Providence, RI — Verichem Laboratories now offers clinical laboratory professionals a broad selection of ready-to-use, liquid stable carbon dioxide (CO2) reference standards. Intended for calibration, or calibration verification, these versatile products are compatible with both ion selective electrode (ISE) and “wet chemistry” testing methodologies and are expressly designed to support overall system QC and CLIA compliance, as the materials meet the necessary CLIA requirements for verification materials with known values in the determination of a clinical system’s accuracy, sensitivity, linearity, and reportable range.

Verichem Laboratories’ CO2 reference standards are packaged in ready-to-use, translucent polyethylene dropper vials, with a fifteen milliliter (15.0mL) fill at each level. The unique liquid stable format is free of glycols, surfactants, azides, and other interfering substances and is prepared from pure reagent grade source materials; with each concentration level verified using sodium carbonate Alkalimetric Standard, meeting the reagent grade designation as specified by the American Chemical Society (ACS). In addition, all of these CO2 reference standards feature an exceptional open-vial stability (15 months), display negligible lot-to-lot variation, and contain a certificate of analysis  within each kit indicating traceability data for that particular lot. 

Verichem Laboratories serves the clinical laboratory testing and in vitro diagnostic (IVD) manufacturing markets with a comprehensive line of calibration verification products, chemistry standards, reference materials, and support services, including free, instant online data reduction reports for CLIA compliance.
