Search Trigger Header Search Field English Analytical Instruments Around the world, designers and manufacturers of liquid handling, liquid chromatography, mass spectrometry, and clinical analysis equipment trust our springs and seals to prevent leakage, contamination, and system breakdown. Our products have supported some of the biggest performance advances in this industry. Products for Analytical Instruments Bal Seal® Reciprocating Flange Seal Our reciprocating flange seals, which combine proven Bal Spring® canted coil spring energizer technology with advanced polymer formulations, are proven performers in high performance liquid chromatography. In pressures from aspiration to 18,000+ psi and temperatures lower than 5 °C, they seal consistently for more cycles, making better sample resolution and faster throughput a reality. Product Features Controllable friction forces Excellent chemical stability in a wide range of media Tight tolerances Available with anti-extrusion backup Carousel arrow left Carousel arrow right Chromatography Applications Laboratory Equipment Applications LIQUID HANDLING MASS SPECTROMETRY CLINICAL ANALYZERS Analytical Industry Achievements Validating Vaccines Designers use our Bal Spring® in mass spectrometers to cut contamination and get more accurate m/z results. With these complex instruments, scientists have tested and validated >1M drugs and vaccines. Testing for Diabetes “False positives” can disrupt lives, destroy productivity, and damage reputations. Our Bal Seal® helps improve the accuracy of clinical analyzers that perform diabetes testing for tens of thousands of patients. Performing Under Pressure From the early days of LC, we’ve helped instrument makers push pressure boundaries in search of more resolution and throughput. Today, we’re designing seals and sealing systems for pumps that generate >22 kpsi. Technical Resources INDUSTRY CATALOG APPLICATION BULLETIN MATERIAL DATA SHEET What’s New?
