United Scientific™ Microscope Slides, Pre-Cleaned Glass 3"x1", 72 Pack

These pre-cleaned microscope slides are excellent quality and have saved me a ton of prep time. I use them for examining various materials - from checking the layer adhesion on my 3D prints under magnification to inspecting vintage collectibles for authenticity markers. The slides arrive truly clean with no residue or contaminants, which means I can use them right out of the box. The glass quality is consistent with good optical clarity and no distortions. They're properly sized at 3x1 inches, which is standard for most microscopes. The edges are ground smooth so there's no risk of cuts when handling them. At 72 slides per pack, it's a great value - I don't have to worry about running out or rationing them. The packaging keeps them protected during shipping with no chips or breaks. Whether you're doing hobby microscopy, quality control work, or educational projects, these slides perform exactly as expected. Highly recommend for anyone needing reliable slides without the hassle of cleaning.

These come in a lil box with a lid that comes off really easily. I recommend putting it in a ziploc bag or something if you'll be keeping them in a backpack so your slides don't go everywhere! They weren't flimsy and pretty easy to use for my needs, they got the job done. Worked well for gram staining, catalase tests, and viewing specimens under a microscope! The catalase test is the only one I got a picture of the slides with unfortunately 😫 But the gram stains and all that other fun jazz work just fine on these as well! :)

I’m really happy with this purchase. The microscope slides arrived perfectly clean, just as advertised, no dust, smudges, or fingerprints. It’s so frustrating when new slides come dirty from other brands, but these were ready to use right out of the box. The quality of the glass is good, and they work well for my biology lab needs. If you need reliable, clean slides for experiments or classroom use, I definitely recommend these.

The slides arrived in perfect condition and were securely packaged. The glass is perfect for lab practice. The box contains 72 slides, which is a great value for the price. Very satisfied with this purchase, I would definitely order again.

Smaller than expected but overall good product.

Ordered these because they were needed for my college microbiology course, the slides work perfectly, and there are plenty in this set! I have used them for gram stains under the microscope and haven’t had any issues, of courses they aren’t the upmost quality but they do exactly what is necessary for my class.

This basic plate is evenly cut with precision, perfect for my project. Be careful handling sharp glass edge still. I am glad I found this economic package as I may use many a day, labeling it with marker. I use Scott tape instead of small cover plates, making it very affordable and easy to handle. The plates are about 1 mm think that makes them strong and hard to break.

Came dirty. I imagine they were cleaned at some point, but there was dust and residue that came in the packaging, compromising the slides. Okay value for money, just expect that they may come dirty.
