Catalog Number - 04071-C25

The 04071-C25 Simplus Capillary is an untreated fused silica capillary developed for capillary electrophoresis (CE), providing natural electro‑osmotic flow (EOF) and consistent, well‑characterized separation performance.

Manufactured with extreme precision and excellent concentricity לאורך the full 25‑meter length, this capillary delivers uniform performance across extended use, making it ideal for high‑volume laboratories and custom cutting into multiple CE capillaries. The polyimide outer coating enhances durability and flexibility, and the capillary is supplied on a plastic, non‑static spool for safe handling and storage.
