Description
Exchange block 24 x Ø 12 mm is an interchangeable sample block designed for 24 vessels with a maximum diameter of 12 mm. It is compatible with Thermomixer TS and TSK 100 instruments, enabling controlled heating and mixing of tubes or vials within this diameter range. The block provides stable positioning and thermal contact for incubation, sample preparation and shaking applications in the laboratory. From manufacturer Zefa, this exchange block allows users to adapt the thermomixer quickly when working with Ø 12 mm vessels instead of standard microcentrifuge tube formats. Supplied as a single piece, it integrates directly into the TS/TSK 100 platform and supports flexible instrument use across research and routine workflows. Laboratories benefit from rapid block exchange when different vessel geometries are required in successive experiments. Suitable for thermos shakers and thermomixers where reliable holding of 12 mm diameter vessels is essential for consistent temperature and mixing performance.

Questions about Exchange Block 24 x Ø 12 mm for 24 vessels with a maximum diameter of 12 mm
What is this article?
Exchange Block 24 x Ø 12 mm for 24 vessels with a maximum diameter of 12 mm is the article on this page. Luminix Health distributes Zefa for laboratory use. It sits in Stirring & mixing accessories, inside Stirring, shaking & mixing, in Lab instruments.
Stirring accessories are the bosses, the retort clamps and the spare knobs that hold an overhead stirrer over the vessel. The stand has to carry the motor's mass, not only the flask's.
Stirring keeps a mixture uniform or helps a solid dissolve. A magnetic stirrer spins a bar inside a closed vessel. An overhead stirrer drives a shaft when the liquid is viscous or the volume is large. A vortex mixer agitates a tube. A shaker moves a whole rack or a plate. The shape of the impeller and the speed decide whether the liquid turns over or merely spins. The vessels being stirred are indexed under ISO laboratory glassware.
