Review on 🔬 Karter Scientific Standard Microscope - 22x22mm Lens Size by Edward Perez
Thickness not promised (surprise surprise).
Once again I was tricked into buying something other than what was promised. measured from 0.196 to 0.202 mm with a calibrated probe with a resolution of 2 microns. For some reason this seems to be normal practice for many vendors these days, despite the near-universal standard of 0.17mm. I'm picky, but if a supplier claims a .13 to .16 thickness range, state it or print an honest size on packaging and in marketing literature. Also, there is no batch number or expiration date. The date is printed on the packaging - the fields are completely empty. This is another sign of poor quality control.
- Pack of 200 pre-cleaned 22mm x 22mm rectangular coverslips
- Could have chosen a newer model
