Description
Adapter 4x18 mL is a centrifuge adapter for four round-bottom vessels with volumes from 7 to 18 mL. It is made for 100 mL rectangular buckets in rotor A-4-44 and comes packed as two pieces. The adapter positions round-bottom tubes correctly inside the rectangular bucket so samples remain stable through the run. This accessory from manufacturer Eppendorf is matched to the A-4-44 rotor and its 100 mL rectangular buckets on compatible laboratory centrifuges. Net weight per pack is 0,279 kg, gross weight 0,309 kg and packaging volume 0,002 m³. Using purpose-built adapters reduces the need for improvised holders when processing mid-volume round-bottom tubes in larger buckets. The two-piece pack equips both sides of a swinging-bucket pair for balanced operation. Suitable for everyday centrifugation tasks in research and routine labs that employ 7–18 mL round-bottom vessels, it provides a defined mechanical fit between tube, bucket and rotor A-4-44 without altering the centrifuge configuration itself.

Questions about Adapter 4x18ml, verp.
What is this article?
Adapter 4x18ml, verp. 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.
