Formalin buffered with sodium chloride, or sea water, for marine histology also has a pH of 7.6. Whilst neutral buffered formalin has a pH of 7. pH is very important because the further a fixative is from the pH of body tissues the more distortion you can get in the tissue at the cellular level. Buffering your fixative is also better than
10% neutral buffered formalin is a general histological tissue fixative. Contains formaldehyde buffered to a neutral pH. DETAILS Use: Required for tissue/specimen fixation. For laboratory use only. Hazards: contains paraformaldehyde, chemical known to cause cancer. Handling: with care. Warning! Harmful if swallowed, inhaled or absorbed to skin. Fixation and Fixatives - Popular Fixative Solutions Most frequently the routine fixative will be neutral buffered formalin with other agents used for bone marrow trephines (perhaps a zinc formalin), renal biopsies, frozen sections etc. Buffered formalin is widely used because it is probably the most flexible of agents. It can be incorporated into the processing schedule on enclosed tissue Histopathology Solutions - Serosep

Tissue Fixation with Formalin. Fixation is the single most important determinant of high quality histological sections. 10% neutral buffered formalin is the most widely used fixative for routine histology. There are many variables when using formalin as a tissue fixative. pH level – Ideal level is between 6-8
