Stericup® E & Steritop® E Sterile Filters by Merck: Sustainable Sterile Filtration for Cell Culture

Laboratories seek reliable sterile filtration without the burden of excessive plastic waste. Stericup® E and Steritop® E sterile filters by Merck are engineered with sustainability at their core, reducing plastic by up to 48% while maintaining the trusted performance cell cultures demand. Learn how these innovative filters meet environmental goals and industry standards for superior sterile media filtration.

Why choose Stericup® E and Steritop® E sterile filters

• Trusted sterile filtration performance: Provides the same reliable sterile filtration performance trusted for decades.
• Cell culture suitability: Provides dependable sterile filtration specifically optimized for cell culture workflows.
• Lower plastic waste: Reduces disposable plastic waste by 23% to 48%, depending on the product version.
• Less packaging waste: Reduces packaging by 11% to 69%, depending on the product version.
• Support for sustainability goals: Helps laboratories reduce disposable plastic and packaging materials in line with institutional sustainability objectives.
• Reduced storage needs: The compact design can reduce the volume of product boxes by 26% to 73%, requiring less storage space.
• Lower shipping impact: The more lightweight design requires less fuel for shipping, resulting in reduced greenhouse gas emissions.
• Less biohazardous waste: Significantly reduces the amount of biohazardous waste along with the associated treatment and disposal costs.

Key features and design

• Design architecture: Stericup® E and Steritop® E sterile filters were developed using Design for Sustainability principles as eco-friendly additions to the Stericup® family.
• Direct bottle connection: The devices eliminate the plastic filter funnel by threading directly onto the media bottle.
• Thread compatibility: Two diameters of threaded couplings were developed to fit the two most common commercial bottle formats.
• Stericup® E workflow mechanism: Stericup® E devices use an inverted filter and receiver bottle assembly that threads onto the media or buffer bottle, then is flipped over and connected to vacuum for filtration.
• Steritop® E configuration: Steritop® E devices first attach to a compatible reusable receiver bottle, and this assembly is then threaded onto the media bottle.
• System format: Stericup® E is a complete sterile filtration unit with an integrated receiver bottle, while Steritop® E is a threaded bottle-top filter designed for use with separate reusable receiver bottles.
• Packaging design elements: The packaging was developed in alignment with the SMASH Packaging initiative and uses boxes and inserts with sustainable forestry certification and polyethylene plastic pouches.
• Documentation format: The product user guide and certificate of quality are provided in electronic versions instead of printed documents placed in the product box.

Technical specifications

• Pore size: .22 μm 
• Thread sizes: 38 mm and 45 mm
• Product volume: 500 mL and 1000 mL

Applications and basic use

• Sterile filtration of media and buffers: Designed for reliable sterile filtration of a wide range of cell culture media and buffers.
• Cell culture suitability: Suitable for routine cell culture media and buffer preparation in research and production laboratories.
• Stericup® E basic use: The device threads directly onto a commercial media or buffer bottle, the filter and receiver bottle assembly is inverted to thread onto the bottle, and the assembly is then flipped over to connect to vacuum for filtration.
• Steritop® E basic use: The filter attaches to a compatible, reusable labware receiver bottle before it is threaded onto the media bottle for sterile filtration.
