Malvern Panalytical - Molecular Size, stability and viscosity measurement - Viscosizer TD

Automating ultra-low volume Taylor Dispersion Analysis

Malvern Viscosizer TD is an automated biophysical characterization tool utilizing Taylor Dispersion Analysis and providing ultra-low volume, solution-based molecular size and stability measurement capabilities, combined with Poiseuille flow for relative viscosity assessment.

Viscosizer TD offers biopharmaceutical researchers an orthogonal technique for conformational stability analysis, which is unrivaled in extending into label-free measurements in highly complex solutions, and encompasses a critical size range from small molecules through to protein-based systems.
