The specific gravity of zinc sulfate solution, specifically the formulation used for the concentration of intestinal parasites, eggs, and cysts, is 1.180.
Specific gravity is a dimensionless quantity that represents the ratio of the density of a substance to the density of a reference substance, typically water at a specified temperature (often 4°C or 20°C). For solutions like zinc sulfate, specific gravity is a crucial property, indicating its concentration and density relative to water. A specific gravity greater than 1 means the solution is denser than water.
The provided reference highlights a specific zinc sulfate solution, manufactured by Ricca Chemical and available through Fisher Scientific, which has a precisely measured specific gravity of 1.180. This particular value is not arbitrary; it is carefully chosen for its intended application: the effective separation and concentration of various parasitic elements.

Practical Insights:
- Parasite Flotation: The specific gravity of 1.180 is ideal for the flotation technique in parasitology. This method relies on the principle that many parasite eggs and cysts are less dense than the zinc sulfate solution. When fecal samples are mixed with this solution and centrifuged, the denser fecal debris settles at the bottom, while the lighter parasite eggs and cysts float to the surface, making them easier to collect and identify under a microscope.
- Optimized Performance: This specific gravity ensures optimal separation, preventing lighter eggs from being trapped by denser debris and heavier eggs from sinking. It represents a balance that maximizes the recovery of a broad range of common intestinal parasites.
- Quality Control: For laboratories, using a zinc sulfate solution with a verified specific gravity like 1.180 from reputable suppliers ensures consistency and reliability in diagnostic results. It's a critical parameter for standardizing laboratory procedures.
In summary, the specific gravity of 1.180 for zinc sulfate solution is a precise measurement vital for its role in diagnostic procedures, particularly for the concentration of intestinal parasites, eggs, and cysts.
