Description
Rack 38 × 5.5-12 ml D16 mm Vac/Sar is a centrifuge accessory that holds thirty-eight tubes in the 5.5–12 ml range with a 16 mm diameter. The Vac/Sar designation indicates suitability for common Vacutainer and Sarstedt tube formats used in clinical and research centrifugation. Classified as centrifuge accessories, the rack is delivered as a pack of 2 pieces. Net weight is 0,6 kg and gross weight is 0,8 kg. The package measures 0,28 m in depth, 0,18 m in width and 0,11 m in height, with a packaging volume of 0,006 m³. Origin is Germany. Offered by manufacturer Ohaus, this rack supports organised loading of mid-volume blood-collection and sample tubes during spin protocols. Display devices are not part of the product; the focus is reliable tube seating at 16 mm diameter. The two-piece pack helps laboratories maintain spare capacity for high-throughput runs or parallel centrifuge setups without delaying sample processing.

Questions about Rack 38x5.5-12ml D16mm Vac/Sar 2/pk
What is this article?
Rack 38x5.5-12ml D16mm Vac/Sar 2/pk is the article on this page. Luminix Health distributes Ohaus for laboratory use. It sits in Rotor adapters & accessories, inside Centrifuges, in Instruments de laboratoire.
An adapter lets a rotor spun for large tubes accept smaller ones. The adapter has to be the one for that rotor, and the tubes have to be supported at the shoulder the adapter was designed for. A stack of the wrong inserts is an unbalanced load.
A centrifuge separates by density. The rotor spins the sample and the force is reported as a multiple of gravity, not as a raw speed, because the same revolutions per minute are a different force at a different radius. A microcentrifuge takes small tubes. A benchtop or floor model takes larger rotors. The tube, the adapter and the rotor have to be the combination the manufacturer rated. An unbalanced load is how centrifuges fail. Measurement of the related quantities sits with the BIPM.
