The A6-50P Rotor: What a 4000rpm Swing-Out Unit Tells Buyers

A6-50P (round bottom）（19100197）

The A6-50P is listed as a round-bottom rotor for the DM0412 centrifuge, carrying model number 19100197. Its stated maximum speed is 4000rpm, with a maximum relative centrifugal force of 1800×g.

Capacity is given as either 50mL×6 or 15mL×6, meaning the rotor accommodates six positions and supports two tube formats. The round-bottom description indicates the tube profile the wells are shaped to accept.

The rotor body is specified as high-strength plastic. That is the full extent of the material information provided.

In practice, the two capacity figures matter more than they first appear. A lab standardising on 15mL conical tubes and one running 50mL round-bottom tubes would be using the same rotor in different configurations, which affects how tube adapters and balance pairs are managed.

For procurement, the input does not state whether the rotor is supplied with the DM0412 or sold separately, nor whether adapters are included. Buyers would need to confirm the rotor-to-tube fit, the correct balance arrangement for six-place loading, and whether the 1800×g ceiling is measured at a specific tube format.

Documentation is equally thin: no compatibility list, no certification, and no service life or inspection interval appears in the source. Those gaps are normal for accessory listings but should be resolved before a rotor enters a regulated workflow.

Where a rotor is a replaceable component rather than a fixed asset, the purchasing decision turns on the specification sheet being complete enough to verify fit, speed, and capacity before the unit arrives.

Why it matters:
A rotor that fits the wrong tube format or is balanced incorrectly can fail under load. Confirming the DM0412 pairing, the tube profile, and the loading configuration is the practical step between the listing and safe operation.
