Applicable for water, soil extracts, or other matrices as specified by manufacturer instructions.

## Long description

ZOOLEK TEST Ca reagent test kit is designed for qualitative or semi-quantitative detection of calcium (Ca) in various sample matrices. The kit contains the chemical reagents and instructions necessary to prepare and perform colorimetric tests that indicate presence and approximate concentration ranges of calcium. It is suitable for laboratory bench work as well as field assessments where a quick check of calcium levels is required, for example in water monitoring, soil extract analysis or other matrices stated in the manufacturer instructions.
Advantages
The reagent test kit provides a straightforward colorimetric method that does not require complex instrumentation, enabling rapid visual assessment of calcium content. Reagents are supplied in a compact format with step-by-step instructions to simplify preparation and testing. The kit’s design allows use both in controlled laboratory environments and on-site, facilitating quicker decision making and preliminary screening before more detailed instrumental analysis.
Suitable for
Rapid screening of calcium in natural and treated water samples
Assessment of calcium in soil extracts and agricultural monitoring
Preliminary checks of calcium in environmental field surveys
Educational demonstrations and basic laboratory exercises involving calcium detection
Key specifications
Detection principle: colorimetric reagent reaction for calcium identification
Result type: qualitative or semi-quantitative visual indication
Intended matrices: water, soil extracts, and other matrices as specified by manufacturer instructions
Kit contents: chemical reagents and user instructions for test preparation and execution
Usage environments: laboratory benchwork and field applications
How to use
Follow the manufacturer instructions included with the kit for reagent preparation, sample handling and test execution. Prepare samples and reagents on a clean surface, add the specified reagent volumes to the sample, and observe any color change according to the provided color chart or interpretation guide. Use appropriate personal protective equipment and handle reagents with care; dispose of used reagents and samples according to local regulations. For semi-quantitative estimation, compare the resulting color with the reference scale supplied in the kit.
Usage recommendations
Use the kit within the shelf-life and storage conditions specified by the manufacturer. For reliable results, avoid contaminated containers and follow sample preparation instructions closely. When precise concentration values are required, confirm preliminary results with a calibrated instrumental method in a laboratory setting.
