20µm ID x 365µm OD x 50mm Etched Fused Silica Emitter P/N - EE5-222

EE5-222 is a five pack of 20µm ID x 365µm OD x 50mm Etched Emitters which are chemically etched fused silica ESI spraytips with a constant 10µm internal diameter that sprays well at flows from 20-1000+ nl/min.  The etched tips are significantly more robust than pulled tip emitters as they will not clog from particulates that get into the emitter.
