Ready-to-use powder for your HI713 phosphate workflow

HI713-25 replenishes the HI713 Phosphate Low Range Checker HC with enough reagent for 25 tests. It is the powder-reagent choice for the low range method—not the liquid-and-powder reagent set used by the HI717 high range Checker. Match the reagent code to the HI713 before ordering.

Pre-measured packets simplify sample preparation without weighing out individual doses. Hanna prepares the reagents with high-purity chemicals and prints the lot number and expiration date on each packet to support traceable routine testing.

Matched chemistry for a defined measurement range

An adaptation of the Ascorbic Acid Method in Standard Methods for the Examination of Water and Wastewater, 20th Edition, produces a blue tint when phosphate reacts with the reagent. The HI713 measures that color and displays phosphate concentration in ppm, equivalent to mg/L, across its 0.00 to 2.50 ppm range.

A straightforward HI713 sample workflow

Zero the HI713 with 10 mL of unreacted sample in a clean cuvette. Add the contents of one HI713-0 powder packet, replace the cap and shake gently for two minutes until completely dissolved. Then use the three-minute countdown before measurement. Consult the downloadable HI713 manual for the complete operating sequence.

Keep the cuvette exterior clean and dry, avoid bubbles and respect the specified reaction timing. Review the linked Safety Data Sheets before handling and arrange appropriate disposal of reagents and reacted samples. Hanna restricts products classified as dangerous goods to ground shipping; confirm shipping eligibility before selecting an expedited service.

Order the right reagent pack

One HI713-25 pack contains reagent for 25 low range phosphate tests. No liquid reagent is required by this method. The HI713 Checker, cuvettes and HI713-11 calibration-check standards are separate products. Plan use against the expiration date printed on the packets; this pack does not extend the measuring range of the instrument.

Frequently Asked Questions

Which Checker uses HI713-25?

This reagent pack is verified for the HI713 Phosphate Low Range Checker HC. Do not substitute it for HI717-25 high range reagents or assume compatibility with a different Checker model.

How many tests are in one HI713-25 pack?

Hanna specifies enough reagent for 25 phosphate low range tests. The HI713 method uses one pre-measured powder packet per test.

What phosphate range can I measure?

On the HI713, the method covers 0.00 to 2.50 ppm as phosphate, equivalent to mg/L. This is not the HI717 high range method.

Does this method need liquid reagent?

No. The HI713 procedure adds one HI713-0 powder packet to 10 mL of sample. The HI717 liquid-and-powder method uses a different reagent set.

What mixing and reaction times should I follow?

The HI713 manual instructs gentle shaking for two minutes until powder dissolves, followed by a three-minute countdown before reading. Follow its complete zeroing and measurement sequence.

Are the instrument and cuvettes included?

No. This listing supplies replacement reagents only. The compatible instrument, cuvettes, caps and calibration-check standards are separate products.

How can I check reagent traceability?

Read the lot number and expiration date on the supplied reagent packaging. Manufacturer photographs are illustrative; their printed dates do not identify the lot or expiration date you will receive.

What should I do before handling the reagents?

Read the linked Safety Data Sheets and the exact instrument procedure before testing. Use appropriate protection, keep cuvettes clean and dry outside, avoid bubbles and arrange suitable disposal of reagents and reacted samples.
