YMC Pilot Columns

Pilot columns are designed for use in pilot and production scale applications with organic solvents (SR version) or aqueous buffers (AB version), which makes them suitable for all common methods in chromatography including normal phase, reversed phase or biochromatography. High precision CNC manufacturing of plungers and distribution plates provides outstanding flow distribution for a linear flow distribution profile. Precise and reliable bed height adjustment can be achieved by hand wheel adjusters on the plunger. The variety of mounting options includes a fixed stand, wheeled trolley, or direct attachment to plant. All materials are in compliance with FDA regulations; certification and full documentation are available for validation purposes on request.
