Mesa Labs offers Steam and EO D-value or Survival/Kill testing in state-of-the-art BIER Vessels. D-value procedures used follow USP/ISO and can be obtained via Spearman Karber (fraction negative) method, Survivor Curve (direct enumeration) or with Stumbo-Murphy-Cochran. Mesa Labs can inoculate and perform D-value analysis on small items (e.g. coupons or stoppers) or we can verify a competitor’s claim for D-value, z-value, and population.
