Description
Adapter 80–120 mL is a centrifuge rotor accessory designed to hold round-bottom vessels in the 80–120 mL volume range. It enables secure seating of larger sample containers during centrifugation and is specified for use with rotor A-4-81 and rotor S-4x500. Supplied as a matched set of two pieces, the adapter supports balanced loading when both sides of a swing-bucket rotor are equipped. In routine laboratory workflows this type of insert is used whenever protocols call for medium-volume round-bottom tubes that do not fit the standard bucket geometry directly. Physical data include a net weight of 0,550 kg and a gross weight of 0,612 kg, with a packaging volume of 0,002 m³. The component originates from Germany and is offered from manufacturer Eppendorf as a dedicated rotor accessory for the stated bucket systems. Correct adapter selection helps maintain tube alignment, reduces the risk of imbalance, and allows laboratories to process 80–120 mL round-bottom formats without changing the entire rotor. Ideal for research, clinical, and industrial centrifugation setups that already operate A-4-81 or S-4x500 rotors and need reliable vessel support for this capacity class.

Questions about Adapter 80 - 120mL, 2 pcs
What is this article?
Adapter 80 - 120mL, 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.
