Description
Adapter 3 × 7 ml (75 mm), 2 pieces is a centrifuge adapter for three round-bottom vessels in the 2–5 mL range with dimensions 13 × 75 mm. Each adapter positions three tubes side by side, enabling efficient multi-tube runs in compatible fixed-angle rotors. The set comprises two adapters and is specified for rotor F-34-6-38, supporting standardised loading of smaller round-bottom tubes in research and routine laboratory centrifugation. Physical fit to the 13 × 75 mm tube format helps maintain stable tube alignment during acceleration and braking. These adapters from manufacturer Eppendorf form part of the centrifuge accessory portfolio for the F-34-6-38 rotor family. Pack net weight is 0,112 kg (gross 0,124 kg), suitable for everyday bench and instrument use. Laboratories processing 2–5 mL round-bottom samples can expand capacity per run while keeping rotor and instrument configurations consistent across clinical, molecular and general analytical workflows that rely on compact tube formats.
This article is part of Rotor adapters & accessories, in Centrifuges.

Questions about Adapter 3x7ml (75mm), 2 pcs.
What is this article?
Adapter 3x7ml (75mm), 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.
