Laboratory Oven
A laboratory oven, also known as a drying oven, is a device designed to remove moisture from various materials, allowing samples to dry in the shortest possible time. These ovens generate heat and, in some models, use a fan to introduce fresh, dry air into the chamber while simultaneously expelling moist air through a vent. This process facilitates rapid drying of samples.
Laboratory ovens are essential equipment in laboratories, serving purposes from simple drying of glassware and laboratory samples to more complex applications requiring precise temperature control. Therefore, laboratory ovens must provide high temperature accuracy and ensure repeatability to achieve consistent and reliable results under identical conditions.
Types of Laboratory Ovens Based on Air Circulation
Laboratory ovens are categorized into Gravity Convection Ovens and Mechanical Convection Ovens (with or without fans).
Gravity Convection Ovens
In gravity convection ovens, heat distribution is based on the natural movement of warm air rising. There is no circulatory fan to actively distribute air within the chamber. The advantage of this technology lies in its minimal airflow, making it suitable for gentle drying applications.
Mechanical Convection Ovens
A mechanical convection oven, or fan-equipped oven, continuously circulates air within the chamber using a fan. This results in even temperature distribution throughout the chamber. The benefits of this process include better temperature uniformity and enhanced repeatability of results.
Additionally, compared to gravity convection ovens, fan-assisted ovens dry samples more quickly. After opening and closing the oven door, the temperature in a fan-equipped oven returns to the set level much faster.
Applications of Laboratory Drying Ovens
Laboratory drying ovens are used across various fields, including chemistry, physics, biology, engineering, industrial processes, food production, pharmaceuticals, and more. Common applications include:
- Drying Laboratory Samples: Laboratory ovens are used to dry items such as solid filters, test tubes, powders, and more.
- Sample Strength Testing: In certain laboratories, ovens test the strength of samples. For example, samples made of concrete, cement, asphalt, and other materials are placed in the oven at a specific temperature to evaluate their strength.
- Testing Physical and Chemical Properties: Laboratory ovens are also used to test the physical and chemical properties of samples. For instance, they are employed to analyze characteristics such as solvent extraction, absorption, leakage, tensile strength, hardness, and more.

3. Precision and Accuracy
According to DIN 12880 standards, the precision of an oven includes the following parameters:
- Fluctuation:
The temperature variation at a single point within the chamber over a specific time. - Variation:
The temperature difference across multiple points in the chamber. It is calculated by finding the difference between the highest and lowest average temperatures across 27 measured points. - Deviation:
The difference between the oven’s display temperature and the actual temperature at the center of the chamber.
4. Heating-Up Time
This refers to the time required for the oven to reach the set temperature (e.g., 150°C) from ambient temperature, staying within an allowable deviation (e.g., ±1.5°C).
5. Recovery Time
Recovery time is the duration needed for the oven to return to the set temperature after the door is opened for 30 seconds.
6. Air Exchange Rate
For drying purposes, the rate at which air is exchanged in the chamber is crucial. This parameter, often expressed in air changes per hour, indicates how effectively the oven replaces air, directly impacting the drying efficiency of samples.

Safety Features: Secondary Controller or Safety Thermostat
To mitigate risks from controller malfunctions, the DIN 12880 standard requires laboratory ovens to include a secondary controller. This acts as a safety mechanism, shutting off power to the heating element in case of overheating. Depending on the design, these safety controllers are categorized as follows:
- Class 1:
The safety controller is preset by the manufacturer to the maximum temperature and disconnects power in case of overheating. This protects the device but may disrupt experiments. - Class 2:
The user can adjust the safety controller slightly above the setpoint. If the temperature exceeds this limit, power to the heating element is cut off, protecting both the sample and the device. - Class 3:
The most advanced class, where the safety controller maintains the temperature within a user-defined range, allowing experiments to continue. This class has three subcategories:- Class 3-1: Activates when the temperature exceeds the set range.
- Class 3-2: Activates when the temperature falls below the set range.
- Class 3-3: Activates when the temperature deviates above or below the set range.
