Precision Microneedle Coating with BIOSPOT® DX

Microneedle patches are transforming transdermal drug and vaccine delivery thanks to their minimal invasiveness, ease of use, and dose accuracy. Yet, reliably coating microneedles with consistent droplet volumes remains a major manufacturing challenge. The BIOSPOT® DX enables precise, contact-free droplet deposition directly on the microneedle tip—ensuring stable, reproducible coating results for any patch design.

Engineered for Accuracy and Throughput

  • Precise: Drop-on-demand PIPEJET® dispensing delivers nanoliter-sized droplets with CV <1%, even for viscous formulations.
  • Customizable: TOPVIEW-guided targeting allows for individual spotting patterns per patch, compensating for geometry tolerances.
  • Effortless: The fully automated workflow integrates SMARTDROP® calibration, needle detection, and quality control for fast, hands-free operation.
