Description
Exchange block 20 x 1,5 ml / 15 x 0,5 ml is a dual-format interchangeable sample block for 20 reaction vessels of 1,5 ml and 15 reaction vessels of 0,5 ml. It fits Thermomixer TS and TSK 100 instruments, allowing simultaneous temperature control and mixing of mixed tube sizes in one run. This configuration is useful for sample preparation, incubation and shaking protocols that combine microcentrifuge tubes of different volumes. The block from manufacturer Zefa holds the vessels securely to maintain thermal contact and positional stability during operation. Laboratories can exchange this block quickly when workflows require both 1,5 ml and 0,5 ml tubes without changing the base thermomixer. Supplied as one piece, it supports flexible use of the TS/TSK 100 platform in research and routine laboratory settings. Ideal for thermos shakers and thermomixers where mixed-volume processing improves efficiency and instrument utilisation across sequential experiments.

Questions about Exchange Block 20 x 1.5 ml / 15 x 0.5 ml for 20 reaction vessels 1.5 ml and 15
What is this article?
Exchange Block 20 x 1.5 ml / 15 x 0.5 ml for 20 reaction vessels 1.5 ml and 15 is the article on this page. Luminix Health distributes Zefa for laboratory use. It sits in Stirring & mixing accessories, inside Stirring, shaking & mixing, in Instruments de laboratoire.
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.
