Adding liquid fining agent into fermenter via gas post?

[mscroggi]

I dont *think* this is a stupid question.. if it is.. please ignore

I use an all-rounder fermenter that has the liquid and gas posts. I ferment under pressure (~10psi) and really don't want to crack the lid to put in a fining agent.

I am wondering if it would be practical to find a way to introduce the fining agent into the fermentor through the gas post.

Has anyone tried this? If so what did you use? My thought was to use soda bottle with one of those liquid post caps that I could connect, invert, and squeeze to push the fining into the fermentor (stopping with a tiny bit of liquid left).

Is this stupid?

A lot of people use plastic syringes that they hook up directly to a QD. The benefit of the syringe is you can draw up a gelatin solution with no air in the syringe, so you really are doing it oxygen free. Not sure how you could avoid air getting in if you used a soda bottle.

OH changing the thread search to use 'syringe' found a discussion on the matter. Awesome! Thanks!!
