Stericup^® E and Steritop^® E Filtration Systems

Millipore^® engineers innovate for your lab—and for our world

If you’re like us, you may have chosen a science career—at least in part—from a desire to make your world a better place. You might lead your group’s green lab practices from a sense of personal commitment to environmental responsibility, or seek solutions that help you meet institutional sustainability requirements. Either way, we have tools that can help you achieve your (official or honorary) green lab certification.

For more than six decades, Millipore^® minds have led the design and manufacture of membrane devices for the filtration needs of life scientists, enhancing and elevating sterile culture technique with the iconic Stericup^® and Steritop^® filtration devices. Our mission to develop trusted lab tools that are also environmentally responsible and sustainable has led to the design of the Stericup^® E and Steritop^® E filters, the newest—and most mindfully developed—members of our sterile filtration family.

How Stericup^® E and Steritop^® E filters reduce environmental impact—by the numbers

Reliable sterile filtration. Less plastic and packaging.

Our engineers found a device design that retains exceptional Stericup^® filtration while providing your lab a way to dramatically reduce the use of disposable plastic and packaging materials. Whether your goal is a green lab certification, or just a smaller footprint, both the Stericup^® E and Steritop^® E filters are designed to ensure trouble-free cell culture, while diminishing environmental impact in multiple ways.

How does Stericup^® E work?

Stericup^® E devices flip sterile filtration on its head—literally! We’ve eliminated the need for the plastic filler funnel by creating a way to attach standard media bottles or glassware directly onto the filter unit. Simply invert the Stericup^® E filter/receiver bottle assembly and thread onto the bottle containing media or buffer. Then, simply flip the assembly over, attach to vacuum, and watch sterile filtration happen. Steritop^® E saves even more plastic by allowing you to attach the filter to your own compatible, reusable labware receiver bottle before threading onto the bottle containing unfiltered media.

More labs choose Stericup^® filtration–here's why

Fastest media throughput for less clogging:

Comparison of media flow rate between multiple vacuum-driven filters. 500 mL of DMEM with 10% FBS was filtered through various vacuum-driven cup devices and timed.
