The pHat™ Buffer Screen is a set of 96 different buffer solutions encompassing 12 different buffer systems at 8 different pHs each ranging in steps of 0.4 pH units from ±1.4 pH units about the buffer pKa. The screen covers the entire crystallization space with buffers ranging from pH 2.4 to pH 11.6.
The buffers are organized according to their final pH so as to facilitate the setup of subsequent refinement screens. The pHat™ buffers can also simply be added to any other 96 formulation screen to add another chemical dimension to the search for optimized crystal growth conditions.

The buffers are delivered in a 96 deep well block plate filled with 1.0 ml of each buffer solution at 10x the recommended final concentration, each prepared with ultra-pure chemicals and water (18.2 Megohm-cm) followed by sterile 0.22 micron filtration.
