8 μm Orifice PET Emitters Crafted from 20 μm ID, 360 μm OD fused silica tubing and precision pulled-etched to an 8 μm orifice. Emitters are available in various lengths with Clean- Cut or polished ends. Key Features Low Back Pressure: Minimal additional pressure despite the smaller orifice. Ultra-Smooth Surface: Chemically etched for a uniform, clean finish. Superior Spray Stability: Thin-wall design prevents wetting and supports ultra-stable sprays. Polished Inlet: Ensures optimal connection and sealing, minimizing dead volume. Versatile: Suitable for workflows with flow rates as low as 50 nL/min. Specs Length: 50 mm. Part Number: EMPA ID: 20µm. Opening/Orifice: ~8µm. Legacy part number: C205. Ideal for enhanced-sensitivity proteomics, metabolomics, and other nano-ESI workflows, these PET emitters provide consistent, precise sprays and reliable performance for demanding analytical applications.
