This specific model features a 500 mm effective length and a 50 mm internal diameter. Includes a coarse porosity (40–60 µm) glass frit to support the stationary phase (packing material) without the need for glass wool. This is a standard large-format column suitable for high-volume liquid chromatography. It utilizes medium-wall tubing for added durability during pressurized flash chromatography. This column is ideal for flash chromatography techniques. The Contour Glass Chromatography Column is built from heavy-wall Borosilicate 3.3 glass, making it highly resistant to thermal shock and chemical attack from common chromatography solvents like hexane, ethyl acetate, and dichloromethane.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUsed, In good condition; the drip spout is chipped off below the stopcock.\u003c\/strong\u003e\u003c\/p\u003e","brand":"Contour Glass","offers":[{"title":"Default Title","offer_id":48656698671356,"sku":"10222","price":142.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8463\/5132\/files\/contour-glass-glass-chromatography-column-2942-upper-50-x-500-mm-with-fritted-disc-and-ptfe-stpk-chromatography-columns-reservoirs-contour-glass-922210.jpg?v=1767915078","url":"https:\/\/lifesciencestrading.com\/zh\/products\/contour-glass-glass-chromatography-column-29-42-upper-50-x-500-mm-with-fritted-disc-and-ptfe-stpk","provider":"Life Sciences Trading","version":"1.0","type":"link"}
