Biopsy specimens removed for examinations are immediately placed in

2) 10 % formalin
3) Hydrogen peroxide
4) 1 % formalin

Option 1

Option 2

Formalin, specifically 10% neutral buffered formalin, is the standard fixative used for preserving biopsy specimens. It helps to maintain the tissue architecture and cellular details, making it suitable for histopathological examination. Ethanol is not typically used for routine tissue fixation as it can cause tissue shrinkage and distortion. Hydrogen peroxide is not a fixative and is used for different purposes, such as disinfection. A 1% formalin solution is too dilute for effective fixation.
