ELECTRIC IMPEDANCE OF HIPPONOË EGGS [PDF]

open access: yesJournal of General Physiology, 1935
Alternating current resistance and capacity measurements have been made from 1.08 103 to 2.32 106 cycles per second on suspensions of unfertilized, fertilized, and swollen unfertilized eggs of the echinoderm Hipponoë esculenta. A simple method has been developed for measuring the volume concentration of eggs in a suspension.
