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

Description

Product Overview

FunChem delivers laboratory‑grade glass capillary tubes that combine precision engineering with reliable glass composition. Each tube measures 100mm in length, offering a convenient size for a wide range of analytical techniques. The inner diameter of 0.3mm and outer diameter of 0.5mm create a narrow channel that enables accurate micro‑volume transfer, essential for thin‑layer chromatography (TLC) spotting, microscale reactions, and sample handling where every microliter counts.

The tubes are manufactured from high‑purity borosilicate glass, providing chemical resistance to most solvents and reagents used in modern laboratories. This material choice ensures that the tubes maintain dimensional stability even under temperature fluctuations, reducing the risk of deformation that could compromise experimental results. The smooth interior surface minimizes sample adhesion, allowing for clean and repeatable transfers.

Packaging includes a generous supply of 1,000 tubes, reducing the need for frequent reordering and supporting large‑scale projects or teaching laboratories with high throughput demands. Each tube is individually inspected to meet strict quality standards, guaranteeing uniformity across the entire batch.

While the glass construction offers superior performance, it also requires careful handling. The thin walls make the tubes fragile, so users should employ appropriate tools such as tweezers or tube holders and avoid excessive bending. Proper storage in a protective container helps prevent accidental breakage.

FunChem backs each purchase with a responsive after‑sales service. If any tube arrives damaged or defective, customers can contact support for a replacement or refund, ensuring confidence in every experiment.

Usage

These capillary tubes excel in environments where precision and minimal sample loss are paramount. In analytical chemistry labs, they are routinely used for spotting samples onto TLC plates, where the narrow bore allows for tightly defined spots that improve resolution and reproducibility. Researchers conducting microscale syntheses benefit from the ability to transfer sub‑microliter volumes without contamination.

Educational settings, such as university chemistry courses, find the tubes valuable for teaching concepts of capillary action, chromatography, and quantitative analysis. The clear glass provides visual feedback, helping students understand fluid movement in confined spaces.

Industrial quality‑control laboratories employ the tubes for rapid screening of product batches, where quick and accurate sampling can accelerate decision‑making. The tubes are also compatible with automated liquid‑handling systems that can be programmed to draw and dispense precise volumes, integrating seamlessly into high‑throughput workflows.

Because the tubes are chemically inert, they can be used with a broad spectrum of solvents, acids, bases, and organic reagents. This versatility makes them suitable for applications ranging from pharmaceutical development to environmental testing.

FAQ

What is the recommended method for handling these fragile glass tubes?

Use tweezers or a dedicated tube holder to avoid direct finger contact. When transferring liquids, gently draw the sample into the tube using a syringe or capillary action, and avoid bending the tube beyond its natural curvature.

Can these capillary tubes be used with organic solvents?

Yes. The borosilicate glass composition is chemically inert to most organic solvents, acids, and bases commonly used in laboratory settings, making the tubes suitable for a broad range of applications.

How do I store the tubes to prevent breakage?

Keep the tubes in a protective container or a padded box, away from sharp edges and heavy objects. Store them in a temperature‑controlled environment to minimize thermal stress, and handle them with care during inventory checks.

What should I do if I receive a damaged tube?

Contact FunChem customer support within the return window, providing the order number and a photo of the damage. Our team will arrange a replacement or refund promptly, ensuring your experiments can continue without delay.

Are these tubes compatible with automated liquid handling systems?

Yes. The standardized dimensions and smooth interior allow integration with many robotic pipetting platforms. Verify the compatibility of your specific system’s tips or adapters, and adjust the dispensing parameters to match the 0.3mm inner diameter for optimal performance.
