The unit measures 178 mm in width, 127 mm in depth and 102 mm in height, with a net weight of 1,4 kg that supports stable placement on compatible platforms. Supplied as one piece, it forms part of modular shaking setups built around durable stainless steel universal platforms available in numerous sizes and configurable for secure mounting of tube racks and flask clamps. This accessory from manufacturer Ohaus helps laboratories increase throughput when paired with broader or stackable platforms and an extensive clamp range covering volumes from 10 ml to 6 l. Stainless steel clamps are intended for glass flasks, while PVC clamps suit polycarbonate flasks and are autoclavable. Adjustable bar platforms and wide vessel carriers with padded bars accommodate irregularly shaped sample containers, wide vessels and glass balloons.

Questions about Test Tube Rack 22-25 mm Diameter
What is this article?
Test Tube Rack 22-25 mm Diameter 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.
