Description
Christopher Herz and colleagues describe a 2026 laboratory study that designs and tests a reusable funnel for cytospin work, the method labs use to fix cells from body fluids onto microscope slides. Commercial funnels are mostly single use, costly, and limited to a small slide area. The team set out to print a cheaper funnel that covers a larger area.
Working with design software and a printer that builds parts from a medical resin, they shaped prototypes to fit a standard cytocentrifuge. Tests used two human pleural fluid samples, meaning fluid taken from around the lungs, across a wide range of cell counts. The printed funnel roughly tripled the cytospin area, raised how many cells could be loaded, and survived repeated cleaning with two common disinfectants. Because the design file is published, other labs can print and adapt it, which may help places with tight budgets.
