Stericup® E and
Steritop® E Sterile Filters


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. Whatever motivates you, 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 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. First, 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 devices save 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.


Stericup® E filters reduce plastic waste up to 26% and packaging waste up to 20%, while Steritop® E filters reduce plastic waste up to 48% and packaging waste up to 69%.

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.

Usage Guidelines

Choose a collar thread (38 mm or 45 mm) that is compatible with your glass or plastic media/ buffer bottle.

  • The 38 mm thread is recommended for Merck media bottles and majority of other standard commercial media bottles.
  • The 45 mm thread is recommended for wider neck media bottles (such as Gibco®).
  • Use only glass or plastic bottles designed for vacuum applications. For the Steritop® E filter funnel, use a 45 mm threaded glass or plastic receiver bottle no larger than 2 liters.


STERICUP® E AND STERITOP® E FILTER UNITS – SUSTAINABILITY CHECKLIST

  • Stericup® E and Steritop® E filters thread directly onto any commercial media bottle or glass bottle:
    • Reduces plastic and hazardous waste.
    • Frees-up storage in labs—crucial in smaller tissue culture rooms, where space is at a premium.
    • Enhances laboratory compliance with institutional sustainability requirements—or a means for achieving individual environmental responsibility goals.
  • Stericup® E and Steritop® E filters have the Accountability, Consistency, and Transparency (ACT) Environmental Impact Factor Label, published by My Green Lab®, providing a score based around manufacturing processes, energy and water use, packaging and end-of-life. The ACT labelled products help labs choose greener life science products. ACT labels can be viewed for each Stericup® E and Steritop® E product by visiting the product pages via the table below.
  • Stericup® E and Steritop® E filters are packaged in individual, recyclable pouches for sterility.
  • Stericup® E and Steritop® E filter user guides are provided in digital format, accessible here on our website, or via scanning the QR code on the packaging label, to reduce paper waste.
  • The Stericup® E and Steritop® E corrugated boxes and dividers have sustainable forestry certification.
