The HoloMonitor Hardware

Base unit of the HoloMonitor cell culture microscope

Imaging Unit

The base unit is the actual microscope, placed in your incubator and responsible for continuously imaging your live cell cultures.

HoloMonitor base unit with the motorized stage quantitative cell imaging

Motorized Stage

The motorized stage supports a variety of culture vessels. Further on, it enables automated and continuous imaging of multiple positions in your sample.

The laser unit of the HoloMonitor live cell imaging system

Laser Unit

The laser unit is placed outside your incubator and provides a low-energy laser to enable holographic imaging without affecting your cells.

The HoloMonitor Software

The heart of HoloMonitor is the modular App Suite software, with tailor-made apps for different live cell assays. Each app offers a guided setup of your experiment, automatic image collection and real-time data analysis and presentation.

Moreover, HoloMonitor App Suite excels when it comes to data reanalysis. Every experiment contains all data necessary to reanalyze it as another type of experiment. For example, a proliferation assay can be reanalyzed as a motility assay at a later point. Hence, no need to spend time, money and cells on a new experiment!

HoloMonitor Live Cell Assays

The Workflow

Designed by cell biologists, the HoloMonitor App Suite software offers a simple and guided user interface. So, with a self-explanatory workflow, it guides you from experiment setup to data presentation in 5 simple steps:

  1. Assay selection
  2. Basic setup
  3. Image capture setup
  4. Start capturing images
  5. View the results in real-time

HoloMonitor Accessories

24-well HoloLid and plate mounted on plate holder

Culture Vessel Holders

HoloMonitor’s motorized stage supports a variety of culture vessels, each secured with a vessel holder. This means easy attachment and exact positioning on the microscope.
