Adapter for 1 × 7 ml tubes, D13 mm RB/Vac/Sar is a dedicated centrifuge accessory that securely positions a single 7 ml tube of round-bottom, Vacutainer or Sarstedt type during centrifugation. The adapter is dimensioned for a tube diameter of 13,5 mm and is supplied as a convenient pack of two pieces, allowing balanced rotor loading or spare capacity in busy laboratories. Net weight is only 0,032 kg per set, while the packed unit weighs 0,169 kg and occupies a compact volume of 0,003 m³ (0,21 m × 0,18 m × 0,09 m). These physical characteristics make the accessory easy to handle, store and transport between workstations. Suitable for routine sample preparation, clinical chemistry and research workflows that rely on 7 ml tubes, the adapter ensures stable tube seating and consistent results. Produced by manufacturer Ohaus, it belongs to the centrifuge-accessories product group and originates from Germany. The design supports repeated use in standard laboratory rotors without additional display or electronic components, focusing purely on reliable mechanical tube retention for everyday centrifugation tasks.

Questions about Adapter 1x7ml D13mm RB/Vac/Sar 2/pk
What is this article?
Adapter 1x7ml D13mm RB/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 Instrumenten.
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.
