Market Valuation by Listing Type

Median is the primary statistic — used clinical pricing is full of outliers and the median ignores them.

No comp data yet. Collecting listings.

Prices are based on publicly observed listing data — not appraisals. Always verify device condition, service history, and regulatory status before purchase.

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).
