Live Cell Research Time-lapse live cell imaging system

WSL-1800 CytoWatcher is a compact digital microscope.

No stress to take space in laboratory and moisture resistant for setting in a COincubator for time-lapse live cell imaging.

WSL-1800 CytoWatcher
Purpose and Application

> For bright field cell imaging with low magnification.

> Compact size, no stress to take space.

> Usable in CO2 incubator, for time-lapse imaging in culture condition.

> Equipped with 5M pixels color CMOS camera.

> Multiple samples can be taken by connecting multiple units.

> A model for fluorescent imaging has appeared.

Product Summary

WSL-1800 CytoWatcher is a digital microscope equipped with a 5 megapixel color CMOS camera.

By simply connecting to a Windows PC with a USB cable, you can capture and save microscopic images with a simple operation.

Since CytoWatcher is moisture-proof, it can be placed in a CO2 incubator to take time-lapse images automatically while culturing cells.

Usable in CO2 incubator

Since CytoWatcher body is moisture-proof, it can take time-lapsed images of live cells with cultured in a high humidity CO2 incubator. There is no need to use an expensive microscope stage culture system.





Compact microscope

As CytoWatcher is compact, it can be used in a limited space such as a labolatory bench or a safety cabinet. As it is easy to carry, you can take it to your work space and use it.



Just connect to PC with USB

CytoWatcher is used by connecting it to a Windows PC (option) with a USB 3.0 cable (power is supplied from the PC via USB). If you start the control software ImageSaverT (included as standard), you can see live cell images immediately. You can also save images and take time-lapse images easily.



Multiple units can be controlled by one PC

Multiple CytoWatchers can be connected to one PC and used (up to 4 units) for simultaneous time-lapse imaging of multiple samples in parallel.



Fluorescent imaging

The fluorescent imaging model is equipped with a blue LED light source and an excitation / emission filter, and supports green emitted fluorescent imaging such as GFP. It is possible to set it up in a CO2 incubator and combine it with bright field and fluorescent time-lapse imaging.
