Cellwatcher S
Your eye on your cell cultures
The first choice for quality control in cell culture: Cellwatcher S. Built for non-invasive measurements inside your incubator, Cellwatcher S is the world's most compact microscope system, offering high integration density for scalable monitoring. Tailored to your workflows in every respect, from installation to cleaning and your daily cell culture tasks, Cellwatcher S keeps an eye on your cells.
Cells grow most stably in constant environments, which is why we keep them in incubators: but every manual monitoring step, like opening incubators, handling dishes, removing and imaging cells, changes this environment, increases the risks of contamination, and can permanently alter the cell behavior. By monitoring inside the incubator, Cellwatcher S ensures a perfectly constant environment and high cell quality.

Get the data to know your cells better.

Standardize your cell culture: establish your own protocols based on objective quantification, passage after passage. The Cellwatcher S supports you by monitoring and documenting the most important cell parameters: growth, motility, seeding/splitting confluency, phenotypic changes, and many more. This enables you to detect abnormalities in your cell culture early, before bringing them into assays, saving you time and consumables. Variations in cell performance belong to the past.
