Graphite Capillary Column Ferrules - 0.125 in Nut x 0.5 mm I.D., Pkg. 10

Of the three ferrule types available, graphite is the softest, making it less damaging to capillary columns when overtightened. Graphite seals easily and does not stick to glass columns. These one-piece ferrules do not require rear ferrules.
