Recently joined the IV league, and need some pointers before I get myself hurt.
Ive been doing a lot of reading up on this topic so please don't blast me with a "utfse", as my technique is a bit different from the norm.
Since I lack luer-lock syringes, I've just been backloading a regular 1mL 100 unit insulin syringe to filter.
Here's my procedure:
dissolve product in COLD water -> backload with a designated reused "backload" syringe, push through (reused) "filter" rig packed with ~1/2 cm of cotton -> bring filtrate to light boil then boot up with a brand new rig.
Now my quesiton is: should I be reusing my filter rig at all? Or should I use it once and toss it?
Since I'm sterilizing AFTER it passes through the filter, I should be safe from cotton fever, correct?
So far I've reused it three times in ~12 hours with no issue, but I fear that bacteria could be festering in the filter medium given enough time - and a brief 1-2 second bubbly blast with a lighter may be insufficient to entirely sterilize the solution if this were the case.
I've been enjoying the ride so far, but I really don't want to push my luck.
Sorry if this has been covered before, but its difficult to dredge up information on this issue in particular.
Thanks.
