APERA INSTRUMENTS / AI1109
Apera’s AI1109 kit refills a full three-point pH calibration: 8 oz bottles of pH 4.00, 7.00 and 10.01 buffer, plus a 4 oz bottle of 3M KCl storage solution for pH and ORP electrodes. It has no organizer.
The pH buffers are standardized against NIST certified pH references to within 0.01 pH at 25°C (77°F), color-coded and rated for a two-year shelf life. Bottle labels carry temperature reference charts.
Pick two or three pH points, 8 oz or 16 oz bottles, and whether you also need conductivity standards. Each card opens that kit.

Contents follow Apera’s AI1109 listing.
Calibrate at pH 7.00 first, then pH 4.00 and pH 10.01. Pour each buffer into its own cup, rinse the electrode with distilled or deionized water between points, and never pour used buffer back into the bottle.
Keep pH and ORP electrodes in the 3M KCl solution between uses. Never store them in distilled or deionized water.
Buy single bottles to top up: pH 4.00 Buffer, pH 7.00 Buffer, pH 10.01 Buffer, 3M KCl Storage Solution.
pH 4.00 buffer, 8 oz; pH 7.00 buffer, 8 oz; pH 10.01 buffer, 8 oz; 3M KCl storage solution, 4 oz.
±0.01 pH at 25°C (77°F), standardized against NIST certified pH references.
Two years for the pH buffers. Expiration dates are printed on each bottle.
Yes. The solutions calibrate any brand of pH meter, tester or controller.
No. Add the CalPod organizer (AI2910) separately, or choose a kit with one, such as AI1114 or AI1116.
Check the catalog number (AI1109) against your meter, electrode and calibration routine, then return to the live price and ordering controls.
Shelf life: 2 years for pH buffers. Expiration dates printed on each bottle.
Store at room temperature, away from direct sunlight, with caps tightly closed.
Apera prints the expiration date and a temperature reference chart on each bottle. Safety data sheets and a certificate of analysis are available from Apera on request; contact Blue Tiger Scientific with your order number and lot.
