Materials:
- Freshly enucleated (removed) eyeball
- Preserving solution (e.g., 10% formalin, 70% ethanol, or a mixture of ethanol and glycerin)
- Glass jar or container with a tight-fitting lid
- Dissecting tools (optional)
- Gloves and safety goggles (for protection)
Procedure:
1. Safety First: Ensure you wear gloves and safety goggles to protect yourself from any potential splashes or biohazards.
2. Enucleation: If the eyeball is not already removed from the animal's head, carefully enucleate it using dissecting tools or gently pry it out. Avoid damaging the eyeball during the process.
3. Cleaning: Gently rinse the eyeball with cool water to remove any traces of blood or tissue debris. Be careful not to apply excessive pressure.
4. Preserving Solution: Choose a suitable preserving solution for your purpose. Formalin is commonly used but may require additional safety precautions due to its toxicity. Ethanol or a mixture of ethanol and glycerin can also be effective.
5. Immersion: Place the eyeball in the chosen preserving solution, ensuring it is fully submerged. The solution should cover the eyeball by at least half an inch.
6. Labeling: Clearly label the jar with the animal species, date of preservation, and type of preserving solution used. This information is crucial for documentation and future reference.
7. Storage: Store the jar in a cool, dark place, away from direct sunlight and extreme temperatures. Proper storage conditions help to prevent deterioration and maintain the preservation.
8. Long-Term Care: Periodically check the preserving solution. If it evaporates or becomes cloudy, replace it with fresh solution to ensure proper preservation.
Remember that this is a general overview of the process, and the exact steps may vary depending on the species and specific circumstances. If you're unfamiliar with eyeball preservation, consider consulting a professional biologist or a taxidermist with experience in these techniques. Preserving eyeballs requires precision and a proper understanding of safety measures.
