Core Enhanced TechnologyTM

Solid Core Particles – 2.6µm diameter particles with a solid core generate high speed, high resolution separations without excessive backpressure

Advanced Bonding Technology – Optimised phase bonding creates a series of high coverage, robust phases

Tight Control of Particle Diameter – Enhanced selection process keeps particle size distribution to a minimum and produces high efficiency columns

Automated Packing Process -Enhanced automated procedures ensure that all columns are packed with the highest quality
