Fused Quartz Coverslip #No5

The edges are cleanly cut and the 0.50mm thickness sits perfectly flat under my microscope objective. Arrived in one piece, no chips or scratches, which is more than I can say for cheaper coverslips I've tried.

The 0.50mm thickness is exactly what I needed for my fluorescence work — no more cracked edges like the cheaper slips I used before. Clarity is excellent and they arrived well packed, zero chips.

I was worried about finding a coverslip that wouldn't distort my UV fluorescence imaging, but this fused quartz piece is perfectly clear and the 0.5mm thickness feels sturdy without being bulky.
