pH calibration buffers

pH calibration buffers are specially prepared solutions that have a known level of acidity or alkalinity, ensuring accurate pH measurements. They are used to calibrate pH meters, which are tools that measure how acidic or basic a solution is. By testing the pH meter with these buffers, users can adjust the device to ensure precise readings when analyzing unknown solutions. The buffers typically have pH values like 4.0, 7.0, and 10.0, covering a wide range of conditions. This calibration process helps maintain the accuracy and reliability of pH measurements in various scientific, medical, and industrial applications.
