Description
Rack 1 × 500 ml D98 mm FB is a centrifuge accessory configured to hold one 500 ml vessel with a 98 mm diameter in a flat-bottom (FB) arrangement. Supplied as a two-piece pack, the rack supports secure placement of larger-volume containers during centrifugation and related sample-processing steps. Product type is Centrifuge Accessories; display devices are not included. Net weight is 0,4 kg and gross weight is 0,6 kg per supply unit, with packaging depth 0,28 m, width 0,18 m, height 0,11 m and packaging volume 0,006 m³. This rack from manufacturer Ohaus is intended for laboratories that process 500 ml flat-bottom formats and require a matching rotor or bucket interface accessory. Country of origin is Germany. The defined 98 mm diameter and single-position 500 ml layout help maintain correct vessel seating and balance considerations when running larger liquid volumes. It fits workflows in biotechnology, chemistry and quality-control laboratories where robust centrifuge racks for 500 ml FB vessels are needed as replaceable or supplementary accessories alongside existing centrifuge systems.
This article is part of Rotor adapters & accessories, in Centrifuges.

Questions about Rack 1x500ml D98mm FB 2/pk
What is this article?
Rack 1x500ml D98mm FB 2/pk is the article on this page. Luminix Health distributes Ohaus 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.
