Description
Exchange block 35 x 1,5 ml is an interchangeable laboratory block configured to hold 35 reaction vessels of 1,5 ml. It is designed to fit Thermomixer TS and TSK 100 instruments, enabling simultaneous temperature control and mixing of multiple small-volume samples. The block accepts standard 1,5 ml reaction tubes commonly used in molecular biology, enzymatic assays and routine sample-preparation workflows. Secure seating of each vessel supports consistent heat transfer and stable performance during incubation and shaking cycles. This accessory from manufacturer Zefa is intended for laboratories that operate thermomixers and thermos shakers and need rapid format changes between different tube capacities. Supplied as a single piece, the exchange block integrates directly into the corresponding instrument platform. Its 35-position layout increases sample throughput on a single base unit while retaining the geometry required for reliable contact and agitation. Ideal for parallel processing of numerous 1,5 ml reactions under controlled thermal and mixing conditions in research and routine laboratory settings.

Questions about Exchange Block 35 x 1.5 ml for 35 reaction vessels 1.5 ml fits Thermomixer
What is this article?
Exchange Block 35 x 1.5 ml for 35 reaction vessels 1.5 ml fits Thermomixer 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.
