Fused Quartz Coverslip #No0

These are surprisingly sturdy for being only 0.10 mm thick. I've handled thinner glass before that cracked just from tweezers, but these quartz ones held up great while I was prepping my samples.

The 0.10 mm thickness is exactly what I needed for my confocal setup—no more light scatter issues. These quartz coverslips feel noticeably sturdier than standard glass ones, too.

The 0.10mm thickness is incredibly uniform across the whole piece, which made focusing much easier than with my old glass coverslips. Optical clarity is perfect for my work, no distortions at all.
