16 horses versus a vacuum
Otto von Guericke, also known as the “Meister der Leere” (“Master of the Vacuum”), enters the marketplace in Magdeburg in the 17th century. Known for his theatrical demonstrations, the natural scientist has two teams of eight draft horses harnessed up and pits them against each other in an experiment. The spectacle begins with the horses attempting to pull apart two metal hemispheres that have been fixed together and had the air removed from between them. The audience watches the trial of strength with bated breath, expecting the hemispheres to give way under the sheer force exerted by the horses. But the air pressure differential between the outside and inside is huge: Without air between them, the metal parts are pressed together so strongly by the outer air pressure that it is impossible to separate them. The experiment, known as the Magdeburg hemispheres, is a success. Otto von Guericke’s findings continue to spark interest in engineers for generations to come and vacuums are used in numerous technical processes. Today, there is a whole host of applications in which the method can be found: Science, automation, the chemical and pharmaceutical industries, mechanical engineering, medical technology, and space technology all take advantage of the power that vacuums bring and the possibilities they hold.
BINDER is no exception, and uses vacuum technology to achieve certain aims in specific applications. Its range includes two different types of vacuum drying chambers developed specifically for safe, gentle drying of extremely sensitive substances or highly flammable materials. While the VD series is suitable for challenging drying processes, the VDL series provides an explosion-proof safety concept that complies with the European ATEX standard.
Vacuum drying chambers have a modular structure and can be combined to form a complete system consisting of a module and vacuum pump. The pump draws material out of the sealed interior, and the drop in the chamber pressure generates a state that is approximately a vacuum. In turn, this reduces the boiling point of the materials, allowing drying processes to be performed gently and safely. The vacuum drying chambers have different safety concepts.
