ProCal Primary Turbidity Standards have been certifiedby HF Scientific for use in the Hach&reg 2100Q Portable Turbidimeter. No formazin is used, making the standards safer, easier to use, accurate and less expensive that the equivalent Hach&reg

T-CAL&reg Turbidity Standards are stable Formazin standards prepared in ready-to-use concentrations to ensure accurate turbidity measurements. All concentrations are verified to meet tight quality control specifications, are EPA & ISO compliant for

High-quality, silica-based adsorbents. Used for common sample matrices such as food and water. Stable over the pH range (2 &ndash 8).

This colorless liquid is the simplest organic nitrile (hydrogen cyanide is a simpler nitrile, but the cyanide anion is not classed as organic). It is produced mainly as a byproduct of acrylonitrile manufacture.
