Drying ovens heating cabinets for the laboratory

What is a drying cabinet?

Drying ovens are often used in areas where low humidity is required. By dehumidifying equipment, work clothes, chemicals, biological agents or other materials, the drying cabinet provides the necessary protection and ideal storage in dry conditions. Most drying cabinets allow a temperature uniformity range that lies between room temperature and an upper limit of 250 °C.

Basically, the functioning of a drying cabinet can be compared to that of an electric oven. This is known as heat drying. However, as this causes a loss of performance with some items, other processes such as vacuum drying or damp vacuum can be used, depending on the area of work.

Drying cabinet, heating oven, tempering oven: What are the differences?

In principle, the term dry heat ovens stands for the categories drying cabinet, heating cabinet or temperature control cabinet. The main function of these appliances is to dry and/or heat their respective contents like a mechanical or gravity convection oven. For example, a warming cabinet is suitable for sample preparation and for heating fango or APS packs in physiotherapy.

The heating cabinet for laboratory and industry is often used for drying working materials. It is also used, for example, for ashing in water treatment plants or for carrying out high-temperature quality tests.

A temperature chamber or climatic chamber, on the other hand, is ideal for tasks such as testing the behaviour of materials under constant temperature and humidity conditions and for long-term tests.

Drying oven: Areas of application

The areas of application for drying cabinets are extremely diverse and range from research and science to quality assurance and equipping rescue centres. The ovens are designed for following areas:

• Medicine: A warming cabinet and compact heating is used in medicine for the optimal storage of medical products, samples or medicines. In addition, the cabinets are used, for example, to heat sterile blankets and cloths or to sterilise medical materials.

• Research & science: Drying cabinets or lab ovens can be used in many ways in the laboratory. In addition to drying and sterilisation tasks, they are used, for example, for etching, baking, long-term heat storage or for temperature stress tests or accelerated ageing tests.

• Food industry, environmental technology or agricultural industry: These sectors use drying cabinets, for example, to determine the dryness or moisture content of certain products with the aid of rapid tests.

• Fire & rescue centres: In these fields of work, drying and drying cabinets are increasingly used for drying work clothing. In addition, rescue materials such as blankets or cloths can be stored and heated in a sterile environment.

Different methods of drying

In the MedSolut.com assortment you will find a wide range of different drying and incubation cabinets. Depending on your profession and the materials you work with, it is important to choose the right drying method. Here we can differentiate between the three most common processes.

Heat drying

Heat drying is the basic technique of a drying oven. It is also compared with the technology of an oven. In this process, the product to be dried can be heated in an ambient temperature range from 20 to 250 °C. The moisture is extracted in the process. Since materials such as electronic components are exposed to so-called thermal stress and can lose their conductivity through pure heat drying, other gentle drying processes and uniform heating have been developed over the course of time.

Vacuum drying

Vacuum drying is mainly used for food, chemicals and other sensitive materials. In this process, you expose the desired material to a vacuum. This has the effect of lowering the boiling point. This allows the moisture or water contained in the material to evaporate at a low temperature.

Humidity vacuum

Drying with the help of moisture vacuum is particularly suitable for metallic components and electronics. In this process, the vapour pressure difference at a humidity of 5 percent reaches a stage where the water molecules of the stored material exceed the adhesion strength. This allows the molecules to escape into the ambient air and the drying process to take place.

If you continue this process and reduce the humidity in the interior to 1 to 2 percent, a moisture vacuum is created. In the course of the process, the moisture absorbed by the material is then released back into the ambient air. This process prevents the development of thermal stress for the stored goods, as the risk of oxidation as well as the risk of internal metallic growth are stopped.

Types of drying or freezing cabinet

MedSolut.com offers an extensive portfolio of high quality drying cabinets. From biology to pharmacy, food industry to medicine or glassware drying, our heating and drying equipment is used in a wide range of applications. To choose the right cabinet, you should consider the type of drying process as well as the type of cabinet. Get an overview of the different types of heat or drying cabinets in our range:

Safety drying cabinets

In our range you will find a number of safety drying cabinets from various brand manufacturers. The cabinets can be flexibly integrated into the work area and provide you with optimum test results, e.g. for paints or coating materials containing solvents. Your materials remain optimally protected from external influences or manipulation.

For this reason, this type of drying cabinet is ideally suited for the laboratory. This versatile helper is also suitable for use as a laboratory heating cabinet, thanks to its high temperature accuracy. This is due to its high temperature accuracy, which can even withstand high air exchange rates.

Vacuum drying ovens

Vacuum drying cabinets from manufacturers such as Binder or witeg guarantee gentle and effective drying of samples and materials. Due to their proven technical features and innovative design, these modern devices are particularly suitable for high demands.

For this reason, they are often used in industrial and scientific laboratories. Depending on the design, you can dry your samples and materials of both flammable and non-flammable solvents. A unique safety concept, individually adjustable pressure control and precise temperature control guarantee that the contents are not only dried quickly, but very gently.

Test cabinets

A sample or product is exposed to different conditions during the manufacturing process, storage, transport or application. These include, for example, thermal or climatic influences that can have an effect on the product's service life, among other things. Test cabinets ensure that you can test the sample or product in the best possible way under specific conditions. They can be categorised, for example, as climate test cabinets, temperature shock test cabinets or environmental test cabinets.

Alternating climate cabinets

In our range you will find a selection of interchangeable air-conditioning cabinets from our brand manufacturers Binder and Rumed. The cabinets work with a temperature range of -20 °C to +180 °C, which makes them suitable for a variety of cold and heat tests. For cyclical temperature tests, they are an excellent alternative to costly individual solutions.

The interchangeable climatic chambers are easy to program and enable you to record data reliably. The cabinets are particularly suitable for stress and stability tests to test the effect of different climatic or temperature conditions on certain products or substances.

Desiccator

A desiccator is used to store and dry moisture-sensitive substances and products such as reference materials, reference samples, metallographic reed plates or DNA samples. A tightly sealed door protects the contents of the vacuum-tight glass cabinet from contamination by the ambient air.

Most desiccators guarantee a temperature resistance between -20 °C and +70 °C and can be flexibly adapted to your needs thanks to their adjustable inner shelves. In our assortment we have a versatile selection of devices from SICCO ready for you.
