Hepes, free acid hepes has been described as one of the best all-purpose buffers available for biological research. At most biological phs the molecule is zwitterionic, and is effective as a buffer at ph 6.8 to 8.2. Hepes has been used in a wide variety of applications, including tissue culture. Buffer strength for cell culture applications is usually in the range of 10 to 25 mm. After the addition of hepes ph is adjusted with naoh or hcl. Care must be taken to maintain appropriate osmolality
