Description
Adapter for 4 × 15 mL round-bottom vessels is a centrifuge insert that accommodates four round-bottom tubes in the 9–15 mL range, with tube dimensions 17,5 mm × 100 mm. It fits the 100 mL round beaker of rotor A-4-38 and is supplied packed as two pieces. This configuration increases the number of smaller round-bottom tubes that can be processed per bucket while retaining the standard 100 mL beaker interface of the A-4-38 rotor. The adapters come from manufacturer Eppendorf and are intended as centrifuge accessories for laboratories that alternate between larger beakers and multi-tube layouts. Net weight is 0,130 kg and gross weight 0,144 kg, with a packaging volume of 0,001 m³; origin is Germany (Saxony). Correct seating of four 9–15 mL round-bottom vessels per adapter supports orderly, balanced loading when higher tube throughput is needed in the same rotor. The two-piece pack allows opposite positions to be fitted identically or a spare adapter to be kept available. Geometry 17,5 mm × 100 mm matches the stated round-bottom vessel class for reliable placement inside the 100 mL round beaker.
This article is part of Rotor adapters & accessories, in Centrifuges.

Questions about Adapter 4x15ml wrapped (2x)
What is this article?
Adapter 4x15ml wrapped (2x) is the article on this page. Luminix Health distributes Eppendorf for laboratory use. It sits in Rotor adapters & accessories, inside Centrifuges, in Instruments de laboratoire.
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.
