meanwhile, are often used to dry fine particles as these are liable to scatter with high airflow and need a more natural airflow to protect these delicate samples.
- Polyimide baking: Added to the oven in liquid form, the polyimide is then thermally baked to create a thin film or a layer for various uses, including stress buffer coating for redistribution layers, adhesion, chip bonding.
5.Sterilising: used to sterilize lab equipment and glassware. Heats materials to a temperature of at least 160°C, with contents, monitored at this heat for 45 to 60 minutes. At this temperature, biological contaminants such as mold and bacteria are destroyed, resulting in sterile laboratory instruments, glassware, or equipment.
