Cobalt Chloride Extra Pure is a high-purity, pink to deep purple crystalline compound widely used in laboratories for analytical, inorganic, and coordination chemistry. It is especially valued as a humidity indicator, turning from blue (anhydrous) to pink (hydrated) depending on moisture levels. In research settings, it serves as a precursor for synthesizing other cobalt compounds, as well as a reagent in qualitative tests for water, ammonium ions, and complex formation studies. Its extra pure grade ensures precise, contamination-free results, making it ideal for experiments requiring high accuracy. Proper handling with gloves and storage in airtight containers are recommended due to its toxic and moisture-sensitive nature.

Contact key

Product Description The Contact Key is a fundamental switching device used in electrical circuits to manually open or close the flow of current. Commonly used in physics laboratories for demonstration and experimentation with circuits, it enables controlled activation of current for brief or sustained durations. Made from durable, conductive metals with insulating bases, Contact Keys are essential components in circuit testing, timing devices, and low-voltage experimental setups.
