New Cool-Lock™ Nut Ensures Precise and Painless GC Column Installation

Phenomenex Inc., a leading worldwide manufacturer of separation science consumables, introduces the Cool-Lock Nut, a unique device (patent pending) that simplifies GC column installation and eliminates the need for wrenches or other tools. The low thermal mass design allows the Cool-Lock Nut to cool rapidly, preventing users from burning their fingers during column changes. Other unique design elements prevent the column from slipping to ensure a more reproducible installation depth for improved method accuracy.

“80 to 90 percent of all GC column problems originate in the injection port because installation has always been so challenging. It’s difficult to ensure exact positioning because the work space is cramped and the materials are quite hot,” explained Ngoc Nguyen, brand manager for Phenomenex. “This new device allows users to change a column very quickly without tools and without burning their fingers.”

The Phenomenex Cool-Lock Nut is designed for use with Agilent Technologies^® GC instruments and works with all standard GC columns. The nut is available in both long and short ferrule style dimensions and can be used over and over for accurate column installations.
