Merck Launches Ultimus® Film to Offer Superior Strength and Leak Resistance in Single-use Assemblies

publication date: May 25, 2023
author/source: Merck



Supports healthy cell growth and improves operational efficiency

Merck has announced the launch of its Ultimus® Single-Use Process Container Film, designed to provide extreme durability and leak resistance for single use assemblies used for bioprocessing liquid applications.

Bag leaks have long been a top pain point for biomanufacturers, with the cost of a single leak ranging from € 45,000 to € 511,000. To protect against such leaks, abrasions, tears, and material fatigue, Ultimus® film is designed with a proprietary woven nylon structure and provides enhanced bag strength, improved durability, and resilience.

"We are committed to providing our customers with solutions that address their challenges in single-use manufacturing," said Darren Verlenden, Head of Process Solutions for the Life Science business sector of Merck. "Our innovative approach of incorporating woven nylon ensures the film’s robustness while providing ease of handling, flexibility, and conformity to a container that single-use processing demands.”

Maintaining the film's integrity is crucial to ensure product quality, sterility, and reliable manufacturing operations in single-use bioprocessing. To achieve this, Ultimus® film has undergone rigorous testing and demonstrated exceptional performance compared to the average results of five other single-use bioprocessing films. This includes 10 times greater abrasion resistance, 2.8 times greater tensile strength, and twice as much puncture strength.

Ultimus® film provides an animal origin free contact resin that demonstrates a low extractable profile and supports healthy cell growth performance. This cutting-edge technology is now available in Mobius®3D process containers, delivering a stronger and more durable solution that improves operational efficiency while minimizing disruptions.
