Standard Practice for Preserving Zooplankton Samples — 2 стр.
Значение и использование

4.1 Calcium Carbonate (CaCO3) buffered formalin (3 to 5 %) can be used as a permanent preservative for zooplankton. Lugol's iodine solution can be used to preserve zooplankton for up to one year. Thirty percent ethanol, 30 % glutaraldehyde, or 25 % vinegar (can use 3 % acidic acid solution) can be used for more temporary storage and preservation of zooplankton samples. A 25 % vinegar solution is preferred to preserve soft-bodied planktonic coelenterates.
