HPLC column hardware and packing components are used to assemble, protect, and pack chromatography columns for analytical and preparative applications. This category includes PEEK column hardware, end fittings, frits, packing adapters, slurry reservoirs, and replacement components, supporting both bioinert and conventional chromatography configurations.
These components are used by column‑packing professionals and laboratory users who assemble columns in‑house, maintain packed columns, or configure custom column formats for specific methods. Proper selection of column hardware is essential for maintaining packing integrity, minimizing dead volume, and achieving reproducible chromatographic performance.
All‑PEEK Column Hardware Systems
This category includes All‑PEEK column hardware and complete column sets manufactured using extruded PEEK tubing for high dimensional consistency and bioinert operation. Carbon (20%) is incorporated into the PEEK formulation to achieve the characteristic black surface finish; no additional chemical coatings or surface treatments are applied.
Because the internal bore is not treated or coated, the column interior develops a smooth, reflective surface through the extrusion process alone, making these columns well suited for bio‑sensitive and metal‑free applications.
Column Frits & Packing Retention
Frits are used to retain packing material while allowing consistent mobile‑phase flow. Available options include:
PEEK frits with 2 µm porosity
Titanium (Ti) frits with 0.5 µm, 2 µm, or 5 µm porosity
These frit options support different particle sizes and application requirements while maintaining chemical compatibility and pressure stability. Frit selection should match packing material and operating pressure.
Column Sizes & Thread Configurations
Hardware is available to support common analytical column formats, including:
2.1 mm ID columns – 1/4‑28 threads
3.0 mm ID guard cartridge systems
4.6 mm ID columns – 1/2‑20 threads
7.5 mm ID columns – 5/8‑18 threads
Thread selection is critical for proper sealing and compatibility with packing stations and system fittings.
Packing Hardware, Slurry Reservoirs & Replacement Parts
This category also includes components required for column packing and maintenance, such as:
Slurry reservoir kits for controlled packing operations
All‑PEEK packing adapters and end fittings
Replacement seals and packing hardware components
These items are used during initial column packing and for servicing or repacking columns over time.
Applications & Use Cases
HPLC column hardware and packing components in this category are commonly used for:
In‑house packing of analytical and preparative columns
Bioinert chromatography workflows
Custom column configurations and method development
Column repair, maintenance, and lifespan extension
Research, pharmaceutical, and OEM environments
Important Material Consideration
⚠️ Temperature caution: PEEK column hardware and components experience a significant reduction in pressure stability at elevated temperatures. Operating conditions should be selected carefully to avoid exceeding material limits during high‑temperature chromatography.
