Silicone Tubing - Sani-Tech® STHT-C Sanitary - Biopharmaceutical Products

Permanently laser marked lot code for total product traceability.

Sani-Tech® STHT®-C is an ultra-pure, biopharmaceutical-grade tubing that has a useful life unmatched by any other known process tubing.

This platinum-cured silicone tubing resists temperature extremes, ozone, corona, radiation, moisture, compression sets, weathering and chemical attack and imparts no taste or odors to fluids transported within it.

Sani-Tech® STHT®-C silicone tubing withstands repeated autoclaving and resists the adherence of blood products and other sanitary fluids. Sani-Tech® STHT®-C, in 1/16" ID and greater, comes with laser marked part numbers and lot codes to provide total product traceability.


The manufacturing process is carefully controlled from receiving through production. Inspection and lot traceability are readily accessible as batch numbers are assigned. All packages are identified by external labeling on both the bag and the high-quality, crush-proof box.


Sani-Tech® STHT®-C is manufactured from the finest grade of silicone materials and is fully characterized, validated and tested to a variety of specifications including USP Class VI criteria, ISO 10993, European Pharmacopoeia 3.1.9, and Japanese Pharmacopoeia – Section 51. For additional compliance data please contact our customer service department. Sani-Tech® STHT®-C has a Master File with the U.S Food and Drug Administration.
