Small Drop Contact Angle Analyzer
The FTA4000 is a video drop shape analysis system optimized for extremely small drops. Both sessile drop contact angle and pendant drop surface tensions can be measured. Surface regions as small as 50 microns in diameter can be probed with drop volumes as low as 10 picoliters.

The unique NanoDispense electronic pump provides control for contact angle measurements for sessile drop volumes in from below 10 picoliters to many nanoliters. The entire instrument is enclosed to protect the measurement from air currents and rapid temperature changes. The design is clean room compatible.

  • Piezo-electric jetting for picoliter drops
  • Jetted volumes down to 20 picoliters
  • Can also form classical pendant drops up to ml volumes
  • Automated touch-off for classical drops
  • Dip-and-sip for low volume pump prime


Multi-Fluid Programmable Analyzer
The FTA2000 provides a high level of automation to characterizing surfaces of high value products such as silicon wafers, disk platters, and LCD panels. Contact angles, wetting tensions, and surface energy measurements can now be easily made over 2-D surfaces. The instrument makes point measurements on a grid covering the surface, then software computes a topographic map of the surface to assist in visualizing how the surface chemistry varies from one location to another

  • 300mm wafer capable platter, can handle smaller wafers
  • Can handle rectangular samples that fit within 300mm circle
  • Contact angle and surface tension analysis
  • Platter and camera tilt through 90° for receding angle analysis
  • 6 tip, 17 liquid vial, autosampler
  • Tip changer option available


Other models or configurations may be available. Please contact us with your application reqirements.
