20µm ID x 365µm OD x 50mm Stinger Fused Silica Emitter P/N - ES5-222

ES5-222 is a five pack of 20µm ID x 365µm OD x 50mm Stinger Emitters which are chemically etched fused silica ESI spraytips with a constant 20µm internal diameter that sprays well at flows from 20-1000 nl/min.  The stinger tips are significantly more robust than pulled tip emitters as they will not clog from particulates that get into the emitter.
