United Scientific™ CSTK02 Concavity Glass Slide, 3mm Thick, 2 Concavities, 75mm Length, 25mm Width, Pack of 12

Good quality and individually wrapped. Beware of the 3mm thickness, "about twice the thickness of regular", won't fit standard storage box.

Great quality and clarity. The double well is extremely handy for the microscopy work. Even has beveled edges.

These are really thick! Several of them were not entirely clean, right out of the package.

Purchased this with the microscope and a hemocytometer early in the lockdown homeschooling days. It allowed me to do backyard science experiments with the seven year old. Was perfect for the "Hay Infusion" experiment. Highly recommend.

AWFUL. They're thick, which can be desirable, but they look like they were ground by an eight year old using a belt sander. I mean, could you at least grind them smooth so there aren't grooves obscuring the subject?

Nice thick slides with a decent depth and smoothly polished cavity.

Wow! These are quality slides. They are thick glass individually wrapped in plastic. These will make our impromptu science observations so much easier than having to wait for nail polish to dry. Thank you!

Good value.

I love these. Just make sure you know how to use it: You need to put enough drops of your specimen so that the water tension pulls the water completely over the coverslip when you place it, otherwise you will have air bubbles under the coverslip. The slide is quite thick, but this doesn't matter, the important thing is that your coverslips are the right thickness for your microscope objectives (usually 1.5 is the standard, but take special note for your objectives.)

great product. The sellers were very helpful when my product was lost by UPS.

Buen material de calidad lo recomiendo
