The culmination of 20+ years in LC, Force performance LC columns are long-lasting and reproducible, even under the stress of UHPLC. Premium quality is backed by the strength of our 100% Pure Satisfaction guarantee. And perhaps most important, Force columns are fully scalable between 3 or 5 µm HPLC and 1.8 µm UHPLC, so you can easily transfer and optimize methods without extensive calculations. Apply Force LC columns to all of your HPLC and UHPLC instrument platforms.

The general-purpose Restek C18 is a conventional monomeric octadecylsilane column suitable for analyses of a wide range of compounds from acidic through slightly basic.
