We're tracking 3 active Welch CRVpro Direct Drive Vacuum Pump listings across 1 source, but we don't have enough complete-system comps to publish a median yet. Parts and modules are tracked separately — major module (3 comps · median $3,741) — so the complete-system price isn't skewed by mixing categories.
Market Valuation by Listing Type
Median is the primary statistic — used clinical pricing is full of outliers and the median ignores them.

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