LabChem® Copper Sulfate, Spgr 1.186 @ 18.4C

LabChem® COPPER SULFATE, SpGr 1.186 @ 18.4C is a copper sulfate solution prepared to a precisely defined specific gravity of 1.186 at 18.4°C, the historic basis of the copper sulfate specific gravity screening test used to estimate hemoglobin/blood density in blood donor screening. When a drop of blood is placed in the solution, whether it sinks or floats within a defined time indicates whether the donor meets the minimum hemoglobin threshold. Its precisely controlled density is what makes the test work.

It is used in blood banking and donor screening settings to perform a rapid specific gravity screen for adequate hemoglobin prior to blood donation. Its tightly controlled specific gravity supports consistent, reliable screening results. This reagent should be handled, stored, and used according to established laboratory safety procedures and the manufacturer's instructions.
