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.

Carbonate Borax Free Buffer Solution
Supplier: REAGECON
This range of Reagecon pH Buffers are sodium tetraborate (Borax) free. They are not subject to classification by EU regulatory authorities as toxic to reproduction under CLP category 1B. Similar in approach to the existing range of Reagecon Mercury Free Buffers, these Buffer Solutions have been developed to enhance user choice and allay safety concerns, without any impact on fitness for purpose or product performance.
