Luggin Capillary Tube, 10mm & 14mm OD, 3.3 Borosilicate Glass

Engineered for precise electrochemical research, this Luggin capillary tube minimizes $iR$ drop (ohmic voltage drop) during three-electrode cell potential measurements. Fabricated from high-purity 3.3 borosilicate glass, the capillary provides a fine sensing tip that allows reference electrodes to be positioned extremely close to the working electrode surface without disturbing current distribution. Available in standard 10mm and 14mm outer diameter variants, with custom dimensions available upon request.

Key Features:

• Precision iR Drop Reduction: Designed with a fine capillary tip to bring the reference electrode potential sensing point adjacent to the working electrode, drastically reducing ohmic drop errors.
• Premium 3.3 Borosilicate Glass: Built from high-purity borosilicate glass to deliver superior chemical resistance against harsh electrolytes, acids, and alkaline solutions.
• Standard 10mm & 14mm OD Options: Precision-molded in 10mm and 14mm outer diameter sizes for seamless integration with standard electrochemical cells and cell tops.
• Custom Dimension Support: Custom capillary lengths, tip geometries, or tube diameters can be tailored to bespoke cell configurations by contacting customer support.
• Exceptional Optical Clarity: Clear glass construction facilitates easy visual inspection of internal liquid junctions and electrolyte filling to prevent bubble entrapment.
• Broad Electrochemical Utility: Ideal for cyclic voltammetry, corrosion testing, battery material research, and electrocatalysis studies.
