Made for the HI7XX Checker HC family

Hanna identifies HI731315 for HI7XX Checker HC colorimeters. Selected supported setups include HI713, HI717, HI753 and HI782; HI782 explicitly lists HI731315 in its accessory instructions. Match the set to your existing Checker setup and follow the procedure for the exact model.

What is—and is not—in the pack

This set includes its two plastic caps, unlike the four-piece HI731331 glass-only pack. It does not include a Checker, reagents or CAL Check standards. Do not transfer the larger cuvette dimensions or the HI731335N/HI731336N cap choices to this Checker set.

When a refill makes sense

Keep a clean spare set available when cuvettes go missing or glass becomes scratched or discolored. Hanna also describes using extra cuvettes for more samples and averaging results. Keep each test’s timing and sample-handling steps consistent with the Checker method; extra glass does not change the measurement range.

A clean-cuvette workflow

Inspect the cuvettes for scratches or discoloration before testing. Prepare and fill each sample according to your Checker method, using the 10 mL mark where the method calls for it. Secure the supplied cap as directed, remove exterior moisture and fingerprints, and follow the model’s zeroing, reagent and timing steps. Clean and store the cuvettes according to the instrument instructions.

Frequently Asked Questions

Does set of 2 mean two cuvettes and two caps?

Yes. One HI731315 set contains two glass cuvettes and two plastic caps. Order quantity 1 for that complete set, not for a single cuvette.

Which Checker family is this set intended for?

Hanna identifies HI731315 for HI7XX Checker HC colorimeters. Selected supported setups include HI713, HI717, HI753 and HI782. Match the accessory to your existing instrument setup and use the instructions for the exact Checker model.

Is HI731315 named in the HI782 instructions?

Yes. The HI782 accessory instructions explicitly list HI731315 as the glass cuvette and cap set for Checker HC colorimeters. HI713, HI717 and HI753 are supported here by official family/accessory-page information, not an assertion that every current manual names this exact set code.

Is this interchangeable with HI731331?

Do not substitute by appearance. HI731315 is the Checker HC set with two cuvettes and two caps. HI731331 is a separate four-piece glass-only cuvette pack for other supported photometer/turbidity setups. Match your accessory code before ordering.

Are reagents or CAL Check standards included?

No. This is empty replacement glassware with plastic caps. The Checker instrument, test reagents and CAL Check standards are separate products; sample cuvettes are not calibration standards.

When should I replace a cuvette?

Replace scratched or discolored glass, which can interfere with an optical measurement. A spare set is also useful when original cuvettes are lost or you need additional clean cuvettes for more samples.

Does the 10 mL mark determine every test procedure?

No. It provides a visible fill reference. Follow your exact Checker method for sample volume, zeroing, reagent addition, mixing and reaction time. Additional cuvettes do not change the method’s range or timing.

How should I care for the cuvettes between tests?

Follow the instrument’s cleaning and storage instructions. Inspect the optical surfaces, keep the exterior clean and dry for readings, and avoid using scratched or discolored glass. Use the supplied plastic caps as directed for the matched Checker setup.
