here's a couple pics for you ...
i have others but they are on another computer that has crashed

hope these help
i store my rat glands in yogurt containers with lids until putting them in quart jars covered in vodka/glycerine mix ... works for me

pretty much all others all others i just freeze in tight sealed clean containers
beaver castor just gets double bagged in zip locs and frozen until dried
oil sacs get frozen too ... then at a later time squeezed into glass jars ... and the empty sacs ground to be used in bait formulation
i even save otter glands ... frozen then put into glass jars and rotted down to a liquid * see last pic that quart jar was 2/3 full about 30 otters worth see what it ends up being mmm mmm good
MINK gland locationremoval is pretty simple ... using a sharp knife cut the little sac away by cutting close to the carcass and around ... making sure not to cut into it ... a lot easier doing it than trying to tell ya how lol

MUSKRAT glandsremoval of rat glands is even more simple ... you cann gentley pull as you cut the connecting membrane ... once again making sure you do not cut into the gland ...
