Best for:
R&D teams, QA professionals and Educators who need a portable, multi-functional, and easy-to-use solution. Ideal for field work, labs with space constraints and academic settings
Use Case:
Perfect for institutions and teams seeking high measurement versatility (contact angle, surface energy, surface tension, sliding angle), smartphone-based portability, and cloud-enabled data sharing—all at a mid-range price.
Best for:
Academic labs and teaching environments with basic contact angle measurement needs and tight budgets.
Use Case:
A cost-effective option for performing simple, static contact angle measurements in educational or early-stage research labs, where advanced precision or automation is not required
Best for:
High-throughput industrial labs, regulatory environments, and advanced research centers needing automated precision and comprehensive measurement capabilities.
Use Case:
Suited for demanding applications in material development, QA/QC, and surface science R&D, where automated dosing, high-speed imaging, and advanced software analysis are essential—and budget and space are not constraints.
Providing accurate contact angle, surface tension, surface energy, and sliding angle measurements, Droplet Lab offers researchers and educators the technical capabilities normally found in far more expensive and cumbersome scientific equipment.
