Solvent Inlet Filters, Inline Filters, Precolumn Filters, and Frits
Chrom Tech supplies a full range of HPLC solvent and inline filters engineered to maintain clean mobile-phase flow and extend column life. From standard and bottom-of-bottle inlet filters to Agilent InfinityLab quick-change inline filters, every design provides reliable particle retention and easy maintenance for analytical systems.
Our precolumn filters and microfilters safeguard column frits by capturing particulates before they reach the stationary phase, making replacement fast and cost-effective. Available in stainless-steel or PEEK materials, these filters ensure chemical resistance and consistent chromatographic performance.
We also offer inline solvent filters and biocompatible microfilters for low-volume venting applications, along with Upchurch Scientific® Frit-In-A-Ferrule components that combine sealing and filtration in one compact fitting.
Frequently Asked Questions
What is the purpose of a solvent inlet filter?
A solvent inlet filter prevents particles from entering the pump and flow path by filtering solvents directly inside the reservoir. This protection reduces blockages and prolongs system component life.
When should I use an inline filter instead of a precolumn filter?
Inline filters are installed between the pump and injector to trap contaminants from mobile phases, while precolumn filters sit before the analytical column to protect the column frit specifically. Many labs use both for full-path protection.
What are replacement frits made of?
Chrom Tech provides replacement frits made from stainless steel or durable PEEK, each offering precise porosity and chemical resistance suited for different solvent systems and pressure ranges.
How does a Frit-In-A-Ferrule work?
The Upchurch Scientific® Frit-In-A-Ferrule integrates a small frit into the ferrule body, allowing simultaneous sealing and filtration within the same connection—ideal for compact system layouts.
