Water for capillary electrophoresis (CE) is a critical consumable used in CE system preparation, capillary conditioning, buffer preparation, and routine operation. This category includes CE‑grade water formulated to support reproducible separations, stable electroosmotic flow, and reliable analytical performance.
Capillary electrophoresis is particularly sensitive to ionic contamination, dissolved gases, and trace impurities. Using water that meets CE‑specific purity requirements helps minimize background noise, reduce variability, and support consistent migration behavior across methods.
Designed for CE Workflows
CE‑grade water is commonly used for:
Capillary rinsing and conditioning
Buffer and electrolyte preparation
System priming and flushing
Routine CE operation and maintenance
Water quality plays a direct role in separation efficiency and method robustness. CE‑grade water helps reduce unwanted ionic contributions that can affect electroosmotic flow, current stability, and peak reproducibility.
Supporting CE Tools & Consumables
In addition to CE‑grade water, this category may include supporting tools and accessories used to assist with capillary electrophoresis workflows, such as:
Manual hand pumps for gently introducing liquids into capillaries
Capillary cleaving tiles for clean, controlled capillary cutting
Magnification tools for capillary inspection
Specialized CE solutions used for conditioning or maintenance
These items are intended to simplify routine CE handling and reduce manual variability during preparation and operation.
Applications & Use Cases
CE‑grade water is used in:
Pharmaceutical and bioanalytical CE methods
Clinical and environmental CE analysis
Academic and research laboratories
Method development and troubleshooting workflows
Selection of CE‑grade water and supporting tools should consider instrument sensitivity, buffer composition, and analytical reproducibility requirements.
