    Transpiration Control Technology 

    About TCT

    Transpiration has been described in the scientific literature for years (e.g. Schumacher, 1958), and national metrological institutes such as NIST (National Institute of Standards and Technology) began discussing transpiration on certificates in the 1990s. Additionally, the packaging industry (among others) has published data regarding transpiration, though the effect is typically referred to as moisture vapor transmission rate (MVTR) or water vapor transmission rate (WVTR).

    After 20 years of data gathering and careful research, Inorganic Ventures is proud to unveil Transpiration Control Technology (TCT), a new packaging system that drastically extends the shelf life of their standard CRMs. 

    With TCT, concerns about shipping or storage conditions are eliminated, as transpiration is no longer an issue, which saves you money and simplifies research by removing the need to constantly inventory and restock CRMs.

    What is Transpiration?

    Transpiration refers to the passage of water vapor through the walls of a container and/or evaporation from the container opening. Transpiration results in an increase in the concentration of the CRM/RM.

    What is the solution?

    Transpiration Control Technology extends the shelf-life of the product. Inorganic Ventures uses a specially designed aluminized bag that prevents an increase in concentration of the CRM/RM until the TCT bag is opened.

    How it works!

    The cornerstone of the scientific community is accuracy. That’s why Inorganic Ventures has always been committed to producing the industry’s most exact Certified Reference Materials.

    But IV's control…and the control of every standard manufacturer…ends shortly after a standard is calibrated and packaged. IV are improving the way they deliver quality standards. The sealed TCT bag stops the loss of water vapor from the bottle when equilibrium is reached inside the bag.

    Has the product changed?

    The product has not changed, it is the same high-quality product you have come to depend on from Inorganic Ventures. It is the same but only better. TCT is an investment IV are making to extend shelf-life and give you more control at no extra charge. Inorganic Ventures products and unconditional guarantee remain the same.
