APERA INSTRUMENTS / AI4685
Apera AI4685 is catalogued as a 1000 ppm potassium ion calibration solution in an 8 oz bottle. Keep the analyte, nominal concentration and catalog number together when specifying your calibration supplies.
A named calibration solution for the stated analyte.
Nominal catalog concentration; verify the label reporting basis.
Catalogued bottle size for AI4685.
An ion calibration solution and an ionic-strength adjustment buffer serve different roles. AI4685 is the potassium ion calibration solution, not a substitute label for a TISAB reagent. Use the exact analyte and concentration reporting basis called for by your electrode and calibration procedure.
Select this item when your instrument or electrode method specifies an appropriate potassium-ion calibration solution and the supplied concentration basis matches that method. Follow the method for working standards, sample conditioning and any required ionic-strength adjustment.
AI4685 is the Apera 1000 ppm potassium ion calibration solution in the catalogued 8 oz size. It is a solution-only item, not an electrode or meter kit.
It is identified as a potassium ion calibration solution. It is not a pH calibration buffer or a TISAB reagent.
Do not assume universal compatibility. Match the electrode manual, calibration method, concentration range and concentration reporting basis to the supplied solution label and documentation.
Not necessarily. The nominal catalog concentration is 1000 ppm. Any dilution, ionic-strength adjustment or preparation must follow your instrument and electrode method; no universal preparation recipe is specified here.
The exact label and lot documentation must establish the reporting basis. This page does not assign an unverified basis or conversion to the nominal 1000 ppm catalog value.
No. The catalogued order is one 8 oz potassium ion calibration solution. An electrode, meter, TISAB reagent and other standards are separate items unless expressly included in a different kit.
Match AI4685, the product name and bottle size against your order. Review the supplied label and documentation for concentration basis, lot identification, expiry and storage instructions before use. No particular certificate, shelf life or storage interval is promised on 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.
