Hanna Instruments HI731360 Glass Cuvette with Cap (2 Pieces)

The Hanna HI731360 Glass Cuvette with Cap is a set of two replacement glass sample cuvettes, each with its own cap, for Hanna HI977 series portable photometers and the Marine Master. The optically clear glass lets light pass cleanly through your sample so your meter reads accurately. Keep a spare set on hand and swap them in when your originals get scratched or stained.

FAQ

Which meters does this fit? The Hanna HI977 series portable photometers and the Marine Master. Check your instrument model before ordering.

Will it work with my Hanna Checker? No. The handheld Checker HC colorimeters use the smaller HI731315 cuvette. This HI731360 is for the larger photometers.

How many do I get? Two glass cuvettes and two caps.

Why would I replace a cuvette that still works? Even light scratches or film scatter the light your meter reads, which quietly skews results. Fresh, clear glass keeps your tests trustworthy.
