A2P17(Optional)（19500023）
Centrifuge adapters rarely headline a procurement list, yet an unmatched insert can idle an entire rotor. The A2P17 adapter, catalog 19500023, is a case in fitment rather than performance.
The A2P17 is listed as an adapter for 1.5 mL and 2 mL cryogenic vials and centrifuge tubes, supplied 24 pieces per pack. It carries model number 19500023.
The listed compatible equipment is specific: S4-50, S6-15, A24-15P, A12-10P, and A6-50P. Those codes correspond to rotors and adapter sets, not to the centrifuge itself.
The title marks the item optional, which suggests it is an accessory rather than part of a base configuration. Buyers should confirm whether their existing rotor accepts it.
The 24-piece pack size matters in practice. Adapters are consumed, lost, and autoclaved in batches, so pack quantity drives reorder rhythm as much as unit price.
Compatibility across 1.5 mL and 2 mL formats is stated in the listing, but dimensional tolerances against specific vial brands are not. That gap belongs in a pre-purchase question.
The input provides no material, temperature rating, sterilization method, or certification. Any of these may be documented elsewhere, or may not exist.
Small accessories expose supply-chain thinness. A rotor with a single vendor for its inserts is a single point of failure.
Why it matters:
Verify rotor fitment and request documentation on material and sterilization before ordering; the listed codes, not the centrifuge model, determine whether this pack works.
