Product Description
Empty Mini Columns: Mobicol Gravi – Clean-up by Gravity-Flow Chromatography. Column chromatography can be performed with automated systems which use a pump to force solvent over a packed column at a set flow rate, or can be run by gravity-flow. Mobicol Gravi columns are developed for performing size exclusion, affinity, or ion exchange chromatography by gravity-flow. By using the supplied Luer-lock cap, there is no limitation in volume, i.e., it is possible to apply small or large volumes of sample or buffer. Using the Luer-lock cap, a syringe can be connected to the top of the Mobicol Gravi column as a reservoir for sample or buffer. To enable a connection to larger reservoirs, an additional Luer-adapter is available to attach chromatography tubing to the top cap. This even enables a safe connection from a pump to the inlet of a Mobicol Gravi column. Luer connections for the bottom, a one-way stopcock and various filters are also offered to customize the columns to specific needs. Features: • Mini columns (up to 800 µl) for quick purification of biomolecules and other compounds • Fill with the matrix of your choice • Supplied with two different caps: screw cap with rubber seal and Luer-lock cap compatible to Luer syringes • Additional adapters for inlet and outlet chromatography tubing can be ordered separately • Plugs included for relocking • Filters of different sizes are offered to customize the columns to your specific needs • Autoclavable at 120 °C (with inserted filter at 110°C for 10 minutes) • Materials: polypropylene (column corpus), polyethylene (filters) • Available as Classic or Fixed type. Two types of Mobicol Gravi columns are available: Mobicol Gravi Classic and Mobicol Gravi Fixed. Both column types differ slightly in shape, but are totally equal regarding sample processing properties. The Classic variant has a separate and manually insertable plug for the outlet (bottom plug), whereas the Fixed type comes as one piece with a fixed snap-off plug. The Mobicol Gravi Fixed can be packed, stored, or shipped with no leakage. The outlet is 100% tight (even at varying pressures, e.g., transportation in airplanes) until bent off. The reverse side of the snap-off plug can then be used for relocking.
