Eprinex wormer/debugger-Warning & Hints when using

I'm not sure if this is the right place for this, but if not, maybe someone can move the post where it belongs.

I love Eprinex since I know for sure who's been treated & who hasn't. However, I learned a few hard lessons the first time I used it.
#1 Eprinex is expensive so I poured some into an old washed-out prescription bottle to draw from. I used a syringe sans needle to draw out & squirt on the neck. The first thing that happened was that the Eprinex ate away the numbers on the outside of the syringe. I went through several syringes this way.
#2 There was still some Eprinex in the script bottle when I quit for the day so I left it for doing another batch the next day. Whoops! The Eprinex ate through the bottom of the script bottle & I had orange colored Eprinex floating around in my container. The orange plastic had mixed with the Eprinex. That is powerful stuff!
As a solution, I am now using a small plastic cap to draw the Eprinex from, & I try very hard not to get any on the body of the syringe. I find it easier to measure the right amt. when I use Diabetic syringes but the needles are too tiny so I use pliers & pull them out first. Still, after doing several chickens, the Eprinex seems to do something to the rubber tip that makes it very hard to squirt out so I have to switch to a new syringe. Next time I dose, I'm going to try having a soapy solution & rinsing the syringe every few doses. Or maybe some WD-40? Anyone have a similar experience that has solved the problems?

I've not used it like that, but it seems to me you can buy small glass dropper-bottles with glass tubing that would keep it from eating away anything. Just be sure not to suck it up into the bulb. You only use a few drops on the back of the neck, right?

Been there,done that. I use a glass eye dropper that I buy from the drug store. I mark the correct dose with tape and don't draw it into the rubber.
