BUFFER CAPSULES pH 4.0

Buffer Capsules pH 4.0 are designed to prepare a standard pH 4.0 buffer solution for the calibration and checking of pH meters. They are a convenient alternative to the handling and measuring of individual buffer components in routine laboratory work.
The prepared buffer solution gives a defined reference for pH measurement. Regular calibration with a suitable standard guaranties the accuracy and reliability of pH meters in analytical, research, and quality control laboratories.
These capsules are particularly useful in situations where a stable pH 4.0 reference solution is required for routine measurements. Following the recommended preparation procedure guaranties the desired buffer properties and allows for reproducible calibration results.
The product is available in white colored capsules with pH indicator 4.0. Proper preparation using the specified volume and suitable water is important for achieving the intended pH value.
Buffer Capsules pH 4.0 are to be stored and handled as per recommended laboratory conditions. The capsule is to be prepared as directed before use, and the resulting solution is to be used for calibration as per the pH meter manufacturer’s instruction.

Conveniently prepares standard pH 4.0 buffer solution for accurate calibration and routine verification of pH meters.
