Benchmark chromatography columns

BenchMark™ columns are designed to suit the majority of standard laboratory chromatography applications. They are ideal for aqueous systems and compatible with solvents used in common liquid chromatography applications such as protein purification. Economical modular columns for low pressure or gravity feed, providing even distribution of eluent to the medium bed, with or without flow adapters.Available in seven diameters and a variety of lengths. Compatible with a variety of bulk media.
