Capillary Tube 12mm OD x 11mm ID 250mm Length 304 Stainless Steel

Description

Product Overview

The Yodaoke capillary tube set delivers professional‑grade performance for a wide range of laboratory applications. Each tube is fabricated from premium 304 stainless steel, a material renowned for its excellent corrosion resistance, mechanical strength, and ability to maintain dimensional stability under harsh chemical environments. With an outer diameter of 12 mm, an inner diameter of 11 mm, and a precise length of 250 mm, these tubes provide a consistent internal volume that is essential for accurate fluid handling, sample transport, and micro‑scale reactions.

Designed with a wall thickness of 0.5 mm, the tubes balance rigidity and flexibility, allowing users to route them through tight spaces while resisting deformation during high‑pressure operations. The seamless construction eliminates the risk of leaks at joints, which is critical when working with volatile or hazardous substances. The set includes two identical tubes, offering redundancy for experiments that require parallel processing or backup components.

Beyond the core specifications, Yodaoke has implemented strict quality control procedures throughout the manufacturing process. Each tube undergoes ultrasonic cleaning, dimensional verification, and surface finish inspection to ensure that the final product meets exacting laboratory standards. This attention to detail translates into reliable, repeatable results for researchers who demand precision in every step of their workflow.

Usage

These capillary tubes excel in a variety of scientific settings, including analytical chemistry, biotechnology, and materials science. They are particularly well‑suited for chromatography columns, where the uniform inner diameter promotes consistent flow rates and sharp peak resolution. In addition, the tubes serve as ideal conduits for fluid sampling in environmental testing, allowing technicians to draw precise volumes of water, soil extracts, or air condensates without contamination.

In micro‑reaction setups, the robust stainless‑steel construction tolerates elevated temperatures and pressures, enabling researchers to explore reaction kinetics that would otherwise damage more fragile glassware. The tubes also integrate seamlessly with standard laboratory fittings, such as Luer lock connectors and stainless‑steel clamps, providing a versatile interface for custom apparatuses. Whether you are assembling a custom flow‑through system or performing routine sample transfers, the Yodaoke capillary tubes deliver dependable performance.

FAQ

What types of chemicals can these tubes safely handle?

The 304 stainless steel material is compatible with a broad range of chemicals, including most acids, bases, and saline solutions. However, it is not recommended for use with highly concentrated hydrofluoric acid or strong oxidizing agents such as concentrated nitric acid, which can compromise the metal over time.

Can the tubes be sterilized for microbiology work?

Yes, the tubes can be autoclaved at standard temperatures (121 °C) without deformation. The stainless‑steel surface also tolerates chemical sterilization methods, such as ethanol or bleach rinses, making them suitable for microbiological applications.

Are the tubes compatible with standard laboratory fittings?

Absolutely. The outer diameter of 12 mm aligns with common stainless‑steel clamps, Luer lock adapters, and custom‑machined fittings. This compatibility allows seamless integration into existing fluid‑handling systems.

What is the recommended storage condition to maintain tube integrity?

Store the tubes in a dry, temperature‑controlled environment away from direct sunlight and corrosive vapors. Keeping them in a sealed container with a desiccant will further protect the surface finish and prevent moisture‑induced corrosion.
