Flux dispensers are used to apply flux in soldering applications. For large soldering areas, flux is typically applied from a jar by hand with a spatula or other implement. For more precise applications, a dispenser is necessary. Flux dispensers are commonly available in the form of pens. They can come prefilled with flux and are generally disposed of after use. Squeeze bottles are another dispensing method and come fitted with needle-point dispensing caps. They contain an initial amount of flux and can be refilled once emptied.
