Description
Adapter for 4 × 20 mL round-bottom vessels is a centrifuge accessory designed for 90 mL rectangular buckets in rotor A-4-38. It holds tubes with dimensions 22 mm × 100 mm and is supplied as a pack of two pieces. The arrangement allows four 20 mL round-bottom sample vessels to be centrifuged together inside the matching rectangular bucket, supporting orderly sample handling on the A-4-38 rotor system. From manufacturer Eppendorf, these adapters suit centrifuge setups that already employ 90 mL rectangular buckets, so additional vessel formats can be used without altering the rotor. Net weight is 0,180 kg and gross weight 0,200 kg, with a packaging volume of 0,001 m³, keeping the set compact among other rotor accessories. Originating from Germany, the product forms part of the centrifuge accessories range and is intended for secure placement of round-bottom vessels during standard laboratory spin protocols. The two-piece pack provides a practical stock level for routine workflows that require consistent tube alignment within the 90 mL buckets of rotor A-4-38.
This article is part of Rotors, in Centrifuges.

Questions about Adapter 4x20ml verpackt (2x)
What is this article?
Adapter 4x20ml verpackt (2x) is the article on this page. Luminix Health distributes Eppendorf for laboratory use. It sits in Rotors, inside Centrifuges, in Lab instruments.
A centrifuge rotor is the rotating part that holds the tubes, and it is rated for a maximum speed and a maximum load. A swing-out rotor and a fixed-angle rotor pellet differently. A rotor from another centrifuge does not belong on this drive, even when it seems to fit.
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.
