3.0 Empty HPLC Column Hardware For HPLC & LC-MS/MS Lab Equipment Liquid Chromatography

Short Description:

Empty HPLC Column (Each column blank kit) includes a precision-bore polished 316 stainless steel column blank, two column heads and ferrules for OD1/16” column end plugs, and two 2µm frit caps.

Empty HPLC Hardware

Stainless Steel Analytical Column Hardware

• Threaded tube for easy assembly

• Type 316 stainless steel construction

• Column ID of 2.1, 3.0, 4.0, and 4.6mm

Features and Applications:

Empty chromatography columns (analytical, semi-preparative, and preparative)

1. Precision machined chromatography column tubes made of high-purity 316L type stainless steel tubing.

2. Available in a wide range of sizes from analytical to preparative.

3. Very small dead volume, smooth inner tube walls, and uniformly rounded cross-section; ensures high performance of the finished column; high consistency and reproducibility and reproducibility.

4. To ensure high reproducibility during loading, the column head plays a critical role in the HPLC column. The chromatographic column head sieve plate connects the column to the chromatographic system and provides a leak-free connection. The column head must be designed and machined to eliminate dead space, dead volume, and unnecessary off-column volume. Failure to do so will result in broad peaks and low column efficiency.

5. The column tip must be designed and machined to provide a leak-free seal with dead and off-column volumes.

  • uHPLCs introduces an assortment of advanced preparative hardware, tailored to meet diverse chromatographic needs.
  • The frit cap, fabricated from Stainless Steel, is meticulously designed to minimize leakage, enhancing the overall performance and longevity of the hardware.
  • The structure eliminates any points susceptible to bending or bowing, allowing for an impressive pressure resistance, exceeding 15,000 psi, and potentially reaching up to 25,000 psi.
  • The cap features a specifically engineered flow path that promotes uniform loading and superior dispersion, optimizing the preparative process.
  • uHPLCs also offers customization and packing hardware for all Preparative Columns, enhancing adaptability to different chromatographic requirements, thereby reaffirming uHPLCs’ commitment to precision and quality.

Column body

This is a measure of the distribution of particles packed in a column. In HPLC, it is preferable to have narrow particle size distribution as a narrow particle size distribution can lead to better HPLC column efficiency.


In LC chromatography the reaction of a silylating agent with unreacted accessible silanols remaining on the silica gel surface after the initial bonding reaction of the HPLC column stationary phase. HPLC column endcapping eliminates unwanted secondary silanol interactions between compounds and the stationary phase.

PEEK frit

Longer filtration life
Consistent frit-to-frit swept volumes
Biocompatible and inert to most solvents
Suitable for low and high pressure applications.
Enhanced sealing and excellent chemical resistance.
PEEK frits can be used up to 80 ºC.
