Description
Holder for 4 test tubes 29–37 mm is a laboratory fixture for securing larger-diameter tubes during vortex agitation. It holds four tubes with outer diameters from 29 to 37 mm, enabling controlled mixing of samples that require wider vessels than standard small-tube racks. Intended for the Vortex-Genie® series, the accessory supports resuspension, blending and short-term agitation steps common in clinical, biochemical and research laboratories. Delivered as one piece and weighing 0,020 kg, it remains a compact, low-mass attachment that can be fitted when larger tubes must be processed together. The four-position layout helps organise parallel work with culture tubes, centrifuge-style vessels or comparable labware within the specified diameter window. Manufacturer Scientific Industrie supplies this holder as part of the Vortex-Genie® accessory range for vortexers and small shakers. It is suited to bench protocols where stable multi-tube retention improves handling consistency and reduces the need to vortex oversized tubes one by one during routine sample preparation.

Questions about Holder for 4 test tubes 29 - 37 mm, For Vortex-Genie® series, 1 unit(s)
What is this article?
Holder for 4 test tubes 29 - 37 mm, For Vortex-Genie® series, 1 unit(s) is the article on this page. Luminix Health distributes Scientific Industrie 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.
