Good question. For the most part, since you are only using a single drop of stain like iodine, it’s ok to put it down the drain and wash the slides with soap and water. For experiments involving more volume, like with chemistry, we go over how to dispose of things properly at the end of each video.
When working with slides and chemicals. What is the best way to clean and dry them when done? Thank you
Yes, that looks comparable to the ones I recommend. You want one with a mechanical stage, which it has. The iris is nice, and most scopes now have fluorescent bulbs. I would ask what their return policy is before purchasing just in case. It’s in the “decent scopes” price range (don’t buy anything under $100), so you probably will be okay.
http://www.sonlight.com/microscope.html Aurora, Any thoughts on this one?
I totally understand this concern! Most of these make better doorstops than scientific equipment. I personally reviewed several and here are my recommendations for microscopes. If you want to know the one I personally use, it’s this one from GreatScopes.com.
Where is the best place to get a compound microscope that kids can use? I’ve bought a couple but they are always so cheap the kids can’t see anything in them.
