Standard - Constant i.d. Etched-Tip (CET) ESI Emitters

This is our original "MicrOmics etched constant ID emitters" Dr. Ryan Kelly developed in the early 2010s.

Our CET Emitters are designed with a constant inner diameter and no inner tapered tip to reduce clogging, enhance flow consistency, and provide highly reproducible spray characteristics and sensitivity.

Specs

• Constant Inner Diameter: 20 µm.
• Length: 50 mm.
• Most Commonly size for most nano-LC workflow
• Ultra-Smooth Surface: Chemically etched for a uniform, clean finish.
• Stable Spray: Optimized for <100 nL/min (10 µm) and higher flow rates (20 µm).
• 5pk
• Legacy part number: EM-20-360-5pk 5.5 cm long
• Part number: D205

Ideal for high-sensitivity proteomics, metabolomics, and other nano-ESI applications, these emitters offer the consistency and durability required for demanding analytical workflows.
