Product Description
Replacing just the glass barrel restores a removable-frit column setup without buying new adapters, clamps and discs. These barrels include the integral spherical reservoir, so eluent capacity stays the same as the original column. They are a cost-effective repair. Order the diameter that matches your setup.
This listing is for Kimble catalog number 422251-2520: KONTES Glass Column Barrel with Reservoir, 20 x 250 mm. Barrels are made from low-extractable 33 expansion borosilicate glass meeting USP Type I and ASTM E438, Type I, Class A, and each comes with one O-ring. They are 250 mm long with 12, 20 or 25 mm inside diameters. Transfer your stopcock adapter and fritted disc to complete the column. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
