I want to know about the approximate density of microalgae powder
Weigh a few mgs and suspend in about 10 mL of growth medium>Use a haemocytometer to assess cell/mL. WE have used an ultrasonic cleaning bath to get rid of clumps. Such a piece of relatively cheap hardware should be available in any lab dealing with microalgal counting.
Weigh an empty eppendorf, fill it with powder up to the 1 mL graduation and weigh it again. The mass of powder that you'll find (expressed in grams) will correspond to the density you're looking for.
yes Claire, since the definition of density is mass per unit volume. I have been trying to convince my students and fellow workers that cell concentration is a commpletely different concept. Thank you
It depends on how many grams you add to however much water or media you choose. If you add 1 gram of powder to 1 liter of water the density would be 1g/L .
