Standard Glass Cuvette Cell Spectrophotometer cuvettes 10mm pathlegnth, 3.5ml; (Set of 4pcs) Spectrometer Cell 2 Clear Windows

Just what I needed for testing. Well made cuvettes with super-clear walls. Thin enough glass but also sturdy enough to hold up to the occasional laboratory slip. Worked perfectly for my use case and will be getting more once I fatally drop these on my tile floor (not the fault of the product - all on me). But I'm glad I know which brand to buy now. Very happy with the LAB4US Standard Glass Cuvette and happy they're affordable once my clumsiness wins the battle against fragile glass.

Husband was captivated by the shape of these cuvettes, and has found them to be very helpful with some kind of chemical experiments I probably don't want to know about. He says they are well made and are working well for him.
