CET Emitters

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.

Key Features

• Constant Inner Diameter: Available in 10 µm and 20 µm, other ID possible upon request.
• Ultra-Smooth Surface: Chemically etched for a uniform, clean finish.
• Polished Inlet: Ensures optimal connection and sealing, minimizing dead volume.
• Stable Spray: Optimized for <100 nL/min (10 µm) and higher flow rates (20 µm).

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

Custom Dimensions

We understanding your application can be unique, our CET Emitters can be customized for non-standard dimensions, i.e., length, ID, OD, opening/orifice and etc. Please contact us or leave your request in the Order special instructions in the checkout page.
