Heat syrup SLOWLY to 185-190 - do NOT go over 190 or you are making more nitre. If your syrup is already crystal-free then it should remain so. Normally you have to go like 225 for crystals, and you do not to go anywhere near 225 for rebottling.
BTW I don't use plastic containers, I am going to assume you are using glass jars. Decant carefully into clean sterilized containers and new lids. If you're using glass, fill to the very brim, tighten lid to fingertip tightness and lay on its side (I use an aluminum tray in case of any leaks) so the seal forms. And leave it. Once it's cooled it'll be safe to set upright.
