Glass Capillary Tubes RGULICX 0.3mm OD 100mm Length 1000 Pack Lab Use

Description

Product Overview

The RGULICX Glass Capillary Tubes are engineered to meet the exacting standards of modern analytical laboratories. Each tube measures 100 mm in length with a precise 0.3 mm outer diameter, providing a reliable conduit for micro‑volume sample transfer. Constructed from high‑quality borosilicate glass, the tubes exhibit excellent chemical resistance, ensuring that they do not react with solvents, reagents, or analytes during thin‑layer chromatography (TLC) or other sensitive procedures. The transparent nature of the glass allows technicians to visually confirm sample placement, reducing the risk of misapplication and improving overall experimental accuracy. With a total of 1000 tubes per package, the product delivers a cost‑effective solution for laboratories that require a steady supply of capillary tubes for routine analyses, method development, and quality control. The design incorporates a smooth internal surface that minimizes capillary action resistance, enabling consistent delivery of approximately 7 µL per draw, which is ideal for spotting TLC plates with uniform sample volumes. Additionally, the tubes are lightweight, weighing only 2.4 ounces for the entire pack, and are compactly packaged in dimensions of 4.7 × 1.9 × 1.9 inches, facilitating easy storage and inventory management. The product has earned a solid reputation among users, reflected in a 5‑star rating based on multiple reviews, and holds a competitive ranking within the capillary tube category on major e‑commerce platforms.

Usage

These capillary tubes are ideally suited for a wide range of laboratory applications where precise, low‑volume handling is essential. In thin‑layer chromatography, the 0.3 mm diameter enables fine, controlled spotting of samples onto silica gel plates, allowing for sharp, well‑defined bands that improve resolution and reproducibility. Beyond TLC, the tubes are valuable for microscale reactions, where they can be used to transfer reagents between vials, add catalysts in sub‑microliter quantities, or withdraw aliquots for analytical testing such as gas chromatography or mass spectrometry. The tubes’ durability and chemical inertness make them appropriate for use with a variety of solvents, including polar and non‑polar media, without risk of degradation or leaching. Researchers in academic, industrial, and clinical settings benefit from the ease of handling provided by the smooth glass surface, which reduces the likelihood of clogging or sample loss. The bulk quantity of 1000 tubes ensures that high‑throughput laboratories can maintain uninterrupted workflows, while the consistent dimensions guarantee that automated spotting devices can be calibrated once and used reliably across multiple experiments. Proper handling guidelines, such as avoiding excessive force and storing the tubes in a protective container, help preserve their integrity and extend their usable lifespan.

FAQ

What is the recommended method for loading sample into the capillary tube?

To load a sample, first ensure the tube is clean and free of any residual solvent. Using a micropipette or a syringe with a fine needle, draw the desired volume (typically up to 7 µL) and gently dispense it onto the open end of the tube. Capillary action will draw the liquid upward; avoid applying excessive pressure, which can cause the glass to fracture. Once the sample reaches the appropriate height, the tube can be used directly for spotting or transferred to the target substrate.

Can these tubes be reused after cleaning?

Yes, the glass material allows for careful cleaning and reuse in many cases. After use, soak the tube in an appropriate solvent to dissolve any residue, then rinse thoroughly with distilled water and dry with a lint‑free tissue. For applications requiring absolute cleanliness, consider using a fresh tube to prevent cross‑contamination. Always inspect the tube for micro‑cracks before reuse, as repeated handling can weaken the glass.

Are the tubes compatible with automated spotting instruments?

Absolutely. The uniform 0.3 mm outer diameter and 100 mm length are engineered to match the specifications of most automated TLC spotters and micro‑dispensing platforms. When configuring the instrument, set the dispensing parameters to accommodate the tube’s internal volume (approximately 7 µL) and ensure the loading mechanism aligns with the tube’s open end. Calibration may be required the first time the tubes are introduced, but once set, the system will reliably deliver consistent spots across multiple runs.

What safety precautions should be taken when handling these glass tubes?

Although the tubes are made from durable borosilicate glass, they are still fragile due to their thin walls. Handle them with care, using tweezers or a tube holder when possible, and avoid dropping or applying sudden force. Wear appropriate personal protective equipment, such as safety glasses and gloves, to protect against accidental breakage. Store the tubes in a padded container to minimize the risk of damage during transport or storage.

How does the bulk packaging benefit large laboratories?

The 1000‑piece pack is designed for high‑throughput environments where frequent tube replacement can interrupt workflow. By providing a large inventory in a single package, laboratories reduce the time and cost associated with ordering smaller quantities. The compact packaging dimensions also free up valuable storage space, and the consistent quality across the entire batch ensures that every tube performs identically, simplifying method validation and quality control procedures.
