Description
Adapter for 25 × 5 ml tubes is a centrifuge bucket insert designed to hold 25 round-bottom vessels in the 2,6–5 mL volume range. It is intended for use with 500 mL rectangular buckets in rotor A-4-81 and rotor S-4x500, enabling higher tube counts when processing smaller sample volumes in large swing-out buckets. Each unit positions multiple round-bottom tubes securely for balanced centrifugation within the rectangular bucket geometry. The set is packed as 2 pieces, so both sides of a swing-bucket rotor can be equipped symmetrically for matched loading. Net weight is 0,495 kg and gross weight 0,550 kg, with a packaging volume of 0,003 m³. This adapter pair from manufacturer Eppendorf supports flexible sample formats on compatible 500 mL rectangular-bucket rotors without changing the primary rotor, making it a practical accessory for laboratories that alternate between larger bottles and smaller 2,6–5 mL round-bottom tubes on the same centrifuge platform.
This article is part of Rotor adapters & accessories, in Centrifuges.

Questions about Adapter 25x7ml (2x)
What is this article?
Adapter 25x7ml (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.
