Methodology

Clinical Asset Index aggregates listing data from eBay, GovDeals, DOTmed, HiBid, LabX, and PublicSurplus daily. Each listing is classified by type (complete system, major module, part / accessory, for parts / repair). Medians and ranges are computed only within peer groups — a complete system is never averaged with parts. Confidence thresholds: comps ≥ 0.65; deal-feed device-match ≥ 0.75 and classification ≥ 0.65. Median is the primary statistic; the mean is shown only as a small secondary number because outliers dominate this market. Data is directional — always verify independently before purchase.

What to verify before buying

Generic checklist for lab equipment — these are the items that drive the largest price variance.

Confirm the listing is a complete system, not a part or accessory.
Request service history and the date of the last preventive maintenance.
Verify condition independently before purchase - condition drives the largest price variance.
Confirm the seller is the actual holder of the equipment (vs a broker).
