Selection resolves a path: a rotor, the adapter it needs, and the specific tube dimensions the manufacturer lists for that combination — then checks the path-specific RCF where it is published; otherwise the configuration is flagged for confirmation. The same rotor can carry two different radii depending on the adapter, and therefore two different maximum RCF figures. The filter tests capability (the path can reach at least the RCF you set), not that a given model can be dialled to exactly that value. The DM0506 brochure also lists 7, 10 and 20 mL capacities; tube dimensions and adapter configurations for those are not published in the supplied sheet, so they are not included in the automatic filter — ask us if you need them. Selection does not account for temperature control, throughput, footprint or budget — read the product page before deciding, and confirm the configuration at quotation.

The manufacturer publishes a single operating point for this model — a maximum speed with continuous, lid-activated operation — and does not publish a user-selectable speed range, minimum speed or speed increment. The slider is therefore locked to the published maximum.

This speed is above the manufacturer’s maximum for the selected rotor. Never exceed the rated speed of a rotor.

Model: RCF = r · ω² / g with ω = 2πN/60 and g = 9.80665 m/s², which is equivalent to RCF = 1.118 × 10⁻⁵ · r[cm] · N². Each configuration carries its own radius, labelled published where the manufacturer states it and derived where it is back-calculated from the published maximum speed and RCF. Neither value was independently measured by ACS Material. The plotted curve is anchored to the manufacturer-published maximum pair: RCF(N) = RCF_max × (N/N_max)²; the displayed radius is retained as source information rather than used to generate the curve. Adapter configurations for which the manufacturer publishes neither a radius nor a path-specific RCF are excluded from this calculator entirely and appear only in the selector, flagged for confirmation. Curves are drawn only across each model’s published speed range; the region below the published minimum is shaded as no-data, and a model with a single published operating point is drawn as a point, not a curve. Real RCF varies with the actual radius at which the sample sits, tube geometry and load. A schematic teaching tool — always follow the instrument manual and the rotor’s rated limits.
