CTL's cutting-edge instrument for both visible light and ultraviolet-enabled work.
The S5 UV Analyzer is CTL’s top-of-the-line model, being designed to support both visible light assays (e.g. ELISPOT, colony counting) and fluorescence-based FluoroSpot assays. It is also well suited for cell viability tests, apotosis tests and in vivo/in vitro cytotoxicity measurements using cells labeled with fluorescent dyes. Its mechanical design allows users to readily switch back and forth between the visible light and fluorescent modes, and its multi-filter design allows users to take advantage of the entire fluorescence-based spectrum.

CTL’s high-resolution model for microscopic analysis.
The S5 Micro’s zoom lens permits seamless switching between 24-, 48-, and 96-well plate formats. Its advanced optics allow users to zoom in further for more precise detail. Even individual stained cells as small as 10 µm in diameter can be detected.

The versatile instrument for scanning the widest range of plate formats. When it comes to scanning multiple plate formats, nothing beats the S5 Macro. Its advanced optical design allows it to scan formats that range from 96-well plates to 100mm Petri dishes. When you need a versatile instrument that can analyze ELISPOT plates as well as many classical assays (bacterial, yeast, stem cell, and tumor colonies, as well as clonogenic and viral plaque assays), then the S5 Macro is the choice for you!
