The Simport 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, and bronchial secretions. They come in four sizes from 1mL to 8mL. The 1mL chamber is for small-volume samples of low cell contents. Both 2 and 4mL chambers are suggested for cell-rich samples, e.g. pleura, ascites and bronchial washings while the 8mL chamber is perfect for large-volume samples such as urine.
