ClickTek technologies were created with the user’s point of view in mind, to simplify the troublesome process of replacing consumables. Just a single touch is needed to open the injection port and connect the column, making the liner and column replacement simple and easy. They also eliminate the risk of over-tightening or under-tightening the nuts, which could lead to damaged nuts or air-leaks. They were introduced with Nexis GC-2030 and are also available for GC-2010 (Plus) and GC-2025 series. The ClickTek ferrules can be used up to 350 °C.
