Preserving with Hand Sanitizer

Introduction

This tutorial provides a step-by-step guide on how to preserve insect and other invertebrate specimens using ordinary hand sanitizer. This method is particularly useful for educational purposes, allowing you and the public to handle specimens safely. The use of clear plastic cuvettes enhances visibility and is ideal for examination under a microscope.

Step 1: Gather Your Materials

To get started, you will need the following items:

• Hand sanitizer (with a high alcohol content)
• Specimens (insects or other invertebrates)
• Clear plastic cuvettes or glass vials
• Tweezers (for handling specimens)
• Optional: superglue (for securing lids, if necessary)

Step 2: Prepare the Cuvettes or Vials

• If using cuvettes, ensure they are clean and free of any residue.
• If you are using glass vials, check for cracks or chips.
• For added security, you may apply a small amount of superglue to the lid of the cuvette or vial to prevent it from opening accidentally.

Step 3: Add Hand Sanitizer

• Fill the cuvette or vial with hand sanitizer until it is about three-quarters full. This allows enough space for the specimens to float without being crushed.

Step 4: Introduce the Specimens

• Using tweezers, gently place your specimens into the cuvette or vial.
• Ensure that the specimens are fully submerged in the hand sanitizer. This helps preserve their structure and color.

Step 5: Seal the Container

• If using cuvettes, securely close the lid to prevent leakage.
• If you opted for superglue, ensure it is dry before moving the container.

Step 6: Observe and Photograph

• Your specimens are now preserved and can be observed without the risk of damage.
• Consider taking high-resolution photographs for documentation or sharing. Use a suitable camera or smartphone to capture images through the clear container.

Conclusion

Preserving specimens with hand sanitizer is a simple and effective method that allows for safe handling and examination. By following these steps, you can create clear, visible samples suitable for educational purposes or personal collections. For further exploration, consider sharing your findings or images online to contribute to citizen science projects.
