Desired pH should be specified when ordering.
Buffers are vehicles for fixatives and require certain properties:
- Maintenance of constant pH during the time of the fixation. The pH of the fixative in EM is adjusted using the buffer system chosen; e.g. range 6.5-8.0.
- The ionic constitution to prevent the extraction of cellular components, or the deposition of precipitates of fixative chemicals.
