Fully compatible with the Shandon CytoSpin® Centrifuge, these CytoSep™ Cytology Funnels can be used to deposit a thin layer of cells in a clearly defined area of a microscope slide. The filter card absorbs any access fluid. They have the filter cards pre-attached for consistent, reliable results. No alignment necessary. All disposable funnels are packaged with closure caps to seal in specimen for added protection. All components are also available separately.
