US-based Entegris has unveiled its new Aramus 2D bag assembly for single-use bioprocessing applications.

The new Aramus assemblies are available in 500ml, 1l and 2l sizes, and use improved film technology that is comprised of one fluoropolymer, gamma-stable film in a single layer.

The new film provides an increased level of protection from particles and removes common extractables from conventional single-use bags that can leach into bioprocessing fluids.

Claimed to be the first of a future suite of single-use products of Entegris’ Aramus brand, the new bag features associated clamps, tubing and fittings that complete the assembly.

Produced in an ISO Class 5 clean room, Aramus single-use assemblies are said to provide enhanced compatibility and easier validation.

The Entegris fluoropolymer technology used in the assembly also provides benefits, including increased efficacy in frozen applications to reduce the risk of assembly breakage.

Entegris life sciences director Eric Isberg said: "Entegris has a long history of providing advanced, polymer-based technologies for leading-edge processes that have stringent quality standards and contamination controls.

"This served us well in developing a single, strong bioprocessing film that maintains gamma stability.

"Our new Aramus bag assembly provides a new level of purity and protection for final filling."

"Our new Aramus bag assembly leverages that history and expertise, and provides a new level of purity and protection for final filling with the flexibility for use in a wide variety of other bioprocessing applications."

The company noted that advanced bioprocessing applications rely on single-use technologies to effectively meet cost and batch-size requirements in bioprocessing.

The bags need to maintain the purity of bioprocess materials throughout a variety of temperatures and uses, handling and transportation.

Entegris provides advanced manufacturing processes in the semiconductor, life sciences and other high-technology industries.

The company has manufacturing, customer service and / or research facilities in the US, China, France, Germany, Israel, Japan, Malaysia, Singapore, South Korea and Taiwan.
