Review on 10cc Syringe with Plunger & Tip - SMD291 Chipquik Tack Flux No Clean by Michael Lara

This flux is well suited for both leaded and lead-free solders. Flux dispensing can cause flux to leak through the rubber stopper seal. With the included tip (much larger diameter) this will not happen. I had to use a 30 gram needle to apply the flux to a tiny pad. I'm not going to take the plunger out, clean it, and pour perfectly smooth flowing flux back into the syringe. So far the flux has not seeped back past the end of the open end of the syringe. Hopefully repackaging the syringe isn't as messy as it sounds.
