10% Neutral Buffered Formalin

Q: Does Richard-Allan Scientific 10% Neutral Buffered Formalin contain 
     methanol and, if so, at what percentage?
A: Yes. Methanol is added to prevent formaldehyde polymerization to
     paraformaldehyde. There is less than 1% of methanol v/v.

Cal-Rite
Q: Does Cal-Rite have to be changed daily?
A: For faster results, Cal-Rite should be changed daily.

Q: Is Cal-Rite fast acting?
A: Cal-Rite is ideal for diagnostic specimens that require rapid processing
     including bone marrow biopsies (3-4 hours). Larger specimens will require
     a longer decalcification time.

Decalcifying Solution
Q: Is Decal Solution fast acting?
A: Decal Solution is hydrochloric acid based and fast acting with bone marrow
     biopsies taking less than two hours and routine surgical specimens
     decalcifying in approximately 2-4 hours.

Q: How often does Decal Solution need to be changed for best results?
A: Decal Solution should be changed after the first two hours of decalcification.

Pen-Fix
Q: Can tissue specimens be stored in Pen-Fix?
A: No. Pen-Fix is not recommended for the storage of tissue because of 
     potential over-dehydration, especially in smaller specimens.

Q: Can Pen-Fix be used with immunoperoxidase techniques?
A: Yes. Historically there have been no problems with the masking of antigen
     sites.
