Traditionally, plaque and colony counting have been both slow and inefficient. It takes days, if not weeks, before plaques and colonies grow large enough to be seen using traditional methods. What’s more, they had to be grown within Petri dishes and other low-throughput plate formats, each of which had to be tediously counted by eye or separately loaded into a plate reader for analysis.

Not anymore, though! CTL BioSpot® Analyzers have been specifically optimized for scanning viral plaques and microbial and mammalian colony formation assays. They allow much smaller plaques and colonies to be detected, even against complex backgrounds, thus dramatically reducing the amount of growth time required. What’s more, because they support multiwell plate formats, they can also scan multiple samples in rapid succession.

Welcome to the future of microdetection.

 

BioSpot® Colony Counters

CTL-BioSpot® S6 UV Analyzer

CTL's cutting-edge instrument for both visible light and ultraviolet-enabled work. Do you have an application wherein you need to scan fluorescent bacterial colonies? Or do you simply want a versatile, high-performance instrument for both visible light and fluorescent assays? Either way, the BioSpot® S6 UV Analyzer is the model for you. The S6 UV Analyzer is designed to support both visible light assays (e.g. ELISPOT, colony counting) and fluorescence-based assays (e.g., FluoroSpot). It is also well suited for cell viability tests, apoptosis 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. The S6 UV also provides exceptional speed for single-cell analysis applications—generating results up to 120 times faster than flow cytometry, for example, when performing rare event analysis.

CTL-BioSpot® S6 Core Analyzer

The dedicated instrument for the sophisticated user. The S6 Core Analyzer is the instrument of choice for dedicated applications and specific plate formats.  The S6 Core can be outfitted with a manually adjustable zoom lens or it can be customized to provide fixed magnification for 6-, 12-, 24-, 96-, and 384-well plates. Its flexible illumination system can likewise be configured to produce optimal image results for a specific assay type.

CTL-BioSpot® S6 Macro Analyzer

The versatile instrument for scanning the widest range of plate formats.   When it comes to scanning multiple plate formats, nothing beats the S6 Macro.  Its advanced optical design allows it to scan 96-well plates, 100mm Petri dishes, and all formats in between (6-, 12-, and 24-well). Do you need to work with multiple plate formats? Then the versatility of the S6 Macro is just what you need!
