What are the Main Uses of a Ventilated Laboratory Oven?
Laboratory drying ovens can be used for the following functions, depending on the process required for the application.
The process of annealing involves the heating and then slow cooling of materials such as glass or steel, in order to reduce internal stresses and increase ductility. A high temperature oven is used in this process, often in the application of metallurgy, medical device manufacturing and material science industries. The annealed materials can be cut and shaped more readily to be used in the production of items such as syringes and catheters.
Curing involves the hardening of a chemical composition of a substance through the combination of drying and baking. This process is often used for the manufacturing of epoxies, glues, plastics and rubber in polymer research, nanotechnology and semiconductor industries.
Drying is the removal of moisture from a sample, which is necessary for many environmental, biological and clinical labs. Forced air and vacuum ovens are used to dry samples that are easily broken down, as these remove moisture and lower the boiling point of water which lets the sample dry at a lower temperature.Gravity convection ovens are often used to dry fine particles as these are liable to scatter with high air flow and need a more natural airflow to protect them
Sterilising involves the removal of bacteria or microorganisms and is commonly used to sterilise laboratory equipment. Laboratory ovens can be used to sterilise lab equipment and glassware. The ideal temperature needs to be at least 160°C, with contents monitored at this heat for 45 to 60 minutes.A slow cooling period is then required, as removing items from the oven straight away can cause them to crack, while the gradual cooling prevents potentially harmful air from entering the oven. The items then need to be dried using a temperature of 60°C.
How does a High Temperature Oven Work?
In a high temperature oven, which is also called a mechanical convection oven, an integrated fan actively moves the air inside the chamber, which results in an even temperature distribution throughout the chamber and provides rapid heat up and recovery time.The benefits of this type of oven includes the fact that it leads to reproducible results and that there is a much faster drying process when opening the door, which means that the temperature will recover to the set temperature faster. Vacuum ovens, which are also known as drying ovens, are used to remove moisture from objects without cooking them. The heat is produced from the side walls and requires an external vacuum pump to provide a low-pressure environment which minimizes oxidation during drying.In gravity convection ovens, hot air naturally rises when it expands and become less dense than the air around it. These ovens provide a low-cost alternative to forced convection ovens.
What is the Difference between an Incubator and a Laboratory Drying Oven?
The difference between an incubator and a laboratory drying oven may at first not be obvious. The two instruments both produce heat and are typically set within a boxlike casing.
However, the difference is that an oven produces temperatures typically ranging from 93.3 to 316 degrees Celsius, while an incubator typically ranges from 15.6 to 48.9 degrees Celsius.
