FIT screening

The FIT-based screening test is easy and therefore manages to attract high participation rates – the main driver behind the success of any national or regional screening programme. Generally, national or regional administrations assume responsibility for managing the logistics, financials and efficiency of the programme in close cooperation with their selected laboratory partners.

For reliable, repeatable and rapid results

The Viscotek RImax is a complete, GPC/SEC system suitable for the relative molecular weight characterization of proteins, natural and synthetic polymers, copolymers and other macromolecules.

The RImax is a modular system consisting of the GPCmax integrated solvent and sample delivery module, refractive index detector, column oven, plus the same powerful OmniSEC software used in the TDAmax research system.
