Calcium Carbonate Standard, 1000 ppm (1 mL = 1 mg CaCO₃)

The solution is meticulously prepared to the industry-standard concentration, providing a precise reference point where 1 mL equals 1 mg of Calcium Carbonate (CaCO₃), which is equivalent to 0.4 mg of Calcium (Ca). This direct relationship simplifies calculations and ensures the accuracy of your titration standards. By choosing this ready-to-use formulation, you eliminate the time-consuming and error-prone steps of preparing and standardizing the primary standard in-house, guaranteeing consistent and reliable results for environmental and industrial water analysis.

Features:

• Primary standard solution for water hardness determination (EDTA titrations)
• Precisely standardized to 1 mL = 1 mg CaCO₃ (and 0.4 mg Ca)
• Eliminates time-consuming preparation steps and ensures consistent concentration
• Ideal for instrument calibration and reliable quality control in environmental and water treatment testing
• Manufactured by LabChem Inc. for certified quality and reliability
• Available in 125 mL and 500 mL sizes
