Pharma-Clear^® LH Series Platinum-Cured Silicone Tubing

SaniSure Pharma-Clear^® LH Series Platinum-Cured Silicone Tubing is a low-hysteresis platinum-cured silicone pump tubing designed for precision pumping and high-purity fluid transfer in pharmaceutical and biopharmaceutical processes. Manufactured in an ISO 14644-1 Class 7 cleanroom, this tubing is built for repeatable performance in peristaltic pumps, pinch valves, transfer lines, and high-accuracy filling applications.

The LH formulation combines precision extrusion tolerances with excellent pump life to support consistent flow through repeated compression cycles. The tubing is translucent for good clarity, tasteless and odorless, and contains no phthalate plasticizers or peroxides that can leach into transported fluid. Double-bagged packaging also supports cleaner handling in controlled production environments.

Available in standard and custom sizes, Pharma-Clear LH tubing is well suited for bioreactor process lines, shear-sensitive fluid transfer, fermentation support, diagnostics, and laboratory use. The product is generally compatible with autoclave, gamma, EtO, and chemical sterilization methods, and SaniSure provides extractables and biocompatibility documentation to support validation and qualification programs.
