Introducing the MELISA MP-MED v1, a twelve-plate microdroplet dispenser engineered for high-throughput and ultra-precise deposition. This video presents two continuous, unedited workflow demonstrations:

3-plex automated printing: High-speed deposition of three different reagents in a 3×5 grid across multiple plate positions, with integrated wash and liquid-change steps.

High-consistency 6×6 matrix: Uniform microdot array with spots <150 μm in diameter and ≤500 pL in volume, highlighting reproducibility and precision.
