Due to the fact that purchasing such a machine is an investment, it might pay off to read some more info so that you’re able to correlate its features with your requirements. To make the right call, just keep reading.



The first thing you should be on the lookout for is whether or not the product you intend to spend your money on has acquired some sort of safety certification. Besides, you should look at the goal you’re trying to achieve, as well as the materials you may want to use with the vacuum oven so that you prevent any accidents from happening. During the vacuum drying process, there should not be any gasses, fumes, fog, or dust inside the chamber as these can lead to the occurrence of explosions. If you do plan to utilize one of the formerly mentioned substances, it might be a good idea to look for a model that’s explosion-proof.


Heating system

The chamber load has to be heated one way or the other, and based on the info that we have found on this matter, there are two different ways of making this process possible. One of them consists of a heat transfer from the walls on the sides of the chamber to the shelves whereas the other relies on the use of directly heated shelves. Whether the first heating system relies on the use of heated air jackets or not, the fact of the matter is that it is considerably more time-consuming compared to the second, in spite of the fact that the temperature achieved is homogenous. By contrast, plate heating systems need less time to do what they are supposed to. In other words, it really boils down to your workflow productivity and the amount of time you have available.

Size and number of shelves

Depending on the space you will install the unit in, it might be worth seeing whether the dimensions of the product are reasonable so that you’re able to install it wherever you may like. The chamber size also matters as this is the part that you will utilize with the samples. How about the size and number of shelves? Are there any pans provided along with the base unit or will you have to purchase them separately? While getting one of the best cheap vacuum ovens might look like a good idea in the beginning, extra costs might make the unit more expensive in the long run. If you’ve owned a model that has broken down, it might pay off to look for a vacuum oven with pump only if you don’t have it already.


Ease of use

Operating a vacuum oven isn’t extraordinarily simple, particularly if you have no prior experience with working with machines of this type. Even though reading the instructions provided by the manufacturing brand is the way to start learning about the unit you’ve bought, we’ve noticed that some models are more user-friendly compared to others. In fact, many of the modern options we’ve come across while sifting through the many available in today’s market have convenient features such as digital pressure controls or digital temperature controls. Others have predefined vacuum and temperature cycles.

Many models also come with various alarms that can notify users whether something wrong is happening inside the machine or whether they should shut it down for one reason or the other.
