To do

  • Desiccate rotifers for
  • re-extract failed rotifers

Rotifer dessication

  • prepare rotifers
    • take three vials of each species to be tested
      • one as a test rehydration, one to take to Japan, one to keep in the Mark Welch lab
    • Add small pieces of filter paper to the rotifer culture, and remove most water with a pipette, leaving .3-.5 ml
    • note number of rotifers
  • prepare humidity chamber
    • The dry salt is spread about 3 mm deep in a petri dish that occupies most of the bottom of a small airtight bottle.
    • Water is added to moisten the salt -- do not add more water than is needed to make the salt look damp.
    • keep each salt for about 4 hours, then replace with the one giving a lower relative humidity.
    • keep under Potassium carbonate until dry (also for long-term storage @ rt)
    • once dry, put both vials at -80C
  • Relative humidity table
Salt RH (%)
Potassium carbonate 43.2
Sodium chloride 75.3
Potassium chloride 84.3
  • We can also use Sodium bromide (RH 57.6%) as an intermediate, if necessary
