Vortexers are indispensable devices in the laboratory providing fast results through their very intuitive handling and their performance and thus convincing overall. They are used for different applications e.g. the dissolution of solids or of cell pellets in a medium or the mixing of samples in test tubes. Heidolph offers three different Vortexer models being able to process a wider range of samples more efficiently by means of additional accessories.

The reciprocating movement is a vigorous horizontal shaking movement and is therefore suitable for various extraction applications, such as Babcock analysis or the determination of pesticide residues in different media. Particularly where an increased number of samples have to be handled during a liquid-liquid extraction, use of suitable holding clamps for separatory funnels can facilitate the workflow.

The particularly gentle movement of a 3D platform wave shaker is used, among other things, for staining membranes after blotting processes. The sensitive membranes are gently flushed during the incubation times and the bands are stained successfully.

Overhead shakers are compact devices that are suitable especially for challenging applications. Large models such as our Reax 20 are equipped with a separate emergency switch ensuring safety even during heavy loads of up to 30 kg. This allows the user to mix color and varnish samples safely, to prepare soil samples or to dissolve poorly soluble salts. The smaller Reax 2 is often used in molecular biology or biochemistry to extract different products from cells or tissues.
