AS4-PCR8 Rotor: What the Spec Sheet Establishes for D3024 and D1524R Benches

AS4-PCR8（19400072）

The AS4-PCR8, model 19400072, is listed for use with the D3024 and D1524R centrifuges. That pairing is the first constraint a laboratory should check against its bench inventory.

The stated maximum speed is 15,000 rpm and the stated maximum relative centrifugal force is 21,380 × g. Whether a given protocol reaches those values depends on the run settings and the tubes actually loaded.

Capacity is given as 0.2 mL/PCR8 × 4, meaning four positions for eight-tube PCR strips, or 32 individual 0.2 mL tubes. This suits plate-format and strip-format workflows rather than larger-volume separations.

The rotor body is aluminum alloy and biosealing is indicated as present. Sealing matters when aerosol containment or cross-contamination control is part of the standard operating procedure.

Procurement teams should confirm that the supplied rotor matches the centrifuge model in service and that sealing components are available as separate spare parts. Rotor and seal lifetimes are consumable items that affect long-term cost.

Documentation should be requested for the sealing specification, since the input does not define the containment level or the testing standard behind the claim. Buyers should also verify tube and strip dimensions are compatible with the stated 0.2 mL format.

The real specification is not the maximum speed but the fit between rotor, drive, and protocol — and that fit is verified, not assumed.

Why it matters:
Rotor purchases lock a laboratory into a tube format and a sealing regime. Confirming model compatibility and spare-part supply before ordering avoids a bench that cannot run its own protocols.
