A vacuum oven is a versatile piece of laboratory equipment commonly used for delicate heating and drying processes. They are commonly used when drying very small parts or when dealing with removing flammable solvents like methylated spirits or alcohol. The oven usually functions at a steady temperature of around 3600 °F to 4500 °F (2000 °C to 2500 °C). Read More…

What Is a Vacuum Oven?
A vacuum oven is a versatile piece of laboratory equipment commonly used for delicate heating and drying processes. They are commonly used when drying very small parts or when dealing with removing flammable solvents like methylated spirits or alcohol. The oven usually functions at a steady temperature of around 3600 °F to 4500 °F (2000 °C to 2500 °C).
How Vacuum Ovens Function
Vacuum ovens are commonly used to remove moisture, gasses, or other possible unstable chemicals from equipment or other items while preventing any reactions. They are usually used at the final step in producing medical devices, epoxies, semiconductors, oils, and other packaged food products.
Drying items in a vacuum significantly reduces oxidation and ensures the gentle drying of delicate products. They also reduce the chances of exposing employees to harmful chemicals.
The vacuum oven is aptly named because it heats items much like an oven and is useful when a vacuum-sealed chamber is required. The vacuum chamber is the primary mechanism for drying items.
With reduced pressure in the vacuum chamber, the boiling points of most substances are reduced, ensuring that they completely evaporate unwanted substances without burning or damaging equipment. This is a similar phenomenon to how the boiling point of water is greatly reduced at high altitudes.
Specifications of Vacuum Ovens
The crucial parameters to consider when specifying vacuum ovens are oven temperature range, oven capacity, and pressure range. Temperature range refers to the maximum temperature at which the unit operates and can maintain the rated specifications.
Capacity refers to the total capacity of the interior space of the unit. Vacuum ranges for the vacuum ovens can be roughly or as low as (< 760, > 1 torr), a medium of (< 1, >10-3 torr), a high vacuum of (< 10-3, >10-8 torr), and sometimes an ultra-high vacuum of (< 10-8 torr) and other elevated pressures of (> 760 torr).
Types of Vacuum Ovens
There are two main types of vacuum ovens: electronic-controlled ovens and microprocessor-controlled ovens.
Electronic Controlled Ovens
These types of ovens offer enclosed heating of elements to ensure stabilized and uniform heating. Overheating is reduced by the use of an electronic control backup. A panel in the front controls the primary temperature, purge gas, control valves, and vacuum gauges.
The gas and the vacuum system connectors at the back allow the user to replace the air with non-reactive gas. In addition, the user can look through the window to see the temperature within the chamber.
Microprocessor Controlled ovens
Microprocessor-controlled ovens provide an array of self-testing indicators, a thermostat, and controls to prevent damage to samples. It can be programmed to set on or off cycles, and the front panel alerts users to open thermocouples, changes in temperature, or any other occurrences.
Applications of Vacuum Ovens
Vacuum ovens are useful in removing excess moisture within a substance through the effects of high temperature and reduced pressure. This functionality is very common in cleaning medical equipment and separating moisture from oils.
The vacuum pump reduces the overall pressure in the chamber while the oven provides the required heat energy. Other common uses are curing or drying textiles, rubber, and ceramics. The use of vacuum ovens also simplifies botanical extractions.
Advantages of Vacuum Ovens
Vacuum ovens are favorable because they can reduce the substance's boiling point and hence are suitable for heat-sensitive substances. They are also suitable for samples that do not dry easily, such as very small granular samples.
The vacuum-drying method is suitable for cleaning complex mechanical parts. The inert condition deals with the explosion of oxides. Vacuum ovens also ensure that equipment handlers are not affected by the dangerous chemicals that need to be cleaned from equipment.
Choosing the Correct Vacuum Ovens Manufacturer
To make sure you have the most beneficial outcome when purchasing Vacuum Ovens from a Vacuum Ovens Manufacturer, it is important to compare at least 4 Suppliers using our list of Vacuum Ovens companies.
