Re: nylon embedding bags? The soution


What we do is use a small filter funnel with a large bore stem (powder
funnel) of about 10 mm in diameter.  This is inserted in the mouth of the
bag.  Bag and funnel can then be held in one hand and tissue fragments
poured in with the other.  As the bag drains well it it easy to top up the
specimen container as many times as is neede to get all the tissues into the

The bags become almost translucent after processing so it's relatively easy
to find all the fragments when embedding.
