Crayfish 3 - 4" PLAIN - NO DYE

*Note - quantity greater than 1 will be bulk packaged.

  • This non-toxic solution and specimen can be discarded with regular trash.

Our preserved specimens are prepared in the United States.

The specimens are originally preserved in formaldehyde, then rinsed and stored in Nebanol. (Non-toxic solution)
This is a non-toxic storage solution. It is safe to dispose of the specimens in your normal household/business trash disposal.
You may prefer to use disposable gloves during the experiment.

1. Fluid in the bag is normal and OK.

2. Store at room temperature in the original sealed bag for 6- 9 months.

3. Do not store with food items!

4. Do not add water to the specimen bag, it will cloud the solution and allow bacteria growth.

5. You can use 70% Isopropyl alcohol if you need a rewetting solution or short term storage solution.

6. Avoid touching the eyes and mouth during the lab.

7. Open the bag when you are prepared to complete the dissection.

8. If your dissection will take several days, we recommend covering and sealing the specimen with plastic wrap or a plastic zip-top bag between sessions to preserve the moisture. (Use 70% Isopropyl Alcohol if needed to prevent drying out)

9. After the dissection, dispose of the specimen, fluid and any disposable items in your normal trash disposal.

10. Disinfect the work station with hot soapy water or disinfectant spray.
