Buffer Solution pH 7.00 is manufactured by Reagecon. Buffer systems are aqueous solutions which can resist a change in pH when an acid or an alkali is added. Buffers are composed of a weak acid and its corresponding conjugate base. Such systems are routinely used in biological laboratories to allow consistent pH of the experimental environment. This is essential because several biological reagents, enzymes, proteins and other biomolecules require a certain pH condition for its optimum function. Hence pH Buffers are included into these reagents to resist changes in pH. Further, a consistent pH introduces reproducibility. 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 7.00 buffer is colour coded and is yellow in colour. It is tested at 25 C Manufacturer: Reagecon pH: 7.00 0.01 Colour: Yellow Shelf Life: 24 months Quantity: 500 mL Quality Assurance: ISO 17025 and ISO 9001:2008 certified. 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.
