Прадукт скончаныview

The Apera Instruments pH 4.00 Calibration Buffer Solution is a high-quality standard designed for accurate pH meter calibration. This 16 oz. bottle contains a solution traceable to NIST Standard Reference Materials (SRMs), ensuring reliability and precision in your measurements.

Асноўныя функцыі ўключаюць у сябе:

• Дакладнасць: Reported values are accurate to +/- 0.01 pH at 25 °C.
• Quality Manufacturing: Produced in an ISO 9001:2015 certified facility using high-purity reagents, deionized water, and certified analytical balances in a temperature-controlled environment.
• Ідэнтыфікацыя: Color-coded for quick and easy identification.
• Тэрмін прыдатнасці: Double-sealed with a 2-year expiration from manufacture for an unopened bottle.

Настройка і падрыхтоўка

Before using the pH 4.00 calibration buffer solution, ensure your workspace is clean and free from contaminants. Follow these steps for optimal preparation:

1. Inspect the Bottle: Verify the bottle is sealed and undamaged upon receipt. The solution is double-sealed for protection.
2. Праверце тэрмін дзеяння: Locate the expiration date on the bottle label. Do not use the solution past its expiration date.
3. Temperature Acclimation: Allow the buffer solution to reach the ambient temperature of your calibration environment before use. This is crucial for accurate calibration, as pH values are temperature-dependent.
4. Gentle Mixing: Gently invert the bottle a few times to ensure homogeneity before opening. Avoid vigorous shaking, which can introduce air bubbles.

Operating Instructions (Calibration Procedure)

This pH 4.00 buffer solution is used to calibrate pH meters. Always refer to your specific pH meter's instruction manual for detailed calibration steps. General steps for using this buffer are:

1. Прамыўны электрод: Before immersing the electrode in the buffer solution, rinse it thoroughly with distilled or deionized water.
2. Апускальны электрод: Submerge the pH electrode into a sufficient amount of pH 4.00 buffer solution. Ensure the electrode's sensing bulb and reference junction are fully immersed.
3. Stabilize Reading: Allow the pH meter reading to stabilize. This may take a few moments.
4. Perform Calibration: Initiate the calibration process on your pH meter according to its specific instructions for a 2-point or 3-point calibration, typically starting with pH 7.00, then pH 4.00, and optionally pH 10.00.
5. Прамыць пасля выкарыстання: After calibration with pH 4.00, rinse the electrode again with distilled or deionized water before proceeding to another buffer or sampле.

Тэхнічнае абслугоўванне і захоўванне

Proper maintenance and storage are essential to preserve the accuracy and shelf life of your pH 4.00 buffer solution:

• Тэмпература захоўвання: Store the bottle at room temperature, away from direct sunlight and extreme temperature fluctuations.
• Keep Tightly Closed: Always recap the bottle tightly immediately after use to prevent evaporation and contamination.
• Пазбягайце забруджвання: Never return used buffer solution to the original bottle. Pour out only the amount needed for calibration into a separate, clean beaker. Dispose of any unused portion from the beaker.
• Тэрмін прыдатнасці: The solution has a 2-year expiration from the date of manufacture when unopened. Once opened, its shelf life may be reduced depending on storage conditions and contamination.

Ліквідацыю непаладак

If you encounter issues with your pH meter calibration using this buffer solution, consider the following:

• Incorrect pH Reading: Ensure the buffer solution is at the same temperature as your pH meter's temperature compensation setting or the sample. Refer to the pH/Temperature Reference Chart on the bottle for accurate values at different temperatures.
• Expired Solution: Check the expiration date. Expired buffer solutions can lead to inaccurate calibrations.
• Забруджванне: Verify that the buffer solution has not been contaminated by returning used solution to the bottle or by using unclean beakers/electrodes.
• Electrode Issues: If problems persist, the issue might be with the pH electrode itself (e.g., dirty, dry, or aged). Refer to your pH meter's manual for electrode maintenance and troubleshooting.
