SilicaTip™ Emitters

SilicaTip emitters are capable of hundreds of hours of continuous operation (more than 800 hours with MeOH/water/acetic acid mobile phase) without a loss of coating. These emitters are engineered for continuous-flow nanospray in a 20-1,000 nL/min. range. Each SilicaTip must pass rigorous video inspections and conform to stringent specifications to ensure the highest performance nanospray emitter.

Pre-Cut SilicaTips

SilicaTip emitters are also available pre-cut and polished to the exact length needed for your particular mass spec/source configuration, whether for Waters, Thermo, or AB SCIEX systems. Pre-cut means that there is no need to cleave the end of the emitter yourself prior to connection–it's ready to use right out of the box.

Fritted SilicaTips

A fritted SilicaTip (also known as a Self-Pack PicoFrit) provides a nanospray emitter that is virtually clog-free. The fritted SilicaTip is a popular choice when the application demands cleanliness within the fluid path as well as high performance sample preparation methods.
