Description
Interchangeable block for test tubes is a modular sample block designed to hold 8 test tubes in bores of Ø 13,5 mm, intended for laboratory thermoshaker applications. Each bore provides a defined seat for standard tubes of matching diameter, enabling parallel temperature control and mixing under reproducible geometry. The block is suitable for thermoshakers and for RS-TS series cooling/heating thermoshakers, allowing users to switch vessel formats quickly when protocols move between different tube sizes. By exchanging the block rather than the instrument, laboratories maintain continuous use of the same shaker platform while adapting to routine incubation, extraction or sample-conditioning steps. This interchangeable block from manufacturer Phönix Instrument is supplied as one unit and weighs 0,280 kg, so it can be stored and fitted with minimal handling effort. In analytical, clinical-support and general life-science laboratories, Ø 13,5 mm tube blocks are commonly selected for mid-volume workflows that require simultaneous treatment of multiple samples. The accessory supports organised loading, stable tube positioning during shaking and efficient changeover within the RS-TS ecosystem, helping keep heating and cooling thermoshaker setups flexible across day-to-day experimental schedules.

Questions about Interchangeable block, for 8 test tubes, bore Ø 13.5 mm, 1 pc
What is this article?
Interchangeable block, for 8 test tubes, bore Ø 13.5 mm, 1 pc is the article on this page. Luminix Health distributes Phönix Instrument 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.
