HPLC Guard Cartridge Ultra Silica, 100Å, 5 µm, 10 x 4.0 mm, 3 pc/PAK

Note: We strongly recommend that you only order a semi-preparative or preparative column once you have evaluated the desired separation on an equivalent column on an analytical scale.
Because we cannot reuse a column or the silica within it once it leaves our facility, we cannot accept returns of large columns.
