Labasics Glass Capillary Tubes 100mm 0.3mm ID/0.5mm OD Pack of 1000

Description

Product Overview

Labasics Glass Capillary Tubes are engineered for high‑precision laboratory applications where consistency and reliability are paramount. Each tube measures exactly 100 mm in length, providing ample reach for a variety of experimental setups while maintaining a compact profile that fits easily into standard laboratory racks and holders. The inner diameter of 0.3 mm and outer diameter of 0.5 mm are tightly controlled within a tolerance of ±0.1 mm, ensuring uniform capillary action across the entire batch. This uniformity is essential for thin‑layer chromatography (TLC) spotting, micro‑volume liquid transfers, and other analytical techniques that depend on reproducible fluid dynamics.

The tubes are fabricated from high‑quality borosilicate glass, a material known for its chemical resistance, thermal stability, and optical clarity. Borosilicate glass can withstand a wide range of solvents, acids, and bases without degrading, making these capillaries suitable for both routine and demanding chemical processes. The transparent nature of the glass allows users to visually monitor liquid movement, facilitating precise control during sample application and transfer.

Packaged in a convenient bulk quantity of 1,000 units, the product is ideal for laboratories, research institutions, and educational facilities that require a steady supply of reliable capillary tubes. Each purchase is backed by a one‑year limited manufacturer warranty, reflecting Labasics’ confidence in the durability and performance of their glassware.

Usage

These capillary tubes excel in environments where precise fluid handling is critical. In TLC, the 0.3 mm inner diameter allows for the deposition of minute sample volumes, creating sharp, well‑defined spots that improve resolution and reproducibility. Researchers can use the tubes to apply samples to silica gel plates, alumina layers, or other stationary phases with confidence that the volume delivered will be consistent from one application to the next.

Beyond chromatography, the tubes are valuable for micro‑pipetting tasks such as transferring nanoliter to microliter volumes of reagents, catalysts, or biological samples. Their slender profile enables access to tight spaces within reaction vessels, microfluidic devices, and analytical instruments. The chemical inertness of borosilicate glass ensures that the tubes do not introduce contaminants or react with the substances they carry, preserving sample integrity.

In educational settings, the tubes serve as a hands‑on teaching tool for demonstrating capillary action, surface tension, and fluid dynamics. Their durability allows repeated use in classroom labs, while the clear glass provides a visual aid for students learning fundamental concepts in chemistry and physics.

Why Choose Us

Labasics stands out in the laboratory glassware market due to a commitment to quality, consistency, and customer support. Each batch of capillary tubes undergoes rigorous dimensional verification to guarantee that the 0.3 mm ID and 0.5 mm OD specifications are met with tight tolerances. This level of precision reduces variability in experimental results, a critical factor for researchers seeking reproducible data.

The use of premium borosilicate glass provides superior resistance to thermal shock and chemical attack, extending the usable life of each tube even under harsh laboratory conditions. Unlike lower‑grade glass, Labasics tubes maintain their structural integrity when exposed to rapid temperature changes or aggressive solvents, minimizing the risk of breakage or deformation.

FAQ

What solvents can these capillary tubes safely handle?

The borosilicate glass construction is compatible with most organic solvents, acids, and bases commonly used in laboratory work, including ethanol, methanol, acetone, hydrochloric acid, and sodium hydroxide solutions. However, extremely aggressive fluorinated solvents should be used with caution.

How do I store the tubes to maintain their integrity?

Store the tubes in a clean, dry environment away from direct sunlight and extreme temperature fluctuations. Keeping them in a protective container or drawer prevents accidental breakage and reduces dust accumulation.

Can these tubes be autoclaved for sterilization?

Yes, the borosilicate glass can withstand standard autoclave cycles (121 °C, 15 psi) without deformation. Autoclaving is recommended for applications involving biological samples to ensure sterility.

What is the procedure for filing a warranty claim?

Contact Labasics customer support with the purchase details and a description of the issue. Provide photos if possible. The support team will guide you through the return process and arrange a replacement or refund according to the warranty terms.

Are the tubes compatible with standard capillary tube holders?

Yes, the 0.5 mm outer diameter conforms to industry‑standard dimensions, allowing seamless use with most commercial capillary tube racks, holders, and micro‑pipetting devices.
