EVE™ PLUS Automatic Cell Counter – Witec AG

EVE™ PLUS, a compact image-based automated cell counter, uses disposable slides to most accurately determine eukaryotic cell titers in less than 1 second.

In addition, when applying trypan blue staining, the system will discriminate live from dead cells precisely to provide reliable data on cell viability. Compared to counting cells manually using classical haemocytometers the EVE™ PLUS automated cell counter offers three main benefits:

• Reproducible, objective data, free from human bias/error
• Quick and lean workflow saves time and increases productivity
• Disposable counting slides improve lab safety

The EVE™ PLUS uses advanced optics and image analysis algorithms for counting even challenging clumped cell populations at a precision that is proven to be comparable to more complex fluorescence-based counting methods.

The cell concentration measuring range is 2 x 10⁷ cells/ml with cell sizes ranging from 5 to 60 µm being recognised. The system can therefore be used on all kinds of round-shaped mammalian cell lines, primary cells, red blood cells, PBMC and some round types of yeast. For irregular shaped cells we recommend the fluorescence-based cell counter ADAM MC2.

Key features & benefits

• Count less than 1 second
• Manual and Auto focus function
• Count aggregated cells individually
• Trypan blue staining method
• Easy to use

A well-arranged touch screen user interface together with smart data storage and transfer options guarantee for easy and hassle-free operation.

The EVE™ PLUS uses the EVE™ cell counting slides which offer reproducible and reliable measurements and analysis. The unique design eliminates the use of cover slips and allows for exact volume control (10 µl cell suspension per test). In contrast to classical haemocytometers the disposable slides reduce the user's risk of exposure to biological samples and eliminate the need for washing or autoclaving components. Each slide contains two enclosed chambers allowing for two tests per slide.
