* Other sizes available upon request.
In bioprocessing, mechanical durability and thermal stability under extreme conditions are critical. 3CON provides highly specialized single-use film solutions specifically engineered for cryogenic environments.
Our materials guarantee maximum process security—from standard deep-freeze storage to the most demanding ultra-low cold chain applications.
Renolit 9101 | LDPE Film:
Reliability down to –80 °C
Renolit 1400 | EVA Film:
Cryogenic Resistance down to –170 °C

With our patent-pending, validated laser welding technology, 3CON enables fully flexible, tool-free manufacturing of single-use bags.
Combined with a wide range of validated standard designs, laser welding allows fast, reliable customization of any bag geometry, supporting both standard and highly specialized applications.
CertiFlex SAMPLIFY is designed for simple, reliable aseptic sampling.
Using advanced laser welding, each sampler is manufactured from a single continuous film (our “one-film” design).
This approach ensures:
Ideal for immediate deployment in aseptic bioprocess environments.

CertiFlex Safe-T Bags² are available in a patent-pending bag-in-bag configuration for applications involving high-value or highly potent products.
When handling bulk drug substances, ATMPs, or cytotoxic ADCs, the additional containment chamber provides enhanced safety.
In the event of a primary bag containment breach:




All CertiFlex single-use products are available RNase- and DNase-free, achieved through 3CON’s patent-pending non-thermal plasma process.
This ensures maximum suitability for sensitive biopharmaceutical applications and Advanced Therapeutic Medicinal Products (ATMP).
