Beschreibung
Adapter 9 × 7 ml is a centrifuge adapter for nine round-bottom vessels in the 2,6–7 mL range. It fits 100 mL rectangular buckets used in rotor A-4-44 and provides secure positioning of intermediate-volume tubes during laboratory spin protocols. Delivered as two pieces per pack, the adapter allows balanced dual-bucket operation and simplifies switching between tube formats without exchanging the rotor. This accessory is from manufacturer Eppendorf and is intended for centrifuges configured with the A-4-44 rotor and corresponding rectangular buckets. Net weight is 0,280 kg and gross weight 0,311 kg, with a packaging volume of 0,002 m³, so the set is practical for storage beside the instrument. Laboratories use such adapters for sample concentration, phase separation, washing steps and routine preparation work in life-science, analytical and clinical settings where 2,6–7 mL round-bottom vessels are standard. The nine-place layout supports efficient batch handling while maintaining alignment under centrifugal force, helping operators keep workflows consistent across repeated runs and shared instrument schedules.
This article is part of Rotor adapters & accessories, in Centrifuges.

Questions about Adapter 9x7ml, verp.
What is this article?
Adapter 9x7ml, verp. is the article on this page. Luminix Health distributes Eppendorf for laboratory use. It sits in Rotor adapters & accessories, inside Centrifuges, in Präzisionsinstrumente.
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.
