[Histonet] Pre-filled 10% NBF containers

[Jackie M O'Connor]

Can someone give me an idea which company might sell pre-filled formalin 
containers that are actually filled with formalin?

Most of the pre-filled containers I've been buying are only filled with 
1/2 the volume of the container. 

I'll be happy if I can get a 60ml vial with 40 ml of formalin - 30 just 
isn't enough.   I know, I know - 1:20.
