Scope illumination might be a problem. That's a reflector at the bottom. Hard to get enough light with that at high magnification. I'm no expert though.

cheers,
i'll keep my eye on the auction for the hemocytometer and i'll do a bit mor research into the scope. maybe if i rig a bright light straight in front of the illuminator? or replace it with a halogen or similar? mmm i wonder.
most of the decent scopes are out of my budget over here, and freight costs kill the savings from shipping one in!

If it's worth doing, it's worth overdoing

You will definitely need a mechanical stage which I don't see on that scope.

So for those of you that have them or those of you who have experience with them, what qualities should one look for in a microscope? I mean, there are ones on amazon for about $35 which seems like a bad idea to me. And then there are the student recommended ones that are around $125.
I'm thinking of picking up the Yeast book, is this kind of stuff outlined in there? I would love to nerd out on yeast, I really enjoyed this stuff during highschool and actually thought I wanted to study biology in college until I realized how much harder it was and how much math and chemistry I would need.

OP -- would you consider doing a olive oil experiment with a few starters? I'd be curious to see how it effected actual yeast viability / counts.

You're going to have to spell it out for me -- I don't know what you're talking about. But yeah I'd be happy to do test something out for you. I'm a yeast factory in my den right now.

Recommended addition is 1mg olive oil per 25B cells. For a smack pack that's 4 mg of olive oil. How does one measure that? I'd probably go to 1 gram.
Doesn't olive oil float? Does it need to get boiled with the starter wort?

It did both, yeast viability and ester production. But yeah, it didn't really discuss growth - they were adding the olive oil during "storage".
