22x22mm Cover Glass Slips

Good quality and packaged so they Dont get damaged

As expected

LOTS of cover slips

Standard microscope slide covers, used to make your sample lie down flatter in order to get a good view without having to constantly refocus to look at surface vs bottom details. Recommend.

They look good--as described. I like that they come in little boxes, though the box that holds all the little boxes is kind of flimsy.

You get a lot of cover glasses for the price.It will take me several years to go through them (I use them at home).This product is a tremendous value.

The coverslips were cheap, but unfortunately the glass surfaces are so dirty and filthy as to be unusable. They are probably OK for brightfield microscopy, but using phase contrast or differeential interference microscopy I can barely see the specimens through all the dirt. I tried cleaning the coverslips with windex and 95% isopropanol but what ever the dirt is - it doesn't come off easily. I usually use Zeiss 1.5H coverslips 0.17 mm thick which are excellent, but I had trouble getting them durng the pandemic. These coverslips are Ok for young kids, but for other uses I would avoid them. Other cheap coverslips I should mention are also often dirty.

There are a ton (1000) in this pack so the price is pretty decent. I did find that some of them were a bit dirty; I would expect these to be pristine but they're definitely not. Some isopropyl alcohol fixed that up pretty good.
