Bio-Rad Laboratories, Inc. Econo-Column Chromatography Columns 737-4731

Pkg of 4, 0.7 x 30 cm, glass chromatography column, max. vol. 12 ml, cross-sectional area 0.39 cm2, for use in low-pressure chromatography Econo-Column chromatography columns are high-quality, low-pressure, glass chromatography columns. These highly versatile columns range in size from 5 to 170 cm long and 0.5 to 5.0 cm in diameter. A porous polymer bed support at the bottom of the column retains fine particles, and translucent polypropylene end fittings allow viewing of the entire column bed. Econo-Column chromatography columns are packaged in quantities of one, two, and four, depending on column diameter and length. All packages contain one stopcock per column ordered. Jacketed Econo-Column columns are glass Econo-Columns with an integral water jacket for cooling or heating. Jacketed columns are used in applications requiring temperature control. Features Features of Econo-Column chromatography columns include: Simple packing and procedure running Autoclavability and NaOH compatibility Operation at pressures <1 bar (14.7 psi) or in gravity flow applications Accessories Econo-Column funnels and reservoirs are used for packing columns, loading diluted samples, or delivering large volumes of buffer. Econo-Column flow adaptors improve column performance: they eliminate head space above the gel bed by protecting it from disruption during sample loading. Adaptors are used with 1.0, 1.5, 2.5, and 5.0 cm diameter columns. See the Econo-Column Chromatography Columns Selection Guide to select the appropriate column for your application.
