Capillary tubing for pharmaceutical analysis

Polymicro Technologies' capillary tubing is widely used for on-column analytical techniques such as DNA sequencing, forensics, proteomics and pharmaceutical analysis. By utilising a non-abrasive laser technique, Molex develops strong, clean, durable windows in standard polyimide-coated synthetic-fused silica capillary tubing, or custom-drawn capillary tubing tailored to the customer’s specific inner and outer diameter requirements. Molex uses a range of custom designed laser stations in order to efficiently window small quantities through high volume production. Additionally, the windowed capillaries feature low background fluorescence and smooth optical surfaces.

Joe Macomber, product manager, Polymicro Technologies, comments: “At Molex we are driving cutting edge advances in Polymicro capillary tubing techniques. A staple in the laboratory, our CE products include bulk capillary tubing designed specifically for CE applications and other value-added products such as windowed capillary that simplify column preparation in pharmaceutical applications. Each customer’s unique specifications are thoroughly reviewed to determine the most effective CE capillary design. Polymicro Technologies capillary tubing solutions range from simple cut pieces of standard capillary to complex, multi-capillary assemblies."

In order to develop the speciality tubing, Molex makes use of a wide range of tightly controlled manufacturing processes also include precision cleaving, custom internal coating, and unique cross sectional geometry capillary. Used to help sequence the human genome, Polymicro Technologies multi-capillary assemblies and windowing capabilities are continually utilised in emerging CE based techniques.
