Description
Tube holder kit with lock is a secure, high-capacity accessory for vortex mixers, designed to retain multiple tubes firmly during vigorous agitation. The locking construction keeps the holder positively engaged on the mixer platform, preventing unwanted movement even under high-throughput or extended mixing cycles. Compatible with foam racks that accept tubes from 0,5 ml to 50 ml and diameters typically between 10 mm and 29 mm, the kit supports a wide variety of sample formats used in molecular biology, biochemistry and clinical laboratories. The modular design allows easy customisation and can be combined with multi-tube foam inserts or plate holders to expand capacity. Supplied as a complete set with a net weight of 0,9 kg, the kit offers a robust solution for laboratories that process numerous tubes simultaneously. Manufactured by Ohaus, it forms part of an extensive vortexer accessory portfolio that also includes single- and multi-plate configurations. The locking tube holder improves workflow safety and reproducibility by ensuring consistent sample positioning throughout the mixing process, making it suitable for both routine and demanding high-throughput applications.

Questions about Tube Holder Kit with Retainer
What is this article?
Tube Holder Kit with Retainer is the article on this page. Luminix Health distributes Ohaus 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.
