What to know when buying a used lab pumps

General buyer information. Not clinical, regulatory, or safety advice — always confirm with the seller and verify independently.

  • Ask the seller for photos of the serial-number plate, the manufacture year, and any visible damage.
  • Look up the FDA recall record for this specific model + serial range before you buy.
  • Get the seller to confirm what's included in writing (accessories, manuals, cables, software).
  • If buying remotely, arrange a video call or in-person inspection before sending payment.

Recorded asking-price intelligence — not an appraisal, not medical or regulatory advice, independent of and not endorsed by any marketplace. Verify condition, service history, regulatory status, and seller claims independently.

We are paid to value equipment, never to trade it — no fee we earn moves with the number we report or with what your equipment later sells for.

Library figures are estimates based on recorded listing data. They are not appraisals and not guaranteed sale prices. A signed, dated, USPAP-conformant appraisal is a separate engagement. The library publishes 231,081 equipment price points across 9 marketplaces, with medians for 44 device classes. Refreshed every 24 hours. Every datapoint links back to its source.

Independent of, and not endorsed, sponsored, certified, or authorized by — and not an agent of — any marketplace, manufacturer, or source.
