MUHWA Microscope Glass Cover Pre-Cleaned 24mm x 50mm Coverslips 100 Pieces/Box

- These weren't compatible with my current project, but the *main* issue is that, as others noticed, they aren't what I'd call clean. I used to work as a bacteriologist in a medical lab, so I know what clean slides and cover slips look like. These, however, look AND feel as though they have almost a film on them, like they were dunked in a solution that wasn't very clean and clung to the glass.- It's not so obvious that it jumps out at you when you take one out of the box, but the film is seem when they're held at an angle to the light.-- Even if I could have been able to shape them enough to use them in my project(s), I'd have to figure out how to clean them, and then clean each one before using it.- If, however, I was still doing any work with a microscope, they'd drive me totally bonkers.-- As fragile as they are, I don't even know how I'd be able *to* clean them, since I had found a few that were broken in the box.

Not precleaned

Very thin easy break....

Arrived on time, an excellent package and all slides intact. Excellent price point too.

First they came within a week which is good. They work I purchased them before which is why I purchased 3 more boxes. They can be cleaned and reused as well though about 40% do break while cleaning. The large size are good for blood smears, or assessing plankton and aquatic microogranisms.

Can't get it on an image due to reflection, but these slides are far from clean. I've checked multiple ones both from the center and outsides of the package. All of them have mineral deposits on them and all of them have dust on them. It's almost like they were washed using tap water and dried in the open air.
