Columns

&microBondapak C18 columns are general purpose, silica-based, reversed-phase C18 columns that are based on 10 &microm particle technology. As a starting point for preparative chromatography, no other column can provide the balance between

Say goodbye to the limitations of traditional columns and experience greater speed, lasting durability and better results from your liquid chromatography instrument. Brownlee Superficially Porous Particle (SPP) columns produce sharper peaks and

Brownlee SPP 2.7 µm C18 2.1 X 50 mm

Brownlee SPP 2.7 µm C18 4.6 X 50 mm

Brownlee SPP 2.7 µm C8 3.0 X 100 mm

Features and Benefits Solid inner core, porous silica outer shell, shorter diffusion path Very high efficiencies at moderate back pressures   Nearly twice the efficiency of 3-µm particle columns As robust as columns packed with 5-µm particles because
