Using Ampules

[bleepbleep]

Hi,

I have always used vials in the past. I am wondering with an ampule what is different?

I am aware you need to snap the top off and also that unlike a vial it does not matter whether or not you fill the syringe with air to create some air pressure. I am wondering do ampules usually have rubber stoppers after the top part is broken? If not, how is it possible for people to draw upside down with the medication pouring out?

They can use it upside down because of air pressure. Not a physics guy, just know it has to do with that. No, there is no rubber stopper with a ampule. Once you pop the top, you use it all. Go get you an amp opener off the net, it will save you quite a hassle.

An amp can be a PITA if you are not use to them. You can break them and end up with glass inside the amp. You have to draw holding it upright. The biggest issue is opeing and drawing...everything else is the same.

You can use a pen cap to break the top off an amp or get an appropriate amp cutter.

You use a 'draw pin'...typically a 18 or 20 g to draw the solution into your syringe.
