Buffer pH 4,7,10 and pH probe storage solution Kit

$18.95

Buffer solution lets you calibrate any pH tester to ensure accuracy. Choose from pH 4, 7, or 10, now available with the pH probe storage solution kit.

Helps you achieve the accuracy that is critical for measuring pH in wastewater, storm water, and process liquids.
Makes calibration easy — just adjust your tester to the pH value of the solution in a clean container.
Available in pH 4, pH 7, and pH 10 buffer solutions with a pH probe storage solution kit.
If unopened, shelf life is 2 years. Once opened, use pH 4 and pH 7 within 90 days and pH 10 within 30 days.

The pH probe might dry out when it has not been used for a long time, leading to wrong or false pH measurement results. Your probe may require reconditioning. Dawn Sci’s pH probe conditioning kit contains the necessary solution to bring your probe back to normal working condition. Please try our pH probe reconditioning solution before discarding your expensive probes. Our reconditioning kit may give new life to your probe and save you a lot of money.

All you have to do is dip the pH probe in this three-step reconditioning chemical bath, and your probe could be as good as new. The entire process takes about 5 minutes.

It may give new life to your expensive probe.
5-minute process to check.

Instructions:

Step-01: Place your probe in Solution-1 for 15 seconds and then rinse with water.

Step-02: Place your probe in Solution-2 for 15 seconds and then rinse with water. Repeat Steps 1 and 2 three more times, and then check the performance of your pH probe. If your pH probe needs further conditioning, proceed to Step 3.

Step-03: Place your pH probe in Solution-3 and wait 3 minutes, then rinse with water.

Cautions: Please wear appropriate PPE as this reconditioning kit contains acids and bases.

In contrast to reference pH calibration solutions, the composition of technical buffer pH solutions is not regulated. Therefore, the temperature reaction of these calibration solutions can vary, even if they have the same nominal pH value at 25°C. At calibration temperatures other than 25°C, considerable errors may occur in the pH results. Additionally, the calibration procedure significantly affects measurement accuracy. The following pH calibration procedures apply to any pH measurement.

One-point calibration: Uses one reference pH solution. Only the zero point is verified, and it is assumed that increasing pH values follow the Nernst effect. This is the fastest calibration method.

Two-point calibration: Uses two pH solutions with at least a two-unit difference. The slope and zero point are determined. As pH electrodes have very good linearity, this method provides accurate results.

Multipoint calibration: Uses three or more pH solutions. The difference should be at least 0.5 pH units. The calibration curve is determined using linear regression or segmented slope calculations. The stability index (R²) should be close to 1 to verify accuracy. Alkaline buffers should be checked for freshness due to higher error sensitivity.

Three-point calibration using Dawn buffer solutions (pH 4, 7, and 10) increases accuracy for most pH measurements.
