Description
Adapter 4 × 7 mL Vacutainer is a centrifuge bucket insert configured for four round-bottom vessels in the 2,6 – 7 mL range with tube dimensions of 13,5 mm × 100 mm. It is intended for the 100 mL round buckets of rotor A-4-38, allowing blood-collection and similar Vacutainer-format tubes to be centrifuged in a defined, stable arrangement. The set comprises two adapters, so both buckets of a paired swing-out setup can be equipped consistently. Net weight is 0,144 kg and gross weight 0,160 kg, with a packaging volume of 0,001 m³. Manufactured by Eppendorf, this accessory supports routine clinical and research workflows on compatible 5702-series centrifuge rotors where multiple small-volume tubes must be processed together. The geometry matches standard 13,5 mm diameter collection tubes up to about 100 mm length, helping maintain balance and correct seating inside the round bucket. Origin is Germany (Saxony). Use is limited to the stated vessel sizes and the A-4-38 100 mL round-bucket format described by the manufacturer.

Questions about Adapter 4x7ml wrapped Vacut. (2x)
What is this article?
Adapter 4x7ml wrapped Vacut. (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.
