Product Description
Preparative separations scale more easily when columns connect directly to reservoirs and flow adapters through a standard joint. These glass columns have a standard taper top joint and PTFE stopcock, giving you a modular system for gravity and low-pressure work across a wide span of sizes.
This listing is for Kimble catalog number 420510-0250: KONTES Glass Chromatography Column, 19 mmm ID, 76 mL. Columns are made from borosilicate glass 3.3, with 24/40 or 45/50 top joints and 2 or 4 mm stopcock bores. Inner diameters range from 13 to 75 mm and lengths from 200 to 600 mm. Glass wool, not supplied, can support the packing. Use them alone or with 420570 series reservoirs and 420575 series flow control adapters. LIGHT LABS ships genuine DWK Life Sciences products with knowledgeable support from our Englewood, Colorado team.
