The CytoSep™ Funnel Chambers for the Hettich Cyto-System optimize lab throughput with multiple funnel options in 2, 3 or 4 funnels per slide. These funnels are perfect for every application such as CSF, Viral infections, Bronchial secretions and come in four sizes from 1 ml to 8 ml. The 1 ml chamber is for small-volume samples of low cell contents. Both 2 and 4 ml chambers are suggested for cell-rich samples, e.g. pleura, ascites and bronchial washing while the 8 ml chamber is perfect for large volume samples such as urine.
