Hanna Instruments Replacement Glass Cuvettes for HI95 / HI96 / HI97 Series Photometers (Pack of 4) (HI731331)

Hanna Instruments Replacement Glass Cuvettes for HI95 / HI96 / HI97 Series Photometers (Pack of 4)

The HI731331 is a pack of four optically clear replacement glass cuvettes designed for use with Hanna Instruments HI95, HI96, and HI97 series portable photometers and turbidity meters. Each 10 ml cuvette features a clearly marked fill level line and an index mark for correct alignment, ensuring consistent and accurate optical measurements every time. Caps are not included and must be ordered separately.

Compatibility

These cuvettes are the standard sample vessels supplied with the HI96 series portable photometers and are equally compatible with HI95 and HI97 series instruments. If you need replacement caps, order HI731335 for HI95/HI96 series devices or HI731336N for the HI97 series. The 10 ml volume and 22 mm diameter make them the correct fit for the optical measurement cell across all three series.

Why genuine matters

Accurate photometric and turbidity measurements depend entirely on the quality of the cuvette in the optical path. Even minor scratches, discolouration, or residue on the glass will interfere with light transmission and compromise your pool water test results. Genuine Hanna Instruments glass cuvettes are manufactured to the optical tolerances required by the instrument’s narrow-band interference filter system, protecting measurement integrity and keeping your readings trustworthy.

Installation & use

Fill each cuvette to the 10 ml mark, then insert it using the index mark to align it correctly in the photometer’s measurement cell. The positive-locking system built into HI95/96/97 series meters ensures the cuvette seats in the same position every measurement cycle. Replace cuvettes as soon as any scratching or discolouration is visible to maintain measurement accuracy. Caps (sold separately) are recommended when storing prepared samples.
