Convection Ovens have surely made their way into the scientific community with their discovery. This is partially due to an extended range of variants they offer such as mechanical convection ovens, forced air convection ovens, gravity convection ovens, and so on. In this article, while we focus on discussing gravity convection ovens, you will simultaneously learn about other variants mainly in comparison. It is absolutely required for someone in the scientific field to be completely aware of every variant of basic equipment such as convection ovens in order to be updated with the technologies.
This will enrich your existing knowledge and also help you grow as a scientist in your field of interest. Therefore, if you are one of them, continue reading for you are to learn about interesting features of convection ovens—with special emphasis given on gravity convection ovens.
When you are looking for buying lab equipment, other than looking for specific features, you should always be mindful of the maintenance process because ultimately it all comes down to “how effortless is the maintenance?”. If it is heavy maintenance equipment, there is a lot more chance of it being damaged sooner than equipment having a low maintenance procedure.
For gravity convection ovens, you can be completely carefree about its maintenance. This is due to the fact that unlike most variants of convection ovens, they do not require any air-circulating system to be installed and maintained. A large part of maintenance goes to check the mechanics of air circulation from time-time which is also quite expensive if you need to keep changing them. Therefore, in this case, the gravity convection oven is your perfect pick.
Modified interior to ensure uniform heating:
It might occur to you that a gravity convection oven will have a defective air-circulation system, thereby a defective heating system because it is devoid of a fan. But in reality, it is possibly more effective in terms of heating. This is because only in this variant will you be finding a three-side heating facility to compensate for the absence of an air-circulating system. A three-side heating facility ensures uniform heating from three sides—right, bottom, and left wall—of the device. Moreover, they are equipped with an in-built sensor that makes sure the heating process is uniform throughout the number of heating cycles.
Suitable for drying or heating lightweight samples:
You should be aware of a device’s specialty to maximize its potential and usage. In the case of a gravity convection oven, the specialty is that it best opts for drying or heating of small objects with minimal weight. Ideally, it is used for drying/heating powder samples in various biochemical labs. It is solely made for lightweight samples because it lacks an in-built air circulation system which can disturb such delicate samples. Hence, if you are working with powder samples or similar lightweight samples, it is best that you choose a gravity convection oven.
No requirement for component installation:
For other variants such as mechanical convection ovens, forced exhaust ovens, side draught ovens, etc. there is always room for improvement for optimized performance. For example, a mechanical convection oven will require an additional more efficient air-circulating device for optimized performance. Similarly, in the case of forced exhaust ovens and side draught ovens, there is an additional requirement of vents and heating coils and preheating plastic sheets respectively. However, in the case of a gravity convection oven, you do not need to spend on additional components, nor does it have space for the installation of further components. It is a simple and efficient model of a convection oven with a ready-to-use facility.
Multiple tasks in one heating cycle:
You can perform a row of tasks in your gravity convection oven in one heating cycle unlike other variants with an in-built air-circulating fan. The presence of such a fan minimizes the possibility of multi-tasking with one heating cycle because it needs to have enough space in order to circulate and re-circulate the hot air inside. Such is not the case with our variant in focus. If you have a number of samples of a similar kind and need to dry or heat them, you can prefer to do it all at once for your convenience. This is because low-weight small samples will not require much space and the absence of an air-circulating device will help in the process of disturbance-free heating of all the samples. Additionally, due to the three-side heating facility, all your samples will be heated efficiently and uniformly.
