Capillary electrophoresis (CE) supplies and accessories designed to support high‑resolution separations, reproducible performance, and reliable detection. This category includes bare and coated fused‑silica capillaries, detection window tools, and supporting components used in analytical and research‑grade CE workflows.
Capillary electrophoresis separates analytes based on charge‑to‑size ratio under an applied electric field, using narrow‑bore fused‑silica capillaries to achieve efficient heat dissipation, high separation efficiency, and rapid analysis. Proper selection of capillaries and accessories is essential for maintaining stable electroosmotic flow, consistent migration times, and reliable detection.
Capillaries for Capillary Electrophoresis
This category includes CE capillaries available in multiple internal diameters, lengths, and surface formats, allowing laboratories to tailor separations for specific analytes and methods. Options include:
Bare fused‑silica capillaries for general CE applications
Coated capillaries designed to control electroosmotic flow or reduce analyte–wall interaction
Controlled‑flow and zero‑flow variants for specialized separation requirements
Capillaries are manufactured with precise dimensional control to support compatibility with standard CE instruments and reproducible analytical performance.
CE Window Maker & Detection Tools
The CE Window Maker is a dedicated tool used to create optical detection windows in polyimide‑coated fused‑silica capillaries. This allows UV or optical detection without compromising capillary integrity. Detection windows can be produced consistently and cleanly, supporting accurate signal measurement in CE systems.
Supporting Components for CE Workflows
Additional supporting components are available to assist with capillary handling, preparation, and maintenance, helping laboratories configure and maintain reliable capillary electrophoresis systems. These products support method development, instrument compatibility, and routine analytical use.
Applications & Use Cases
CE supplies in this category are commonly used in:
Pharmaceutical and bioanalytical research
Clinical and environmental analysis
Food and chemical testing
Method development and academic research
Selection of appropriate CE capillaries and accessories should consider analyte chemistry, buffer systems, applied voltage, and detection requirements.
