Description
Adapter for 5 × 7 ml round-bottom vessels is a centrifuge accessory that holds five tubes in the 2–7 mL working range with outer dimensions of 12,5 mm × 100 mm. Designed for 100 mL round buckets in rotor A-4-38, it provides secure seating of medium-volume round-bottom tubes during swing-bucket centrifugation. The pack contains 2 pieces and is suited to clinical diagnostics, sample preparation and general laboratory workflows that require simultaneous processing of several 2–7 mL vessels. Manufactured by Eppendorf, the adapter aligns with established A-4-38 rotor configurations used across research and medical laboratories. Net weight is 0,140 kg and gross weight 0,155 kg, offering a compact form factor for convenient installation and storage. By matching the 12,5 mm diameter and 100 mm length of the tubes to the geometry of the 100 mL buckets, the accessory supports balanced loads and consistent sample orientation. It is grouped with centrifuge accessories and is intended for laboratories already operating compatible rotors and round cups.
This article is part of Rotor adapters & accessories, in Centrifuges.

Questions about Adapter 5x7ml wrapped (2x)
What is this article?
Adapter 5x7ml wrapped (2x) is the article on this page. Luminix Health distributes Eppendorf for laboratory use. It sits in Rotor adapters & accessories, inside Centrifuges, in Lab instruments.
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.
