With 30 years of chromatography and light scattering experience, the Viscotek GPC/SEC systems and detectors from Malvern provide solutions for all applications of proteins, synthetic and natural polymers. Complete systems are available as out-of-the-box solutions for macromolecular characterization. Alternatively, upgrade an existing system through the addition of a modular detector. The entire Viscotek range is backed by the Malvern’s global support and training network.

Viscotek Systems - Out-of-the-box Solutions for the Characterization of Proteins, Synthetic and Natural Polymers

The Viscotek range provides a choice of integrated or modular GPC / SEC systems for the analysis of the molecular weight, molecular weight distribution, molecular size and structure of proteins, synthetic and natural polymers.
 

Viscotek Detectors - A Comprehensive Range of Advanced GPC/SEC Detectors

The Viscotek advanced GPC/SEC detectors can be used to upgrade any existing system to triple detection to add the power of light scattering (low angle or right angle) or multi-angle light scattering (SEC-MALS) to measure absolute molecular weight, or a viscometer to measure intrinsic viscosity. Concentration detectors such as refractive index and UV are also available.
