Natural Convection Ovens TO

For research, development, testing and quality control – you need an efficient and consistent laboratory oven.

These models feature natural heat convection, with no fan air circulation, providing gentle heat within the oven chamber.

Australian Made by Thermoline, our ovens are reliable and long-lasting – perfect for all laboratory and industrial functions.


The natural convection laboratory ovens, manufactured by Thermoline, operates through the natural convection process, which relies on the movement of air caused by the difference in density between the heated and unheated air. 

The chamber is made of 316 stainless steel and is insulated with 50mm fibreglass to minimise heat loss. Shelving is stainless steel and adjustable. 

The natural convection process may result in slower heating rates and longer drying times compared to forced convection ovens and the spatial temperature uniformity is not like what is seen in a fan forced oven. One advantage of a natural convection oven is that it does not require a fan to circulate the air, which makes it quieter and less expensive to operate than forced convection ovens.

What is the difference between a lab oven and a drying oven?
A drying oven is design to remove moisture from the oven chamber by introducing dry air into the chamber. These ovens are typically designed to provide a consistent and low humidity environment, which is important for drying materials effectively. Drying ovens often feature a vent or exhaust system that allows moisture to be removed from the oven workspace. Generally speaking, a regular lab oven does not exhaust air so the moist air may continue to circulate inside the chamber.  
Can I use a lab oven as a glassware drying oven?
You can, however, as the moist air from the wet samples would be recirculated within the chamber, the drying rate is reduced and in many cases, will not properly dry.
What is the process difference between a lab oven and a drying oven?
A drying oven is designed to remove moisture from the oven chamber by introducing dry air. A lab oven's sole purpose is to designed to heat samples only. It works by recirculating the air around the chamber over a heating element that is controlled by a temperature controller. 
How do Laboratory Ovens Work?
A laboratory oven works via the principle of convection. The heating element is not located within the specimen chamber of the oven, but in a separate section of the oven.
What is the difference between Oven and Incubator?

A laboratory oven and a laboratory incubator are both commonly used in laboratory settings, but they have different purposes and functions.

A laboratory oven is used for drying, heating, or sterilising materials and is typically designed to operate at higher temperatures than a laboratory incubator. A laboratory oven typically uses air convection to circulate hot air throughout the chamber, and can be set to a specific temperature or temperature range. Ovens generally control temperatures +80°C and up.

A laboratory incubator, on the other hand, is used for maintaining a controlled, temperature-regulated environment for cell cultures, microbiological specimens, or other biological materials. Unlike a laboratory oven, a laboratory incubator is designed to maintain a temperature close to the physiological temperature of the material being incubated, usually between 30°C and 40°C. A laboratory incubator can also provide additional functions, such as humidity control and CO2 control, which are essential for the growth and maintenance of many types of cells and biological specimens.
