Marble Chips 2–4mm – 3kg (Calcium Carbonate for Reaction Rate Experiments)

These high-quality Marble Chips (Calcium Carbonate) are supplied in a 3kg pack with a fine 2–4mm particle size, making them ideal for experiments that require a rapid reaction rate due to increased surface area. With Laboratory Reagent (LR) grade quality, they deliver consistent and reliable performance in educational laboratory settings.

Perfect for acid–carbonate reactions, these smaller chips enable faster production of carbon dioxide gas, making them particularly useful for studying how surface area affects reaction speed. Their uniform size ensures repeatable and accurate results, supporting controlled scientific investigations. Clearly identified with CAS No. 471-34-1, this product meets standard laboratory specifications.

Supplied in a secure, easy-to-handle container, these marble chips are a practical and cost-effective solution for busy school science departments.
