Laboratory Experiments on Rats
"Histologische Untersuchung bei Versuchsende
Nach Durchfixierung wurden die Organe zurechtgeschnitten oder Proben entnommen und im Entwässerungsautomaten weiterbearbeitet."
From a text about an experiment on lab rats. This is describing what happens after they're put down. The text has previously mentioned about organs being "fixiert" in formalin, which I guess is just fixed, but I have no idea what "Durchfixierung" is and can't find a translation for it (or the verb "durchfixieren" anywhere). Google searching for "fixed through" in relation to animal organs in experiments is utterly inconclusive. TIA for any light you can shed on this decidedly obscure word.

Comment: "Complete fixation it is! Thanks for a thorough and convincing answer SJLD, and thanks to the peer graders for making my decision that much easier. But thanks also to Zareh for setting me straight about fixation. Appreciate everyone's help."

immersion fixation
This could be "immersion fixation", the other two major types being
"heat fixation" and "immersion".

**Immersion**: The sample of tissue is immersed in fixative of volume at a minimum of 20 times greater than the volume of the tissue to be fixed. The fixative must diffuse through the tissue to fix, so tissue size and density, as well as type of fixative must be considered. Using a larger sample means it takes longer for the fixative to reach the deeper tissue. Best in a slight vacuum.
