Buffered acetone fixative

All of our ready-to-use buffers are:

• Conveniently packaged.
• Prepared fresh for each order.
• Economical and time-saving.
• Desired pH should be specified when ordering.

The buffer is a vehicle for the fixative and requires certain properties:

1. To maintain 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.
2. The ionic constitution to prevent the extraction of cellular components, or the deposition of precipitates of fixative chemicals.
