The SA02P2 Rotor Adapter and the Small-Volume Workflow

SA02P2(19400029)

Centrifuge accessories are specified by fit, not by brand appeal. A rotor adapter only works if its dimensions match both the rotor and the tube it holds.

Small-volume centrifugation depends on adapters that let a standard rotor carry narrower tubes. Without them, a 0.2mL tube cannot be seated securely in a rotor bored for larger vessels.

The SA02P2 is listed as a 0.2mL rotor adapter for use with the A08-2 rotor. That pairing is the core specification: the adapter is not a standalone device and has no function outside a compatible rotor.

The model number 19400029 identifies the item in the supplier’s catalog, and the excerpt lists packaging at eight pieces per pack. Eight units suggests a set sized to fill a rotor positions in one purchase, though the input does not state the A08-2’s position count.

For procurement, the practical question is whether existing A08-2 rotors in a lab are already fitted with adapters or need them replaced. Adapters wear, deform, and go missing, so pack quantity matters for reordering cycles.

Documentation should confirm tube geometry, maximum speed ratings, and material compatibility before purchase. The input provides none of these, so buyers must verify them against the rotor manual.

Supply continuity is the quiet risk in accessory procurement. A rotor without available adapters becomes unusable for small-volume protocols, regardless of its condition.

Accessory fit is the constraint that governs the whole workflow.

Why it matters:
Confirm adapter compatibility with the A08-2 rotor and tube format before ordering. Packaging is eight pieces per pack, so match quantity to rotor capacity and expected replacement rate.
