This pH Buffer Solution is a standard calibration solution for pH meters, available in common values such as 4.00, 6.86, and 9.18. It provides accurate and stable pH reference points for regular calibration and verification of pH electrodes, ensuring reliable measurement results in laboratory and industrial applications. Ideal for use in water quality testing, environmental analysis, and general chemistry experiments.

1. pH Meter Calibration: Complete "offset + slope" calibration to eliminate electrode drift and temperature errors.

2. Electrode Performance Check: Verify electrode response and determine if replacement is needed.

3. Water & Environmental Testing: Calibration for water quality analysis, wastewater monitoring, and environmental labs.

4. Food, Pharmaceutical & Industrial Testing: pH calibration for food, beverage, pharmaceutical, electroplating, and chemical industries.

5. Teaching & Research Labs: Reference standard for pH measurement in educational and scientific experiments.

1. Strict Standard & High Precision: Produced in line with national standard specifications, featuring tiny pH value deviation and stable performance among different batches.

2. Complete Three-point Calibration: Adopts mainstream calibration solution values of 4.00, 6.86 and 9.18, covering full pH testing scope to effectively reduce testing deviation.

3. Directly Available for Use: Finished product ready for immediate application without on-site mixing, avoids errors caused by manual preparation and saves laboratory working hours.

4. Sealed and Durable Package: Adopts corrosion-proof sealed bottles, effectively slows down liquid evaporation and prevents external pollution, greatly prolonging storage period.

5. Strong Universal Adaptability: Perfectly compatible with Qiwei brand pH testers, and also fits most mainstream desktop and portable pH meters on the market.

1. Storage temperature: The standard buffer solution is stored in the refrigerator, and the recommended temperature is 2-8 degrees Celsius. Lower temperature can prolong the stability of the solution.

2. Sterile conditions: Before use, ensure that the standard buffer solution is prepared under sterile conditions, and sterile filtration before use. Avoid introducing bacteria, fungi or other microorganisms into the solution.

3. Close container: The standard buffer solution is packed in a tightly sealed container to avoid the entry of air and moisture. Sterile glass bottles or polypropylene bottles are recommended.

4. Light-avoidance: Light-avoidance preservation is very important, especially for light-sensitive standard buffer solutions. In the process of preservation, the contact between solution and light should be minimized.

5. Attention to pollution: Before using the standard buffer solution, it is necessary to ensure that the working table, instruments and other experimental instruments are clean and sterile to avoid solution pollution.

6. Labeling and recording: The name, formulation, concentration, preparation date and expiration date of the standard buffer solution are clearly marked on the container. And timely update records, and in accordance with the requirements of the expiration date for processing.
