Lab Ovens and Lab Furnaces
Design with sample protection as the primary goal
Lab ovens are an indispensable utility for your daily workflow, from simple glassware drying to very complex temperature-controlled heating applications. Our portfolio of heating and drying ovens provides temperature stability and reproducibility for all your application needs. LABCOMPANION heating and drying ovens are designed with sample protection as a primary goal, contributing to superior efficiency, safety and ease of use.
Understand natural and mechanical convection
Principle of natural convection:
In a natural convection oven, hot air flows from bottom to bottom, so that the temperature is evenly distributed (see figure above). No fan actively blows the air inside the box. The advantage of this technology is ultra-low air turbulence, which allows for mild drying and heating.
Principle of mechanical convection:
In a mechanical convection (forced air drive) oven, an integrated fan actively drives the air inside the oven to achieve uniform temperature distribution throughout the chamber (see figure above). A major advantage is excellent temperature uniformity, which enables reproducible results in applications such as material testing, as well as for drying solutions with very demanding temperature requirements. Another advantage is that the drying rate is much faster than natural convection. After opening the door, the temperature in the mechanical convection oven will be restored to the set temperature level more quickly.
