GLab Compound Student Microscope with LED LAMP,50 Blank N Two Prepared Slides ISO 9001:2015 Certified

If you want a cheap microscope that is good enough for lab use, buy this. This microscope is super crisp at 650x. Do not fall for microscopes claiming to have 2500x zoom. The best optical microscopes only go as high as 1500x. Anything higher becomes too blurry under optics. The wavelength of visible light isn't small enough to resolve anything at that kid of zoom levels. You need electron microscope for that.Even this microscope can do 1500x if you buy a 100x objective. You need that if you want to view the insides of cells. However, before you buy that, you need to know that this microscope may not be the best for it. The objective fits and works, but there is another issue. I will explain it. Before that, you need to know why even labs stick to 650x. The 100x objective required for 1500x zoom is too delicate for everyday use. Even dust can scratch it. Yet you must risk taking it within a millimeter of the slide to get a view. Also, it must be used with immersion oil, and oil attracts dust. That oil can also easily get into the other lenses when you rotate, damaging them.There are 100x objectives that do not require oil. But they cost over 20k and still can't show clear image over 850x. Just forget them.Now I will explain why this microscope is not best for 1500x. Its condenser part is entirely plastic. Before buying this, I did not know that the costliest part of a microscope is its condenser. Condenser isn't a big deal at 650x. But without a good condenser, even 1000x magnification will be too dark. A sturdy metal condenser alone can cost anything between ten and fifty thousand. The condensers in cheap microscopes like this are made out of toy-grade plastic and glue. They compensate for its lack of quality by providing a powerful LED light.The LED light in this is working and bright. But out of the box, it had a fitting issue. Inserted all the way in, it was going too far in to be at the condenser'S focus point. The LED bulb also gets tilted when you insert battery. Once again, none of this is an issue at 650x. But I want to go as high as 1000x. So I had to readjust the bulb. I also added a spacer to the mount rod. I will post the results once I receive the immersion oil.

The whole body is of iron and weight is around 2.5 kg. Can see the stoma through 100x and RBCs under 675 times. Overall performance is good but the illuminator is of cheap quality plastic. Got no slide broken all was fine.

Very good 👍

This microscope doesn’t show a clear image at all. All the slides look the same , only the color changes when switching slides. It’s not useful at all.

The microscop image quality was ok as there were some particals on the magnifing glass which were not able to remove .The slide quality was good . Its not value for money it should havw been cheaper . It not difficult to use. The functionality is ok as some of the parts were jammed

Exallent

The microscope is made up of iron.It is sturdy and strong. 2 prepared slides were given too.The quality of image is good too. Just a link of manual video or instruction book was must

Not happy. Both the eye pieces r defective. Ther r lots of spot/dirt on the lenses which can't be cleaned. 3k money waste for me
