Flotation fluids: Eggs for culture

1. Saturated sugar solution

Specific gravity: 1.27

This solution should be used if the eggs are required for culturing as it has little effect on their viability.

Sugar (sucrose): 454 grams
Water: 355 ml

Add sugar to the water until saturated.

  • Stir solution well before using.
  • Saturation is indicated by the presence of sugar crystals at the bottom of the container after stirring for 15 minutes.
  • To prevent the growth of mould approximately 2ml of 37% formaldehyde can be added.
