Laboratory Supplies: Phthalate-Free Tubing in the News

Although we have referenced the benefits of phthalate-free tubing before, especially for food & beverage production, writer and Saint-Gobain Global Marketing Manager Iuliana Nita details the case once again in Whole Foods Magazine.

Specifically she states “Many tubing products are comprised of a fossil fuel-based phthalate called DEHP (di-2-ethylhexyl phthalate), which is a plasticizer used to give tubing its flexibility. Recent studies suggest DEHP may be responsible for negative environmental and human health impacts[1]. Already on the EU’s REACH candidate list of substances of very high concern (SVHC)[2] and California’s OEHHA Proposition 65 List of chemicals of concern[3], many industries, consumers and governments are putting limitations on the use of this chemical in certain applications. Adopting a non-DEHP, bio-based material solutions throughout the food and beverage production line will not only anticipate impending regulations on the chemical, but will also demonstrate their commitment to sustainability and foods safety to consumers and industry players.”

Cole-Parmer and Masterflex® partnered with Saint-Gobain to develop non-DEHP, phthalate- free tubing to withstand the rigors of peristaltic pump use. This collaboration resulted in the development of these tubing formulations for Masterflex:

Masterflex® Tygon® E-LFL (Long Flex Life) Pump Tubing

As the successor to Tygon® LFL, this new Tygon® E-LFL formulation offers the best peristaltic pump life of any clear Tygon tubing. It has been tested for up to 1,000 hours at 0 psi and 600 hours at 10 psi. This non-DEHP tubing is ideal for laboratory, food & beverage, and biopharmaceutical peristaltic pump applications. It can be sterilized via ethylene oxide gas (EtO) or autoclave. It meets USP Class VI, EP 3.2.9, ISO 10993, FDA criteria, NSF-51, and EU Food regulations.

Masterflex® Tygon® E-Food, Milk, and Dairy (B-44-4x) Tubing

This tubing is one of the first to offer a near global approval for the food, beverage, and sanitary industries. This non-DEHP formulation offers a significantly better pump life—second only to E-LFL for the clear Tygon formulations. Its smooth nonporous bore will not trap particles or promote bacterial growth. It is compatible with foods containing high oil content. It is also resistant to harsh cleaners, sanitizers, and can be sterilized via EtO and autoclave. This tubing meets FDA criteria, EU Food, 3-A, and NSF 51 and 61 standards.

Masterflex® Tygon® E-Lab (E-3603) Laboratory Tubing

The next generation of the successful Laboratory tubing (R-3603) combines high performing clarity, flexibility, and crack-resistance with affordability. Tygon® E-3606 Laboratory Tubing is designed for general laboratory work with peristaltic pumps and analytical instruments. It offers outstanding chemical compatibility, and can be sterilized by EtO and autoclave. Meets USP Class VI, NSF-51, FDA criteria, and EU Food regulations.

Masterflex® Tygon® Chemical (2001) Tubing

This tubing is compatible with aggressive chemicals, even MEK, and withstands acetone, DMSO, ketones, and more. It offers a cost-effective alternative to fluoropolymers or fluoroelastomers. Applications for this tubing include soap and detergent dispensing, water purification lines, chemical transfer, and more. Tygon® Chemical Tubing meets USP and FDA criteria for contact with food, beverages, and pharmaceuticals.

Tygon® E-1000 Ultra-Soft Non-DEHP Tubing

This tubing maintains flexibility even at low temperatures, making it perfect for synthesis and cryogenic applications. It is also appropriate for complex lab installations that require multiple directional changes, twisting, and abrupt curves. This tubing is FDA-compliant (21 CFR 175.300) and meets NSF 51 standards.
