Inside Our Flow Cytometers

  • ZE5 Cell Analyzer System Tour

    Designed by users for users – Watch this video to see how customer feedback directly resulted in the creation of an instrument that addresses gaps in other flow cytometer systems.

  • S3e Cell Sorter System Tour

    Taking the necessary steps to get data you can trust is integral to research breakthroughs. So we made sure you can get pure, viable cells for your downstream genomics experiments using the S3e™ Cell Sorter, an easy-to-use, high-speed fluorescence-activated cell sorting flow cytometer that fits right on your bench.

  • A Flow Cytometer Built for Automation and High throughput Screening

    Automated high throughput screening is enabled with ZE5 Cell Analyzer integrated into any robotic automation system such as Propel Labs’ Ascent and Biosero’s Green Button Go.

  • Developing the S3e Cell Sorter

    How do you reimagine a technology that's successful, accepted, and already in relatively widespread use? If the technology in question is cell sorting, you "think outside the box" by designing to "fit inside the box.“ Watch this video to see how some of the design innovations in the S3e Cell Sorter came about, including a more accurate way of calculating drop delay not found in any other benchtop flow cytometer.
