Saint-Gobain Life Sciences has launched Sani-Tech® STHT®-LT silicone tubing, designed for cold temperature applications. With a brittleness by impact temperature of -114°C and a glass transition temperature of -90°C, this tubing remains flexible and crush-resistant at very low temperatures. These special properties allow for multiple freeze/thaw cycles and reduce the risk of failure in cold storage, cold chain logistics, and freeze/thaw applications. The tubing contains no fluoropolymers which puts it in alignment with evolving material regulatory standards in bioprocessing.

MALVERN, Pa., Jan. 19, 2026 /PRNewswire-PRWeb/ -- Saint-Gobain Life Sciences is pleased to announce the launch of our latest innovation, Sani-Tech® STHT®-LT, a new silicone tubing specifically engineered for the rigorous demands of cold temperature applications.

STHT®-LT was designed to overcome the physical limitations of traditional tubing, which often becomes brittle and susceptible to damage in low temperatures. Instead, this new formulation remains flexible and crush-resistant, ensuring integrity throughout cold storage, cold chain logistics, and freeze/thaw applications. This reduces the risk of failure in single-use tubing for these critical applications.

Sani-Tech® STHT®-LT offers key advantages over traditional fluid transfer tubing, including:

• Low temperature performance: With a brittleness by impact temperature of -114°C and a glass transition temperature of -90°C, STHT®-LT withstands extreme cold without compromising its structural integrity.
• Enhanced reliability: STHT®-LT is validated to maintain its integrity through multiple freeze/thaw cycles, ensuring drug substances remain safe during complex conditions.
• No fluoropolymers: Formulated without fluoropolymers, STHT®-LT aligns with sustainability goals and evolving regulatory standards in bioprocessing, ensuring long-term compliance for manufacturers.

"Cold temperature applications are a key focus for Saint-Gobain Life Sciences," says Aaron Updegrove, Managing Director, BPS Fluid Transfer Technologies. "The new Sani-Tech® STHT®-LT tubing demonstrates our ability to innovate and offer new solutions for critical applications. It will bring improved performance and risk reduction to all cold storage applications that use it."

Saint-Gobain Life Sciences' expertise in material science and deep understanding of bioprocessing needs are embodied in Sani-Tech® STHT®-LT. The superior cold temperature performance ensures reliable and uninterrupted operations. Additionally, the ability to withstand multiple freeze/thaw cycles further demonstrates its reliability and robustness. STHT®-LT adheres to relevant industry standards, providing the assurance needed for critical applications.
