HPLC Guard Column Poroshell SB 300 C18, 5 µm, 1 x 17 mm, 3 pc/pak

Poroshell StableBond 300 C18, guard column in 3-pack with inner diameter 1 mm, length 17 mm and particle size 5.0 µm. For use with hardware kit 820999-901 for the reversal phase with surface-porous particles. StableBond technology ensures stability at low pH.

SB-C18 and SB-C8 consist of voluminous silanes that sterically protect the siloxane bond. No acid-labile end-capping reagents are used. The result is a significantly longer column lifetime and exceptional chemical and thermal stability at pH 1-6. Lack of endcapping also results in a different selectivity than endcapped EC-C18 columns.
