Fully compatible with the Shandon CytoSpin Centrifuge, these funnels can be used to deposit a thin layer of cells in a clearly defined area of a microscope slide. An integrated filter card absorbs any excess fluid. Easy-to-follow instructions are included in each pack. Stainless steel clips, which hold the Cytology Funnels securely in place against the microscope slide during the centrifugation process, are also available. The clips will not rust during decontamination.
