What kind of cottons do you have? I suggest if that's all you have you should filter two times or three by
1. Stretch out the cotton (if its q tips) and then roll it into a very tight ball. If you make it a weird ball you will have two sections you suck solution. Out of so try to make it an even ball.
2. Make your shot in the sterile cap and drop the cotton in the cap and pull up solution
3. Dump out old cotton put solution back into cap add a new cotton and suck up again.
4. Make sure you use an alcohol pad over in injection site at least two minutes to dry.
