Description
Adapter for 1 × 25 mL conical vessel is a centrifuge accessory configured to accept a single 25 mL conical tube measuring 25 mm × 100 mm. It is intended for use in 100 mL round buckets of rotor A-4-38, providing a defined fit between the conical vessel and the bucket geometry during centrifugation. The set is packed as 2 pieces so that both positions of a paired bucket arrangement can be equipped consistently. This format supports laboratories that process samples in 25 mL conical tubes on the A-4-38 rotor platform. Pack data list a net weight of 0,143 kg, a gross weight of 0,158 kg and a packaging volume of 0,001 m³. The adapter (Eppendorf) serves as dedicated interface hardware between the conical 25 mL vessel and the 100 mL round bucket, following the manufacturer’s stated dimensions and rotor assignment. It is classified among centrifuge accessories and is suitable where secure single-tube seating in round buckets is required. Compatibility is restricted to the conical 25 mL format, the given tube dimensions and rotor A-4-38 with 100 mL round buckets as described.
This article is part of Rotor adapters & accessories, in Centrifuges.

Questions about Adapter 1x25ml wrapped (2x)
What is this article?
Adapter 1x25ml wrapped (2x) is the article on this page. Luminix Health distributes Eppendorf 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.
