Catalog Number - 04050-C

The 04050-C Simplus Capillary is an untreated fused silica capillary designed for capillary electrophoresis (CE), providing natural electro‑osmotic flow (EOF) and consistent separation behavior.

Manufactured with extreme precision and excellent concentricity לאורך the full length, this capillary ensures uniform performance and reproducibility. The polyimide outer coating provides durability and flexibility, making it well suited for routine CE workflows and method development.
