SA05P2 Rotor Adapter: Matching Small Tubes to the A08-2 Rotor

SA05P2（19400026）

A rotor’s tube capacity is fixed by its bore dimensions. Adapters reconcile that fixed geometry with smaller vessel sizes, letting one rotor handle more than one tube format.

The SA05P2 is listed as a 0.5mL rotor adapter for use with the A08-2 rotor. That pairing is the core specification: tube volume, rotor model, and nothing further.

Packaging is stated at eight pieces per pack, matching the eight-place format implied by the A08-2 designation. Labs running partial loads should account for spare units.

The model number 19400026 is the ordering key. Buyers should confirm it against the rotor’s accessory list before purchase, since adapters are not interchangeable across rotor families.

Compatibility beyond the stated A08-2 rotor is not documented in the listing. Tube geometry, wall thickness, and whether capped or uncapped tubes are acceptable remain open questions.

For procurement, the practical risk is ordering adapters that fit the rotor but not the tubes in use. Requesting the rotor’s accessory documentation resolves that before the order is placed.

Small consumables like adapters determine whether an existing rotor stays in service or forces a new purchase. The specification sheet, not the price, is the deciding document.

Why it matters:
Adapter purchases fail on unverified tube fit, not on availability. Confirm the A08-2 rotor pairing and the exact 0.5mL tube profile with the supplier before ordering.
