Description
Adapter 9×D12 is a centrifuge adapter for nine round-bottom vessels of 75 mm length, intended for 90 ml rectangular beakers in rotor A-4-38. With a vessel diameter of 12 mm, the adapter seats Ø12 mm tubes securely inside the corresponding rectangular bucket so multiple small vessels can be processed in one run. The pack contains 2 pieces for balanced rotor loading. Net weight is 0,198 kg and gross weight 0,220 kg, with a packaging volume of 0,002 m³. Country of origin is Germany (Saxony). This adapter from manufacturer Eppendorf is designed specifically for the 90 ml rectangular beaker and A-4-38 rotor combination used on compatible Eppendorf centrifuge platforms. It supports laboratory centrifugation of round-bottom tubes where defined length, diameter and multi-position layout are required. Suitable for research, clinical and routine labs equipping or replacing A-4-38 accessories with genuine 9×D12 adapters supplied as a matched pair.

Questions about Adapter 9xD12 for A-4-38 (2x)
What is this article?
Adapter 9xD12 for A-4-38 (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.
