Re: snot, fly, ants along with equipment progress

Re: Perennial milk-weed - rust-fungus slides

Hi Tom, well for starters I'd suggest a 'soft' stem - leaves are far more difficult to start with. All I use for hand-sectioning is a single-sided razor-blade - a packet of 10 is dirt-cheap! Well the blades arrived today, so tomorrow I'll go find some stems and try my hand at sectioning. After I've...

So far I haven't found a really quick and effective process for cleaning of slides. Since I don't like to throw things away I will continue to look for one. I toss mine in a petri dish full of tap water, then every 4 days or so clean them with hand soap under a tap and dry with paper towel. A micro...

I would suggest that you try the Zeiss "trick": If you have a low-NA objective, say an 10x/0.25 for this scope, rotate the condenser turret to highest phase position and see if it creates DF. I'll try that next time I power up the scope but I've subsequently ordered a set of DF filter inserts that ...

Yes, I already have a container for slides and cover slips. I'm not too concerned though, it was a beginners dumb question.
