It's at the core of every great achievement and it's the most critical requirement in liquid chromatography pump sealing. We knew this when we set out to design the new, ultra-reliable Enduris™ high-pressure sealing system.
Tested to 2,000,000 cycles at a barrier-breaking 22,000 psi, Enduris combines proven Bal Spring® canted coil spring technology, advanced polymer formulation, and a precision-engineered backup to deliver pump sealing performance that lasts. And lasts.
Enduris offers OEMs the ability to increase LC throughput and sample resolution while significantly reducing equipment downtime. It's the first seal proven to deliver consistent, long-term performance in liquid chromatography pumps at pressures of 22,000 psi and higher.
Machined from blends of ultra-high molecular weight polyethylene or PTFE, Enduris employs a Bal Spring® canted coil spring energizer to promote more uniform wear and longer service life. Its metallic backup element features a design that supports the seal, and prevents extrusion along the inner and outer diameters of the groove. The backup also aligns and centers the seal, ensuring more balanced loading along the seal lips.
Over a 24-month period, the Enduris™ high-pressure sealing system was tested in a laboratory environment under a variety of pressure and media conditions. The graph represents aggregate results, and compares the performance of a typical HPLC seal with the Enduris.
Marathon testing capabilities. Faster throughput. Increased sample resolution and fewer service calls. They're all part of the Enduris performance advantage.
