FA12-2P(19400134): What the Rotor Specs Reveal About Lab Centrifuge Procurement

FA12-2P(19400134)

The FA12-2P is listed for the D1012UA model, with a maximum speed of 12,000 rpm. That figure is the rotor’s rated ceiling, not a recommended operating point; actual protocols depend on tube type, fill volume, and the centrifuge’s own limits.

Stated capacity covers 12 positions for 0.5, 1.5, or 2 mL tubes, plus four 0.2 mL 8-strip PCR tubes. The same rotor is also listed for 44 individual 0.2 mL PCR tubes, indicating a swing or adapter arrangement that changes the usable format.

The rotor material is ABS engineering plastic. Buyers should confirm chemical compatibility with the reagents and decontamination agents in use, since plastic rotors are not interchangeable with aluminum or composite equivalents in every protocol.

Compatibility between the rotor and a specific centrifuge model is the decisive check. The listing names the D1012UA, and the model code 19400134 appears as a separate identifier, so procurement should verify which number the supplier treats as the orderable part.

Documentation matters here. A rotor certificate, maximum RCF at a stated radius, and a lifetime or inspection interval are standard expectations for regulated laboratories, and none are given in the source data.

Consumable fit is the second supply-chain question. Tubes from different manufacturers vary slightly in height and cap profile, which affects whether a strip seats correctly and whether the stated 44-tube count is achievable in practice.

Rotor specifications are only a starting point; the purchasing decision rests on the unlisted parameters.

Why it matters:
Confirm the rotor-to-centrifuge fit, the orderable part number, and the ABS chemical compatibility before ordering, since the published listing does not resolve these points.
