Blueprint: Hand-Powered Centrifuge for Blood Separation — Build and Implementation Specification
Year: 2026
Type: article
Abstract: Build and implementation specification for a hand-cranked centrifuge for blood separation where there is no power: a skeleton cross-arm aluminium rotor of 130 mm outer radius carrying 24 capillary tubes, driven at 8,000 rpm through a 100:1 compound drive at a crank cadence of 80 rpm, delivering 6,797 g at the tube midpoint, a specified 9 min hematocrit spin and 11 min malaria concentration spin, and 48 patients per hour in duplicate, with bill of materials, dimensions and construction, assembly, operating procedure, operating envelope, tolerances, failure modes, maintenance, safety limits, and costs. DESIGN BLUEPRINT — SIMULATED, NOT MEASURED — NOT BUILT, NOT CLINICALLY TESTED. Blueprint for the design published as DOI 10.5281/zenodo.24109222.
