Capillary, Controlled, Low Flow, 50um ID by 1 meter. MICROSOLV Brand. 1 EA.
Additional Info:
The 04650-LF MICROSOLV Low Flow Capillary is a fused silica CE capillary with a covalently bonded polymer containing sulfonic acid groups, creating a reduced negative surface charge.
This results in significantly slower electro‑osmotic flow (EOF) compared to untreated capillaries, allowing analytes to migrate with longer interaction times and improved separation control. Migration is governed by both reduced EOF and electrophoretic mobility.
Supplied as a 1‑meter length without finished tips, this capillary can be cut to the required length for compatibility with a wide range of CE instruments.
