The iLine F from Ovizio Imaging Systems is an in-line suspension cell-monitoring microscope that uses a quantitative imaging technique based on differential digital holographic microscopy. Distributed by Applikon Biotechnology, Foster City, Calif, the microscope monitors cell viability and cell density in real time, and records aggregate data with up to 16 morphologic parameters. Automated technology offers increased insight into the cell culture process by continuously collecting quantitative data, providing reproducible, reliable results. The label-free, noninvasive unit does not require sampling or staining, or produce toxic waste. It is connected to a bioreactor via a disposable fluidics probe, avoiding sample consumption and reducing the risk of contamination. The microscope is compliant with good manufacturing practices.
