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

Enduris® High Pressure Sealing System

Our Enduris® high pressure sealing system combines proven Bal Spring® canted coil spring technology, advanced polymer formulation, and a precision-engineered backup element to deliver pump sealing performance that lasts. It offers OEMs the ability to increase liquid chromatography throughput and sample resolution while significantly reducing equipment downtime.

Product Features

Maintains chemical stability in all UHPLC media
Backup supports seal, prevents extrusion
Superior extrusion resistance at 20,000+ psi

Bal Spring® Canted Coil Spring

Our Bal Spring® canted coil spring mechanically fastens, conducts electricity, and shields sensitive electronics from EMI/RFI. Its independent coils, which serve as multiple contact points for optimal current carrying capability, ensure consistent, reliable connection—leading to less contamination, more accurate m/z measurement and minimal downtime.

Product Features

Superior conductivity & power density
Compact, space-saving profile
Wear-resistant for minimal contamination
Customizable insertion/removal forces

Chromatography Applications

Chromatography Pump Rinse Systems

Bal Seal® spring-energized reciprocating seals remove residual media in the system and eliminate contamination that can impact test accuracy.

HPLC & Chromatography Pumps

In pressures from aspiration to 18 kpsi, and temperatures lower than 5 °C, Bal Seal® reciprocating flange seals seal consistently for more cycles.

UHPLC Pumps

The Enduris ® High Pressure Sealing System helps improve equipment throughput and efficiency.

Laboratory Equipment Applications

Multi-Channel Pipettes

The Bal Seal® spring-energized seal improves accuracy and product consistency in precision dispensing applications.

Analytical Instruments Application Lab Equipment

Capillary Tubes

Bal Spring canted coil springs help achieve better, more consistent alignment of capillary tubes.

Vacuum Chambers

Bal Seal spring-energized seals separate the ionization and vacuum chambers in mass spectrometry equipment for improved test accuracy.

Hematology Equipment

In analyzer pumps, Bal Seal® spring–energized seals control weepage and help prevent the saline-rich reagent from forming crystals.

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.
