Introduction: Will It Centrifuge? (part 2 - Blood!)
Only a slide-show again, because I was just taking an opportunity that came up.
A colleague at school did a lamb's-heart dissection, so I grabbed a few millilitres of the blood and centrifuged it at 8,500g for five minutes.
I did not get the results I expected (see the slideshow). I was blaming it on the blood being at least two days old before I got to it, and not kept cool enough in that time, but I have since found out that blood is usually centrifuged for at least half an hour.
