Biochemical Diagnostics, an "S" corporation, has been manufacturing products for Forensic, Research, and Clinical Laboratories under FDA license since 1981. Prior to 1981, we were a division of Brinkmann Instruments. In 1981 we initiated a buyout of Brinkmann Instrument's clinical division and as they say, "the rest is history". Biochemical Diagnostics is ISO 13485:2003 certified. Many of our products for export carry the CE mark. We manufacture Detectabuse, and Stat-Skreen Toxicology Urine Controls for initial screening, drug confirmation, and hand-held devices. Products include controls manufactured according to SAMHSA guidelines and custom formulations. The controls, in ready-to-use liquid form, are extremely stable with a long shelf life. The Multi-Prep and Detectabuse product lines of disposable, polymeric anion and cation exchange SPE cartridges and 96 well micro-plates flow by gravity. Gravity flow eliminates the need for vacuum or pressure flow assistance making this product line ideal for automation. The economical SP/E workstations include the SP/E-48 which enables up to 48 samples to be processed from extraction through dry-down in less than 45 minutes.
