Buffer solution pH 4

A buffer solution is an aqueous solution containing a mixture of a weak base and its conjugate acid or vice versa.  It is a clear colourless liquid. Krins Life Sciences offer the Buffer solution for testing methods, sample storage, and calibrating pH range  3.95 – 4.05.

The change in pH of Buffer Solution is very little when a little amount of strong acid or base is added to it. Buffer solutions are essential in biology for keeping the right pH for proteins to work. Buffer is a type of solution which resists any change in the activity of an ion upon adding substances that are likely to change the activity of that ion.

Buffer solution is very useful for keeping pH at nearly constant value and there are many systems that use buffering for pH regulation. If the pH of a solution increases or decreases too much, the efficacy of an enzyme decreases in a process. Many biological samples used in research are kept in a buffer solution. The buffering agents are used in chemical analysis and to maintain stability of various dosage forms. In analytical procedures, it is used to establish hydrogen-ion activity for the calibration of pH meters. It is also used in fermentation processes.

Krins lifesciences has different pH buffers(pH 7.00, 9.2)  besides pH 4.00 and it is tested for significant accuracy to be used as a calibrating buffer for pH Meter. For any buffer needs of laboratory or bulk qty please call or email Krins lifesciences, one of our representative will be happy to assist you.
