Today I am working with someone who is an algal bloom specialist. Deluded full strength seawater with Q water and stirred it with a stir bar on a magnetic machine that stirs it by itself. (see attached link below)
This was then put into an autoclave that uses steam to sterilize anything you put into it. The purpose of putting the natural seawater in there is to ensure a decontaminated media for algal culturing.
Now we are aseptically dispensing sterile media into culture flasks to prepare for inoculating fresh culture. This is all being done because it is time for the biweekly culture transfer.
This is a mechanical pipetter; the top button sucks up the media and the bottom one pushes it out and is connected to an external power source. These processes are more biological than chemical so the measurements are less precise.
