Large volume packaging for multiple events. Reusable 5 to 15 mL vials with extended stability The Verichem Advantage Each Verichem kit is designed for concentration accuracy based on available definitive method value assignment traceable to NIST, USP or reference methods. This unique design provides universal product compatibility with all wet chemistry methods. Learn More Remarkable optical clarity Suitable for most methods - visible and UV, kinetic or endpoint Known concentrations for calibration or calibration verification Constant protein content and pH across the concentration levels Glycol and azide free Stable 21 months from date of manufacture View Kit Protein-based, liquid gravimetric standards Intended for calibration verification or calibration Suitable for diluted (indirect) ISE and cesium flame Glycol and surfactant free for maximum electrode protection Extended range for high volume analyzers View Kit Compatibility Verichem Products are suitable for most diagnostic, wet chemistry analyzers and are not custom designed for any one analyzer. This is a cost-effective design strategy that allows us to produce larger lots and keep manufacturing costs to a minimum. In some cases, you may need to dilute between concentration levels to obtain a lower value at the upper end of the assay range where linearity falls off. Your verification range can be customized and extended for certain analytes by using the optional Level (F).
