Overview

This product is a precision chromatography column tube made of high-purity stainless steel 316L material. It is specially designed for high-performance liquid chromatography (HPLC) systems and manufactured using imported excellent processes. It has high column efficiency, stability, and reproducibility, and is suitable for high-precision analysis experiments and rigorous scientific research needs. $r $n $r $n supports customized services (such as special sizes and materials), please contact our technical advisor for details.

Product Details

Core advantages:

1. Using imported high-precision CNC machine tools for processing, ensuring that the dimensional tolerance of the pipe body is controlled within a controllable range, and achieving good quality between batches at once.

2. The inner wall of the pipe has high smoothness, no burrs, good concentricity, smooth inner wall [smoothness<0.1um], and high column efficiency.

3. The column head plays a crucial role in ensuring high repeatability during loading in HPLC chromatography columns. Fix the chromatographic column head with a sieve plate, connect the chromatographic column to the chromatographic system, and provide a leak free connection. The design and processing of chromatographic column heads have zero dead corners and no dead volume.

4. The chromatographic column tube has a small dead volume, high sealing, no leakage, high permeability of the sieve plate, good column efficiency, and high repeatability.

5. Column tubes can meet import standards and can replace imported column tubes.


Application adaptability:

1. Column efficiency index: According to third-party testing (referring to USP standards), the theoretical number of trays (N/m) has increased by 15% -20% compared to similar domestic products, meeting the high-resolution separation requirements of complex samples.

2. Defect free production: strict quality inspection throughout the entire process, with a defect rate of less than 0.01%, ensuring the reliability and safety of each batch of products.

3. Standard configuration: one empty column tube, two column caps, two PEEK cap sieve plates, and two plugs.

4. Wide compatibility: Suitable for various packing types such as C18, C8, HILIC, etc., supporting chromatographic modes such as reverse phase and ion exchange.

5. Reproducibility guarantee: The ultra smooth surface and uniform diameter design inside the tube ensure that the filling density deviation is less than 2%.
