Catalog Number - 04075-C

The 04075-C Simplus Capillary is an untreated fused silica capillary designed for capillary electrophoresis (CE), providing natural electro‑osmotic flow (EOF) and consistent, well‑understood separation behavior.

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