Michrom Peek Isolation Tube 20 um 200 x 50 Column

The Michrom PEEK Isolation Tube (20 µm, 200 x 50 mm) is a high-performance chromatography component designed to serve as a sacrificial guard or isolation stage for analytical HPLC columns. Manufactured from Polyetheretherketone (PEEK), this housing is entirely metal-free and biocompatible, making it the preferred choice for proteomic and biopharmaceutical applications where sensitive samples could be denatured or "chelated" by contact with stainless steel. The PEEK construction provides exceptional chemical resistance across nearly the entire pH range and can handle the high-pressure demands of modern liquid chromatography systems.

This specific model features a 20 µm porosity internal filtration element, which is a slightly coarser grade compared to standard 10 µm units. This higher porosity is specifically selected to manage "dirtier" or more viscous samples, allowing for a higher dirt-loading capacity before the system experiences a significant increase in backpressure. With dimensions of 200 mm in length and a 50 mm diameter, this isolation tube is designed for large-scale preparative or semi-prep chromatography rather than standard analytical microbore work. By capturing particulates and irreversibly bound contaminants in this large-volume isolation zone, the unit prevents the fouling of the primary stationary phase, thereby maintaining peak symmetry and extending the operational life of the main column. This is particularly vital in Michrom (Bruker) systems used for large-volume sample preparation in mass spectrometry workflows.
