Description
Adapter for 18 round-bottom vessels of 2,6–7 mL is designed for 500-mL rectangular buckets in Rotor A-4-81 and Rotor S-4x500. It accommodates eighteen tubes in the Vacutainer-compatible volume range, allowing laboratories to process larger numbers of blood-collection or similar round-bottom tubes in a single centrifugation cycle. The adapter seats tubes firmly within the rectangular bucket geometry, supporting balanced operation and secure retention throughout the run. Delivered as a set of two pieces, it enables paired loading of opposite buckets for correct rotor balance. This accessory from manufacturer Eppendorf is intended for routine clinical, diagnostic and research environments that rely on the A-4-81 or S-4x500 rotor platforms. Net weight is 0,540 kg with a packaging volume of 0,003 m³. The dedicated multi-tube layout improves throughput compared with single-tube handling while remaining simple to load and unload. Laboratories working with 2,6–7 mL round-bottom formats benefit from standardised positioning that contributes to reproducible separation results and efficient use of available rotor capacity on matching Eppendorf centrifuge systems.

Questions about Adapter 2,6-7mL Vacu.500mL rectan. 2 pcs
What is this article?
Adapter 2,6-7mL Vacu.500mL rectan. 2 pcs 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.
