Spray tip bore size is what controls the spread and intensity of the nitrogen stream, so most clinicians keep several gauges on hand and match the tip to the lesion. This is the 19 gauge tip, a mid range bore that suits everyday superficial work.
It screws onto the Nitrospray outflow track and can be changed over quickly during a list. Tips wear and block with use, so holding spares of the gauges you reach for most keeps a clinic running.
