Our Bal Seal® spring-energized seals are custom-engineered for HPLC plunger pumps, providing reliable service at pressures from aspiration to 20,000 psi (1379 bar) at 70 ºF (21 ºC), while providing superior protection against contamination. Download our HPLC plunger pump application bulletin to learn more. What is HPLC? High-performance liquid chromatography (HPLC) is a technique...
Seals play a critical role in the accurate and proper functioning of HPLC and UHPLC pumps. Various factors can impact the success of HPLC pump sealing, so it helps to understand how the type of liquid chromatography you’re working with can affect seal design recommendations. The presentation below will provide a brief overview of:...
The Bal Seal provides consistently low friction for more than 1 million cycles to meet demanding PM requirements. Precision-machined from PTFE or polyethylene materials, our seal is compatible with the wide variety of solvents and buffers used in (U)HPLC equipment. The seal’s Bal Spring energizer, with its individual canted coils, provides consistent force that...
Recently, a seasoned mechanical engineer at Motiv Space Systems told us, “When I work with you, I don’t have to think about seals.” That’s music to our ears, because it means we’re helping designers stay focused on bigger things – like landing a rover on Mars. But maybe you’re not quite ready to let...
If engineering challenges are keeping you from getting more out of your ventilator designs or retrofits, our Bal Seal® spring-energized seal could be just the solution you’re looking for. Check out this short video to find out why. The Bal Seal® meets requirements for biocompatibility (USP Class VI, ISO 1993-5) and auto-ignitability, while minimizing...
This short presentation examines the relationship between seal choice and pipettor equipment performance, and it addresses important design criteria, such as hardware surface finish and seal geometry. It also suggests some ways to avoid common sealing mistakes that can cost you time, money, and market share. Selecting Seals for Better Pipettors from BSEmarketing
Looking for a secret weapon that’ll take your multi-channel pipettor design to the next performance level? Check out this short video, and you’ll learn how a custom-engineered Bal Seal® spring-energized seal, with its optimal balance of low friction (<2 lbs) and sealing effectiveness, can promote more accurate, consistent volume delivery for >100,000 cycles. You’ll...
In arrays with 1 to 384 channels, multi-channel pipettors draw a slight vacuum to pull and dispense liquids at very precise volumes into a designated container, increasing the reproducibility and speed of tests and trials. Inaccurate dispensing can invalidate tests, resulting in lab downtime and lost profit.
Performance requirements for in vitro diagnostics (IVD) equipment—including clinical, hematology, and urine analyzers—are outpacing capabilities. Increasingly, the IVD industry is seeking equipment that lasts at least three years or more compared with the existing standard one-year maintenance program. This demand for extended service life and less-frequent maintenance cycles is forcing design engineers to take a closer look...
Designing clinical analyzers that deliver consistent, long-term service, efficiency, and accuracy is one tough job. But choosing the right seal can make it a lot easier. That’s why we’ve prepared this short presentation for you. It examines the relationship between seal selection and the performance of hematology, urinalysis, and other analyzer types, and it...
