Buying a Vacuum Oven
A vacuum oven is a type of laboratory oven used for drying and heating chemicals, samples, and compounds. It is designed to expel volatile agents and reach extremely high temperatures. Vacuum ovens are also beneficial for curing of coatings and other processes which involve heat exposure. The oven creates a closed system and effectively removes oxygen within the chamber to retard oxidation and protect sensitive materials.
Before purchasing a vacuum oven, one should consider the following things:
1. What will the main purpose of the oven be?
There are several kinds of vacuum ovens, each equipped to perform different actions, and so it is important to understand the type of application you will require the oven for before you begin shopping around. Understanding your desired application will also help you narrow down the specifications you need for the oven.
2. Is the material inside the oven flammable or hazardous?
This is important when choosing the type of oven best suited for your materials. If the material is explosive or combustible, you will want to purchase an oven with a spark-proof interior, UL-approved safety switch, and a temperature shut-off valve.
3. What temperature range will the oven need to reach?
The temperature ranges for vacuum ovens vary drastically, from 212 to 450 degrees F. Depending on the kind of application, you will need to select an oven that is capable of reaching the desired temperatures.
4. What type of vacuum system is needed?
Vacuum ovens are commonly used in combination with a separate vacuum pumping system. The most common forms of pumps used with vacuum ovens are piston pumps and centrifugal pumps. The type of pump you need will depend on the application and the type of materials.
5. How quickly will the material need to be heated?
The number of materials that can be heated in a vacuum oven at once will depend on the size, type, and efficiency of the oven. Certain ovens are equipped with faster heating systems which can be advantageous if the material needs to be heated quickly.
6. Is maintenance required for the oven?
Some vacuum ovens require maintenance, such as cleaning the interior surfaces, calibrating the temperature, and replacing parts.
Once you have considered the answers to these questions and have determined your necessary specifications, you can begin searching for the perfect vacuum oven that meets your needs. Online platforms such as Amazon and eBay are great options for finding a vacuum oven, or you can search for your desired oven in online catalogs or contact a local dealer. When shopping for a vacuum oven, keep in mind that it is a significant investment, so it is beneficial to research the oven’s capabilities, read reviews, and look into the warranty and customer service provided by the manufacturer.
To ensure you get the best value for your purchase, it is also helpful to compare prices on different websites and do an internet search for any discounts or special offers that may be available. Vacuum ovens are an increasingly popular and essential tool for many types of applications, and with the right research and understanding, you can find the perfect oven to meet your specific needs.
