Our engineers innovate for your lab—and for our world

For more than six decades, Merck® 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 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 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.

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.
