Buffers
Resisting pH changes, buffers protect samples when acids or alkali is added. Powder and liquid forms efficiently track proteins during electrophoresis isolation and separation. The salty buffers can also be used to calibrate and standardize pH meters for accurate readings. Blocking substances stop antibody attachment to membrane free sites that would produce an interfering background. In various concentrations to fit any need, the buffers may come in liquids or dehydrated formats.

Buffer solutions
Supplier: Hanna
Solutions in sachets ensure optimum precision. The plastic-coated sachet provides a perfect liquid seal and good protection from light. The solutions should only be used once to avoid any danger of contamination. They also satisfy the requirements of the GLP and ISO standards. They have been adjusted using a pH meter that has been calibrated according to the NIST standards.
