Hudson Rapid pH PLUS
Single and 4 Probe system
Automated 96 plate pH
The Rapid_pH™ benchtop pH meter reduces the time and tedium associated with manual pH testing. Manual use of Laboratory pH meters typically requires endless rinsing, drying, immersing, waiting for stabilization and recording of the result. The Rapid_pH automated pH meter makes your life so much easier by completely automating all of these steps at the press of a single click.
Replace hours of manual pH measurement with minutes of setup and automated plate-based workflows. Set up your plate, press start, and walk away.
Rapid pH Plus is an automated, plate-based system powered by intuitive software that enables reproducible, searchable data generation for high-throughput formulation and buffer optimization workflows.
Configurable hardware supports single- or 4-probe capacity, with optional Power Wash, enabling scalable performance across diverse biologics development workflows
