Product Description
An integral reservoir holds plenty of eluent above the bed, so you can run longer separations without constant topping up. These basic glass columns combine that reservoir with a PTFE stopcock for steady, controllable flow. They suit both research and teaching labs.
This listing is for Kimble catalog number 420280-0232: Basic Glass Chromatography Column, 19 mm. Columns are made from borosilicate glass 3.3, and the top is tooled to accept a rubber stopper. A size 2 PTFE stopcock plug controls flow, and a glass wool plug can support the packing. Inner diameters run from 11 to 30 mm with column lengths from 250 to 400 mm. LIGHT LABS ships genuine DWK Life Sciences products with knowledgeable support from our Englewood, Colorado team.
