WWP - Square Tubing with TSP coating for CE

Delivering industry-leading performance including tight ID and OD tolerances, Polymicro Technologies™ polyimide coated WWP capillary tubing ensures precise flow-rate control of liquids and gases for Scientific, Industrial and Medical application

Polymicro Technologies now offers a squared cross-section, flexible fused silica capillary tubing with a durable polyimide coating.
Features and Benefits
  • Eliminates the need to correct for the optical effect of curved capillaries in Capillary Electrophoresis (CE)
  • Offers larger effective internal surface area
  • Flat sides create 27% more volume and 2x the transverse optical interaction path lenght (using a collimated beam) than that of a round capillary configuration
  • Ideal geometry for use in on-column orthogonal fluorescence detection schemes
  • Interfaces easily with existing fitting technologies
  • Operation up to 350°C

Scientific Applications: Analytical Chemistry, Chromatographyic Techniques, Micro- and Nanofluidics, Mass Spectroskopy Interfaces
Industries Applications: Package Leak Testing, Evaporative Cooling Systems, Petroleum Analysis, Catalytic Research
Medical Applications: Precision Drug Delivery, Flow Control Systems, Clinical and Diagnostics Devices, Wearable Drug Delivery Devices Scientific
