BioTight Fitting

In low-pressure fluidic applications, especially in confined or compact setups, sourcing reliable and easy-to-use fittings can be a challenge. IDEX Health & Science addresses this need with BioTight, a press-fit ferrule and lock ring combination fitting specifically engineered for low-pressure environments in life science and diagnostic systems.

BioTight’s low-profile and compact design makes it ideal for tight spaces where conventional fittings may be cumbersome. Designed for convenience, it offers true finger-tight usability, eliminating the need for high torque sealing and simplifying installation in dense instrument configurations. Its press-fit mechanism allows for secure, repeatable connections without overtightening, ensuring consistent and reliable performance.

Made entirely of PEEK, a biocompatible and chemically resistant material, BioTight is metal-free, making it suitable for sensitive bioapplications. It maintains seal integrity in systems operating up to 100 psi for 1/8” tubing and 200 psi for 1/16” tubing, making it a dependable solution for a wide range of low-pressure workflows.

BioTight is especially valuable in fields like genomics, next-generation sequencing (NGS), spatial biology, in vitro diagnostics (IVD), and chromatography, where small form factor, ease of use, and chemical compatibility are crucial.

With its torque-insensitive sealing capability and simplified press-fit operation, BioTight delivers both ease and efficiency. Whether you're working in R&D or deploying a commercial diagnostic system, BioTight offers a powerful, compact solution for ensuring fluidic integrity in demanding low-pressure biofluidic applications.
