FLEX-COLUMN® an economical and easy-to-use
Short columns are typically used for ion exchange chromatography, sample desalting and semi-disposable applications, while the long columns are ideally suited for gel filtration and adsorption chromatography.
- Constructed of translucent polypropylene reservoirs and column outlets permanently connected to a borosilicate glass barrel, with removable polypropylene caps
- 20µm porosity High Density Polyethylene (HDPE) bed supports are fixed in the column outlets
- Tubing connections on the columns are male Luer locks
- A wide variety of adapters, valves, and fittings are available as accessories for use as simple and versatile tubing connections
- Available in 30 different sizes with standard inside diameters of 0.7, 1.0, 1.5 and 2.5cm and lengths ranging from 4 to 170cm
- Maximum pressure is 1.0 bar (14.7 psi, 1.0 atm, 0.1 MPa)
- Temperature range is 0 to 50°C
- Sterilize with 2N NaOH or 100% ethanol; autoclaving is not recommended
- Manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements
FLEX-COLUMN® Sample Diffusion Disc
- Sample diffusion discs protect the gel bed from being disrupted during sample application whenever a flow adapter is not used
- A transparent acrylic ring is sealed to a 20µm porosity HDPE disc which protects the top of the gel bed when the sample is manually applied
- A crossbar on the top of the acrylic ring permits easy removal of the sample diffusion disc from the column
