We're tracking 7 active Watson-Marlow 313S listings across 1 source, but we don't have enough complete-system comps to publish a median yet. Parts and modules are tracked separately — for parts / repair (1 comp · median $144) — 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.

What does a used Watson-Marlow 313S cost?

About this guide: Prices reflect publicly observed listings, not verified sales. Condition, configuration, and seller drive most of the variance. Clinical Asset Index does not broker, sell, inspect, or appraise. See methodology for full criteria. Confidence tiers: Firm = ≥5 CS listings; Limited = 1–4; Collecting = 0.
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.
