APERA INSTRUMENTS / AI4609
Apera AI4609 is catalogued as Total Ionic Strength Adjustment Buffer A for calcium ion electrodes, in an 8 oz bottle. Specify the exact buffer letter alongside the catalog number when replenishing your method supplies.
The buffer letter is part of the product identity.
For the catalogued calcium electrode application.
Catalogued bottle size for AI4609.
A calibration standard supplies a stated nominal analyte concentration. An ionic-strength adjustment buffer is a separate method reagent. TISAB A is the adjustment buffer identified for the electrode application above; do not treat it as a 1000 ppm calibration standard or interchange it with another TISAB letter based on bottle appearance.
Use AI4609 when your exact electrode and method specify a suitable TISAB A reagent. Follow that method for which solutions receive buffer, preparation order, additions and calibration. The catalog name alone does not establish an addition ratio, pH, preservative or compatibility with every electrode.
AI4609 is the catalogued 8 oz TISAB A Total Ionic Strength Adjustment Buffer for calcium ion electrodes. It is a solution-only reagent.
No. This item is catalogued as an ionic-strength adjustment buffer, not as a standard with a stated analyte concentration. Use separate standards where required by your method.
The catalog identifies calcium ion electrodes. That application statement is not a universal compatibility guarantee for every electrode; check the exact electrode and method requirements.
Follow the exact electrode and method instructions. No universal buffer-to-sample ratio, dilution recipe or preparation order has been verified for publication here.
Do not assume the letters are interchangeable. Match the buffer type, target analyte and method requirements. A shared bottle size or manufacturer does not establish equivalent formulation.
One catalogued 8 oz TISAB A solution bottle under AI4609. A meter, electrode, calibration standards and other reagents are separate unless expressly included in a different kit.
Use the actual supplied label and safety documentation for storage, handling and expiry. No particular temperature interval or shelf life is promised by this page.
No. The bottle graphic is an AI-generated product-identification illustration using the catalogued name, SKU and size, and nominal concentration where specified. It is not manufacturer photography or a reproduction of the supplied label. Actual packaging and label layout may differ; use the supplied product documentation for analytical and safety information.
