Description
Adapter for 20 round-bottom vessels of 1,2–5 mL is a centrifuge accessory engineered for 500-mL rectangular buckets used in Rotor A-4-81 and Rotor S-4x500. It holds twenty smaller sample tubes securely inside each large bucket, enabling efficient multi-tube runs without sacrificing balance or tube stability. The volume range covers common laboratory formats from 1,2 mL up to 5 mL round-bottom vessels, making the adapter suitable for routine sample preparation, clinical workflows and research centrifugation. Supplied as a matched pair of two pieces, the set supports symmetrical loading of opposing buckets. This accessory from manufacturer Eppendorf integrates directly with the corresponding rectangular bucket systems, helping laboratories maximise rotor capacity while maintaining reliable tube retention at speed. Net weight is 0,514 kg and packaging volume is 0,003 m³. Straightforward insertion and removal of tubes streamline daily handling, and the dedicated geometry reduces the risk of tube movement during acceleration and braking. Ideal for labs that process batches of culture tubes, collection tubes or similar round-bottom formats and require consistent, reproducible centrifugation results with established Eppendorf rotor platforms.

Questions about Adapter 20x5ml, 2 pcs.
What is this article?
Adapter 20x5ml, 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.
