The A8-15P Rotor: A Consumable That Anchors a Benchtop Workflow

A8-15P（19400084）

The A8-15P is a swing-out or fixed rotor assembly identified by part number 19400084. It is stated for use with the DM0424 and DM0408 centrifuge models, which fixes its place in the benchtop preparation workflow rather than in any standalone role.

The listed maximum speed is 4000 rpm. Capacity is given as eight positions of 15 mL, a format common to sample preparation where multiple tubes are processed in a single run to keep batches aligned and reduce handling.

The rotor material is described as high-strength plastic. That is the only material information stated; no autoclave tolerance, chemical resistance, or operating temperature range is provided in the source.

The default adaptor is A15P22. Adaptors determine which tube diameters seat correctly, so the named default establishes a starting configuration rather than a complete compatibility list.

For procurement, the relevant questions are whether the A8-15P is supplied with the A15P22 adaptor or sold separately, whether alternative adaptors exist for other tube formats, and whether the rotor is available as a spare for labs already running DM0424 or DM0408 units.

Documentation matters here. Buyers should verify the maximum rated speed against the specific tube and adaptor combination, since the stated 4000 rpm applies to the rotor as configured, and confirm the correct part number against the centrifuge manual before ordering.

The A8-15P is best read as a model-specific accessory whose value depends on the installed base of DM0424 and DM0408 instruments, not on its specifications alone.

Why it matters:
Rotors are a recurring purchase, so confirming part numbers, adaptor pairing, and stated speed limits before ordering prevents both instrument downtime and mismatched tube formats.
