It is offered in 1-pint and 1-gallon sizes, so labs can match the volume to how often they calibrate.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhy calibrate at pH 10.\u003c\/strong\u003e Most pH meters calibrate with two or three buffers. pH 7 sets the zero point, and a second buffer sets the electrode slope. When samples are alkaline, pairing pH 7 with pH 10 brackets the measurement range, so readings between 7 and 10 are interpolated rather than extrapolated, which improves accuracy.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHow a buffer holds its pH.\u003c\/strong\u003e A buffer contains a weak acid and its conjugate base, or a weak base and its conjugate acid, in balanced amounts. When small amounts of acid or base enter the solution, one partner neutralizes them, so the pH barely moves. That resistance to change is what makes a buffer a reliable reference point for calibration, unlike plain water.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhy color-coded blue.\u003c\/strong\u003e Blue is the widely used color for pH 10 buffers, alongside red for pH 4 and yellow for pH 7. Color coding lets technicians identify the right buffer at a glance, reduces mix-ups during multi-point calibration, and makes it easier to spot a buffer poured into the wrong container.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensitive to carbon dioxide.\u003c\/strong\u003e Alkaline buffers absorb carbon dioxide from the air, which forms carbonic acid and gradually lowers the pH. That is why manufacturers recommend using an opened pH 10 buffer sooner than pH 4 or pH 7. Keep the container closed, pour out only what you need, and discard used buffer rather than returning it to stock.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature matters.\u003c\/strong\u003e A buffer's pH changes slightly with temperature, so the value printed on the label applies at 25 °C. For best accuracy, calibrate at the same temperature as your samples, use a meter with automatic temperature compensation, and apply the temperature-correction values supplied with the buffer when they are provided.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo sizes for different workloads.\u003c\/strong\u003e The 1 pint size (ZB1634-16EA) suits benches that calibrate a few times a week, and its smaller volume is used up before carbon dioxide uptake becomes a concern. The 1 gallon size (ZB1634-128) suits QC and production labs that calibrate several meters daily.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCalibration best practice.\u003c\/strong\u003e Rinse the electrode with deionized water, blot it gently between buffers, immerse it in a fresh buffer in a clean beaker, stir gently, and wait for a stable reading before accepting each point. Calibrate before each day's measurements, or more often as the method requires, and record the meter-reported slope to track electrode health.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhere it is used.\u003c\/strong\u003e Use pH 10 buffer to calibrate benchtop, portable, and in-line pH meters in water and wastewater treatment, environmental testing, food and beverage QC, chemical manufacturing, education, and any process where samples run alkaline. It pairs with Lab Pro's Buffer Solution pH 7, Yellow, and Buffer Solution pH 4, Red for full three-point calibration.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003ctable style=\"width:100%; border-collapse:collapse; border:1px solid #cfcfcf; margin-bottom:28px;\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #cfcfcf; padding:8px 12px; vertical-align:top; text-align:left; width:32%; background:#f5f5f5;\"\u003e\u003cstrong\u003eProduct\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #cfcfcf; padding:8px 12px; vertical-align:top; text-align:left;\"\u003e\u003cstrong\u003epH 10 buffer solution, color-coded blue\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #cfcfcf; padding:8px 12px; vertical-align:top; text-align:left; width:32%; background:#f5f5f5;\"\u003e\u003cstrong\u003eNominal pH\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #cfcfcf; padding:8px 12px; vertical-align:top; text-align:left;\"\u003e\u003cstrong\u003e10 at 25 °C\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #cfcfcf; padding:8px 12px; vertical-align:top; text-align:left; width:32%; background:#f5f5f5;\"\u003e\u003cstrong\u003eColor Code\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #cfcfcf; padding:8px 12px; vertical-align:top; text-align:left;\"\u003e\u003cstrong\u003eBlue\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #cfcfcf; padding:8px 12px; vertical-align:top; text-align:left; width:32%; background:#f5f5f5;\"\u003e\u003cstrong\u003eUse\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #cfcfcf; padding:8px 12px; vertical-align:top; text-align:left;\"\u003e\u003cstrong\u003epH meter and electrode calibration, slope verification\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #cfcfcf; padding:8px 12px; vertical-align:top; text-align:left; width:32%; background:#f5f5f5;\"\u003e\u003cstrong\u003ePackage Sizes\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #cfcfcf; padding:8px 12px; vertical-align:top; text-align:left;\"\u003e\u003cstrong\u003e1 pint; 1 gallon\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch4\u003eAvailable Variants\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eZB1634-16EA (BB2070-500):\u003c\/strong\u003e 1 pint, sold individually, for occasional calibration.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eZB1634-128:\u003c\/strong\u003e 1 gallon for labs that calibrate several meters daily.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eApplications \/ Common Uses\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003epH meter calibration:\u003c\/strong\u003e Serves as the alkaline calibration point alongside pH 7.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSlope verification:\u003c\/strong\u003e Checks electrode response after calibration or cleaning.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDaily QC checks:\u003c\/strong\u003e Confirms meter accuracy before a run of alkaline samples.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater and wastewater testing:\u003c\/strong\u003e Brackets alkaline samples in treatment and compliance testing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTeaching labs:\u003c\/strong\u003e Demonstrates buffer behavior and meter calibration.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStorage, Handling \u0026amp; Shipping\u003c\/h4\u003e\n\u003cp\u003eStore pH 10 buffer tightly closed at room temperature, protected from light and freezing.
