Capillary Tube 4pcs 304 Stainless Steel 7mm OD 6mm ID 250mm by Yodaoke

Description

Product Overview

The Yodaoke capillary tube set includes four high‑quality tubes made from 304 stainless steel, a material renowned for its superior corrosion resistance, mechanical strength, and biocompatibility. Each tube features a precise outer diameter of 7 mm and an inner diameter of 6 mm, creating a wall thickness of 0.5 mm that balances flexibility with rigidity. The length of 250 mm (9.84 inches) provides ample reach for a wide range of laboratory procedures, from simple fluid transfer to complex micro‑fluidic experiments. The tubes are manufactured to exacting tolerances, ensuring consistent inner channel dimensions that promote accurate flow rates and reproducible results. Their smooth interior surface minimizes friction and prevents sample contamination, making them ideal for sensitive analytical applications. The set is packaged in a compact, protective container that keeps the tubes secure during storage and transport, and the clear labeling on each tube helps users quickly identify the correct size for their specific protocol.

Usage

These stainless steel capillary tubes are designed for versatile use across many scientific disciplines. In chemistry labs, they serve as reliable conduits for transferring reagents, performing titrations, and setting up gas‑liquid reactions where precise volume control is essential. In biology and medical research, the tubes are perfect for handling small liquid samples, such as blood, serum, or cell culture media, without risking adsorption or degradation of delicate biomolecules. The robust construction also makes them suitable for high‑temperature applications, including heating, sterilization, and exposure to aggressive solvents, where standard glass capillaries might crack or break. Engineers working on micro‑fluidic devices appreciate the uniform inner diameter, which enables predictable laminar flow and accurate pressure calculations. Additionally, the tubes can be integrated into custom rigs, such as flow reactors, chromatography setups, or analytical instrumentation, providing a dependable pathway for fluids under a variety of pressures and flow regimes.

FAQ

What types of chemicals can these capillary tubes safely handle?

The 304 stainless steel material is compatible with most aqueous solutions, organic solvents, acids, and bases commonly used in laboratory settings. However, extremely aggressive chemicals such as hydrofluoric acid or strong oxidizers may require special handling or alternative materials.

Can the tubes be sterilized for biological applications?

Yes, the tubes can be autoclaved at standard temperatures (121 °C) without deformation. They also tolerate chemical sterilization methods, such as ethanol or bleach rinses, making them suitable for microbiology and cell culture work.

How do I clean the inner surface after use?

Flush the tube with a suitable solvent (e.g., distilled water followed by isopropyl alcohol) and use a gentle air pressure or a syringe to push the cleaning solution through the tube. For stubborn residues, a mild ultrasonic bath can be employed, ensuring the tube is thoroughly dried before the next use.

Is there a warranty or guarantee on these capillary tubes?

Yodaoke offers a one‑year limited warranty covering manufacturing defects. If you encounter any issues related to material quality or dimensional accuracy, contact our support team for a replacement or refund.
