AS24-2 Rotor: Reading a Benchtop Centrifuge Spec Sheet

AS24-2（19400069）

The AS24-2 is identified by model number 19400069. Its stated maximum speed is 15,000 rpm, with a maximum relative centrifugal force of 21,380 × g. Those two figures describe the spinning envelope, not a guaranteed separation result for any particular sample.

The rotor holds 24 positions. The listed capacities cover 2 mL, 1.5 mL, 0.2 mL and 0.5 mL tubes across those positions, so the same body accommodates different tube formats. The rotor is made of aluminum alloy and is listed as biosealing.

Two rotor adapters are named: A02P2 and A05P2. The listing does not state which tube sizes each adapter serves, so that mapping has to be confirmed before ordering.

Biosealing matters when samples carry infectious or hazardous material, because it changes how the rotor is handled and decontaminated. What the seal specifically covers is not described here.

For procurement, the practical questions are the centrifuge model the rotor fits, the adapter-to-tube pairing, and whether the 15,000 rpm rating applies with every listed tube size loaded. None of that is settled by the listing alone.

Documentation should also confirm rotor lifetime, inspection intervals, and whether the biosealing claim is certified. A rotor is a wear item with a defined service life, and that record travels with the lab’s safety file.

The useful signal here is the capacity range, not the peak numbers. A rotor that spans 0.2 mL to 2 mL reduces the number of accessories a lab must stock, which simplifies ordering more than a higher top speed does.

Why it matters:
Buyers should verify centrifuge compatibility, adapter mapping, and rotor service documentation before purchase. The listed speed and RCF apply only within the manufacturer’s stated operating conditions.
