Bio-Rad offers a range of chromatography columns and accessories to accommodate your needs. Products include empty spin columns, low-pressure columns with optimal flow adaptors and jackets for temperature control, and analytical columns for medium- or high-pressure systems.
Poly-Prep columns are 9 cm–high 0.8 x 4 cm conical polypropylene columns that hold up to 2 ml chromatography medium and 10 ml eluent or sample. Ideal for desalting, sample preparation, and other small-scale teaching lab applications, Poly-Prep columns can be autoclaved before or after use, will retain fine support particles, and are reusable.
Econo-Pac columns are 14 cm–high 1.5 x 12 cm polypropylene columns that can be fitted with a flow adaptor or used for gravity-flow chromatography. When used for open-column work, a special upper bed support prevents the bed from running dry. Bed volumes from 1 to 20 ml are acceptable. These columns can be autoclaved and will retain fine particles.
Glass Econo-Column Columns
Econo-Column columns are high-quality, affordable, low-pressure chromatography columns. Bio-Rad offers columns ranging from 5 to 170 cm in length and 0.5 to 5 cm in diameter. These columns will retain fine particles and can be autoclaved.
Bio-Spin and Micro Bio-Spin Columns
Empty Bio-Spin and Micro Bio-Spin chromatography columns are disposable polypropylene spin columns that can be packed with a variety of chromatographic media. Bio-Spin columns hold up to 1.1 ml medium and fit in standard swinging bucket centrifuges. Micro Bio-Spin columns hold up to 0.8 ml medium and fit in all standard microcentrifuges. Both columns fit standard micro test tubes, have snap-off tips and polyethylene bed supports, and are autoclavable.
