Stainless steel (SS) capillary tubing is widely recognized for its superior performance in high-precision applications, particularly in fields like chromatography, medical devices, and industrial processes. This tubing is engineered to provide precise flow control, high durability, and resistance to corrosion, making it an essential component in systems where accuracy and reliability are paramount.
SS capillary tubing is precision-engineered to ensure consistent flow and high separation efficiency. This is particularly important in applications such as high-performance liquid chromatography (HPLC) and gas chromatography (GC), where the tubing's inner diameter and surface finish can significantly affect the separation and detection of analytes.
In HPLC systems, SS capillary tubing is used to connect various components such as columns, pumps, and detectors. The tubing's precision engineering ensures that there are no dead volumes or irregularities that could compromise the system's performance.
SS capillary tubing is available in various materials, including stainless steel, MP35N, PEEK-lined, and titanium. Each material offers unique properties that cater to different applications:
- Stainless Steel: Known for its strength, corrosion resistance, and affordability, stainless steel tubing is ideal for most chromatography applications.
- MP35N: Offers superior strength and corrosion resistance, making it suitable for high-pressure applications.
- PEEK-lined: Provides an inert surface, reducing the risk of sample contamination, which is crucial in biological and pharmaceutical analyses.
- Titanium: Lightweight and highly resistant to corrosion, often used in medical devices.
The use of laser-welded ends in SS capillary tubing eliminates dead volumes, ensuring that the flow path is uninterrupted. This feature is critical in maintaining the system's efficiency and preventing any potential contamination or sample loss.
SS capillary tubing is designed to be compatible with leading chromatography instruments, such as those from Agilent. Its durability and flexibility make it suitable for high-pressure environments, allowing for minimal bending without compromising its integrity.
To simplify the identification process, SS capillary tubing is often color-coded based on its inner diameter. This feature helps users quickly select the appropriate tubing size for their specific application.
In chromatography, SS capillary tubing plays a vital role in connecting different components of the system. Its precision and durability ensure that the chromatographic process is efficient and reliable.
While SS capillary tubing is highly effective, there are alternative materials and technologies available, such as fused silica and PEEK tubing. Each has its advantages and is chosen based on the specific requirements of the application.
Proper cutting and handling of SS capillary tubing are crucial to prevent damage and ensure optimal performance. Techniques such as using a ceramic scribe column cutter help maintain the tubing's integrity.
SS capillary tubing is a cornerstone in high-precision applications due to its precision engineering, material variety, and durability. Its widespread use in chromatography and other fields underscores its reliability and performance. As technology advances, the demand for high-quality SS capillary tubing will continue to grow, driving innovation in manufacturing processes and material science.
SS capillary tubing is primarily made from stainless steel, but other materials like MP35N, PEEK-lined, and titanium are also used, each offering unique properties for different applications.
The inner diameter of SS capillary tubing significantly affects flow control and separation efficiency. Smaller diameters provide better flow control but may increase the risk of clogging.
Laser-welded ends eliminate dead volumes, ensuring uninterrupted flow and improving system performance by reducing the risk of contamination or sample loss.
While SS capillary tubing is versatile, it is not recommended for biological samples due to potential carryover issues unless specifically designed with an inert surface, such as PEEK-lined tubing.
SS capillary tubing should be cut using a ceramic scribe column cutter to avoid burrs and jagged edges. It should be handled carefully to prevent kinking and damage.
