ARKPEEK-1000 Capillary Tubing – Precision Fluid Handling at Micro Scale

Engineered for the most demanding microfluidic and analytical applications, our ARKPEEK-1000 capillary tubing provides unmatched performance in ultra-small diameters. Manufactured from virgin, unfilled PEEK polymer, this tubing combines exceptional purity with the material's inherent advantages - making it the ideal choice for critical fluid paths where conventional tubing fails.

Key Features & Benefits

Ultra-Small Diameters Available: Ranging from 0.005" to 0.060" (127μm to 1.52mm) for precise fluid control

Unmatched Purity: ARKPEEK-1000 material contains no fillers or additives, ensuring zero interference with sensitive analyses

High-Pressure Capable: Maintains structural integrity at pressures exceeding 8,000 psi for micro-HPLC and UHPLC applications

Exceptional Surface Finish: Smooth inner bore (Ra < 0.2μm) minimizes adsorption and flow resistance
