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.

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.

Custom Dimensions

We understanding your application can be unique, our PET 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.
