It's very easy to breed infusoria: you need to place a wisp of dried grass (hay) in the bowl of water and then put it in the warm place for a couple of days.
Customer service:
Thank you for your comment.

Julie Walker (2013.03.04)
Hello! That one can't regulate the thickness of the slice is a letdown. Do you have microtomes with micrometer-dial screws? Best regards.
Customer service:
Unfortunately this kind of microtomes is currently unavailable in our shop.

Julie Walker (2013.03.01)
Hello! Can you please explain to me how to use a microtome, I can't undestand what the book reads. How do I regulate the thickness of a slice?

You need to insert the sample in the sample holder and then cut the thin slice with rotary motion. The thickness is not adjustable.
