HEL process crystallisation systems provide solubility data and/or Particle-Size Distribution. Solubility and MSZW data may be obtained from single or parallel platforms and in scale from 1 to 500mL. Clever automation replaces dozens of manual experiments with a single run.

Particle studies are delivered by PAT devices such as Laser Particle-Sizers and turbidity monitoring systems - integrated directly into the software for real-time process monitoring, control and particle size distribution analysis.


CrystalSCAN // Automated Crystallisation Screening system
CrystalSCAN // Automated Crystallisation Screening system

The CrystalSCAN is a versatile automated platform for determining Solubility and Meta-Stable Zone Width (MSZW), in multiple, parallel samples. With precise temperature-control and integrated dilution pumps, the system allows for the investigation over a wide concentration and temperature range.

Subsieve AutoSizer // Automated Fisher Number (FSSS) Particle-Sizing System

A complete update on a venerable workhorse, the SAS supercedes the Fisher Sub-Sieve Sizer (FSSS), widely used in many industries as a critical particle-sizing QC tool. The SAS employs modern electromechanics and a simple touchscreen interface to bring Fisher number (air-permeability particle sizing) measurements into the 21st century.
