Buffer Solution pH 4.00 (Twin Neck Format) is manufactured by Reagents. A buffer solution is commonly used in biological laboratories to maintain the pH of a reagent. Buffers have the capacity to resist changes in pH when an acid or an alkali is added to it. Chemically, a buffer consists of a weak acid and its conjugate base, or vice versa. Even in our body, several buffers continuously regulate pH according to the requirements of the system. For example, the blood contains a buffer known as the blood plasma buffer. In experimental systems, buffers Tris, MOPS and citrate are used to maintain a certain desired pH. Reagecon produces buffers which confer to the IUPAC pH scale standards and offers traceability for consistent and universally accepted results. The buffers are manufactured such that they are stable and provide a long shelf life. The pH 4.00 buffer is colour coded and is red in colour. It is tested at 25 C

The buffer is available in the twin neck bottle format. This packaging prevents contamination and it eliminates the need for a separate measuring container during electrode calibration. This allows for correct measurement of buffer quantities and no wastage. It is easier to carry and can be used for field work.
