Seawater Calcium Test Kit

Overview

Calcium is essential for growth of all calcium depositing organisms. This kit allows the determination of the calcium concentration in seawater at a resolution of 20 mg per liter. Calcium is not stable and the addition of buffers may cause a loss in calcium whereas the use of ion exchange resins may cause a rise in calcium. With this kit the precise amount of calcium may be determined and adjustments can then be made to achieve the nominal level (or slightly higher) that is found in seawater. The kit includes three reagents and deionized water. The dry reagent powder pillows are sufficient for 10 tests. The liquid reagents are sufficient for more than 50 tests at the nominal calcium level. We also offer refills for this kit.
