Keep your aluminum method supplied.
Replenish an established aluminum-testing setup with coordinated A, B and C powder reagents. Hanna HI93712-01 supports 100 tests and HI93712-03 supports 300 tests. Both packs supply the same Aluminon chemistry for sample analysis; neither is a photometer or a set of instrument-check standards.

Fit for the HI97712 method
The HI97712 aluminum photometer uses these reagents over 0.00 to 1.00 mg/L as Al³⁺. Its manual directly names both refill packs and their three required components. The 300-test option extends your reagent supply, not the measurement range. Compatibility and range here refer specifically to the verified HI97712 procedure, not every Hanna benchtop method.
What the refill supplies
Select one complete 100- or 300-test pack. Each determination consumes one packet each of HI93712A-0 Aluminum Reagent A, HI93712B-0 Aluminum Reagent B and HI93712C-0 Aluminum Reagent C. Test capacity counts complete determinations, not the number of individual sachets. Order quantity 1 for one selected sellable pack.
How the chemistry works
The Aluminon adaptation develops a reddish tint in the presence of aluminum. A and B are dissolved into the initial sample preparation; C is used only in the blank cuvette. This two-cuvette approach is part of the method, so the untreated sample alone is not the specified blank.
Choose a pack for your testing schedule
Choose the smaller pack for occasional analysis or the larger pack for a regular schedule. Allow for repeats and quality-control determinations, and plan consumption around the supplied lot’s expiration date. All three components are required for a complete test; extra capacity does not remove the blank or the development time.
Prepare the equipment separately
Have the HI97712 photometer, graduated beaker and two appropriate clean cuvettes with caps and stoppers available separately. Keep blank and sample cuvettes identified, use the same optical alignment for readings and keep the outside surfaces clean. CAL Check standards verify instrument response; they do not replace A/B/C sample reagents.
Follow the measurement sequence
Start with 50 mL of sample in a graduated beaker. Dissolve one A packet, then one B packet. Fill two cuvettes with 10 mL each of this prepared sample. Add one C packet to cuvette 1 only, cap and dissolve it to make the blank. Zero with that blank after the 15-minute development period, then read cuvette 2. Use the complete HI97712 manual or tutorial for the full sequence.
Check the sample matrix
The HI97712 manual identifies interference from alkalinity above 1000 mg/L, phosphate above 50 mg/L and iron above 20 mg/L. Fluoride must be absent for the uncorrected result; the manual provides a correction graph when fluoride concentration is known. Review those limits before selecting this method for a sample matrix. This listing does not establish a total-aluminum digestion or universal seawater method.
Shipping and safe handling
The manufacturer identifies both pack sizes as Dangerous Goods, restricted to ground shipment. Review every component-specific US SDS and the supplied labeling before handling, storage or disposal. Manufacturer website availability is not a verified dispatch date or a promise of physical stock.
Frequently Asked Questions
Which pack should I select?
Choose HI93712-01 for 100 complete tests or HI93712-03 for 300 complete tests. Both provide the same A/B/C aluminum chemistry. The larger pack changes capacity only, not range or procedure.
What does HI97712 report?
The primary range is 0.00 to 1.00 mg/L as Al³⁺. The instrument also offers an aluminum oxide Al₂O₃ display conversion. Record the selected chemical form rather than treating these two reporting bases as identical.
Which components are used per determination?
Use one packet each of HI93712A-0 Aluminum Reagent A, HI93712B-0 Aluminum Reagent B and HI93712C-0 Aluminum Reagent C. A and B go into the 50 mL preparation; C goes into the blank cuvette only.
Why do I need two cuvettes?
After dissolving A and B in the sample, transfer 10 mL to each cuvette. Cuvette 1 receives C and becomes the blank. Zero on that blank after the specified development period, then read cuvette 2. Do not add C to both.
How long does the aluminum method develop?
The HI97712 procedure uses a 15-minute countdown before zeroing the prepared blank. Follow the meter tutorial or complete method for timing and handling; do not take an immediate reading just because the powders appear dissolved.
Can fluoride or other ions affect results?
The HI97712 manual identifies interference from alkalinity above 1000 mg/L, phosphate above 50 mg/L and iron above 20 mg/L. Fluoride must be absent for the uncorrected result; the manual provides a correction graph when fluoride concentration is known. Review those limits before selecting this method for a sample matrix. This listing does not establish a total-aluminum digestion or universal seawater method.
Does this pack include the meter or CAL Check standards?
Have the HI97712 photometer, graduated beaker and two appropriate clean cuvettes with caps and stoppers available separately. Keep blank and sample cuvettes identified, use the same optical alignment for readings and keep the outside surfaces clean. CAL Check standards verify instrument response; they do not replace A/B/C sample reagents.
How should I handle and store the refill?
Review the three linked component-specific US Safety Data Sheets before use and disposal. Follow the supplied labeling for storage and expiration. The manufacturer identifies these packs as Dangerous Goods restricted to ground shipment; this is not a promise of stock availability or dispatch time.
