Liquid chromatography columns

Luer Lock, Non-jacketed, bed volume 18 mL, I.D. × L 1.5 cm × 10 cm

Description

General description

All of the columns listed below are constructed of borosilicate glass. Four different fixed bed length configurations are available:
• Luer Lock, non-jacketed: constructed with fixed polypropylene end caps, polyethylene bed supports, and Luer Lock inlet and outlet fittings. The Luer Lock connections on these columns are male. The polyethylene bed support has a nominal pore size of 20 μm.
• Open-ended: constructed with fixed polypropylene ends, without jacket or end fittings. Requires at least one flow adapter (see Accessories)
• PTFE, non-jacketed: constructed with threaded ends. Removable PTFE fittings with shielded O-ring seals, 20 μm polyethylene bed support, and 1/4-28 threaded tubing connections provided. Columns come with O-ring seals, bed support and tubing connections.
• PTFE, jacketed: same as above with an acrylic jacket surrounding the column body for temperature control.
Columns come with O-ring seals, bed support and tubing connections.
The glass and polypropylene portions of these columns are autoclavable, but the polyethylene bed supports are not autoclavable. This renders sterilization impossible. One can try a 2 N sodium hydroxide wash or methyl/ethyl alcohol washes on the assembled column to try to get as close to sterile as possible. Harsher organic solvents such as chloroform or toluene are not recommended.
