Description
Adapter for one 250 mL bottle in a 500 mL rectangular bucket enables secure centrifugation of mid-volume bottles in matching high-capacity rotors. Each adapter holds one bottle in the flat 180–250 mL range or conical 175–225 mL range; conical bottles must be used together with the conical form inserts supplied by the bottle manufacturer. The adapters fit 500 mL rectangular buckets in rotor A-4-81 and rotor S-4x500 from manufacturer Eppendorf. Delivered as two pieces packed together, they support laboratories that process culture media, buffers, or other liquids in these bottle formats without changing to a different rotor family. Correct pairing with the specified rectangular buckets and, where applicable, conical inserts is essential for proper seating during the run. Net weight is 0,450 kg and gross weight 0,500 kg, with a packaging volume of 0,003 m³. Originating from Germany, these centrifuge adapters belong to standard rotor accessories for bottle work on A-4-81 and S-4x500 systems in research and bioprocess support laboratories.
This article is part of Rotor adapters & accessories, in Centrifuges.

Questions about Adapter 1x250ml f.500ml verp(2x)
What is this article?
Adapter 1x250ml f.500ml verp(2x) 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.
