Description
Adapter for 8 × 9 mL round-bottom vessels is a centrifuge accessory intended for 90 mL rectangular buckets in rotor A-4-38. It seats tubes with dimensions 14,5 mm × 100 mm and is delivered as a pack of two pieces. The format lets laboratories run multiple 9 mL round-bottom sample vessels together inside the matching rectangular bucket, supporting organised sample handling on the A-4-38 rotor system. From manufacturer Eppendorf, the adapters fit existing centrifuge setups that already use 90 mL rectangular buckets, so vessel choice can be extended without changing the rotor itself. Net weight is 0,180 kg and gross weight 0,200 kg, with a packaging volume of 0,002 m³, making the set compact to store with other rotor accessories. Originating from Germany, this accessory belongs to the centrifuge accessories range and is aimed at secure positioning of round-bottom vessels during routine spin protocols. The two-piece pack supplies a practical quantity for day-to-day laboratory workflows that rely on consistent tube alignment inside the 90 mL buckets of rotor A-4-38.
This article is part of Rotors, in Centrifuges.

Questions about Adapter 8x9ml verpackt (2x)
What is this article?
Adapter 8x9ml 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.
