Glass Capillary Tubes 75mm 200PCS Scienfocus Lab Borosilicate

Description

Product Overview

Scienfocus Lab presents a premium collection of 75mm glass capillary tubes designed for high‑precision laboratory work. Each tube is crafted from high‑quality borosilicate glass, delivering superior chemical resistance, thermal stability, and optical clarity. The tubes feature a 1.1mm inner diameter and a 1.5mm outer diameter, providing a consistent flow channel that minimizes dead volume and ensures reproducible results across repeated experiments. The open‑ended design on both sides facilitates straightforward sample loading and extraction without the need for additional connectors or adapters, streamlining workflow and reducing the risk of contamination.

Packaging includes 200 individually inspected tubes, each inspected for dimensional accuracy and surface integrity. The compact dimensions of the tubes (75mm length) make them easy to handle with standard laboratory pipettes, micro‑dispensers, and capillary holders. The lightweight yet robust construction allows for rapid manipulation while maintaining structural integrity during heating, cooling, or exposure to aggressive solvents.

These capillary tubes are compatible with a broad range of analytical techniques, including microfluidic assays, chromatography, spectrophotometry, and cell culture applications. Their transparent walls enable visual monitoring of fluid movement, facilitating real‑time observation of reaction progress or sample migration. The tubes are also suitable for educational settings, providing students with reliable tools for hands‑on learning in chemistry and biology labs.

Scienfocus Lab has incorporated user‑friendly features such as smooth, non‑sticky interior surfaces that reduce sample adhesion, ensuring that even low‑viscosity liquids can be drawn and expelled with minimal effort. The external surface is polished to a high sheen, allowing easy identification of tube orientation and preventing accidental breakage during handling. Each tube meets stringent quality standards, adhering to ISO 9001 guidelines for laboratory glassware.

Overall, the 75mm glass capillary tubes combine durability, precision, and ease of use, making them an essential component for any laboratory that demands reliable fluid handling and consistent experimental outcomes.

Usage

These capillary tubes excel in environments where small‑volume sampling is critical. Researchers conducting enzymatic assays, nucleic acid extractions, or microscale chemical syntheses can rely on the tubes to deliver exact volumes with repeatable accuracy. The open ends allow direct insertion of micro‑pipettes or syringes, eliminating the need for additional adapters and reducing setup time.

In diagnostic laboratories, the tubes are frequently employed for point‑of‑care testing, where rapid sample transfer and clear visual cues are paramount. Their borosilicate composition resists degradation from common reagents such as acids, bases, and organic solvents, ensuring that the integrity of the sample remains uncompromised throughout the analysis.

For quality‑control processes in manufacturing, the tubes provide a convenient means to collect and transport trace amounts of material for spectroscopic or chromatographic evaluation. Their uniform dimensions enable seamless integration with automated sampling systems, enhancing throughput while maintaining stringent quality standards.

Educational institutions benefit from the tubes’ durability and clarity, allowing students to observe capillary action, diffusion, and other fundamental phenomena. The tubes’ ease of cleaning and reusability make them a cost‑effective choice for repeated classroom demonstrations.

FAQ

What is the maximum temperature these capillary tubes can withstand?

The borosilicate glass used in our tubes is rated for continuous use up to 500 °C, making them suitable for most heating applications encountered in typical laboratory protocols.

Can the tubes be reused after cleaning?

Yes, the tubes can be cleaned with standard laboratory solvents such as ethanol or acetone. After thorough rinsing and drying, they retain their dimensional accuracy and surface smoothness for repeated use.

Are the tubes compatible with automated liquid handling systems?

Absolutely. The uniform length and diameter allow seamless integration with most robotic pipetting platforms and capillary loading devices, facilitating high‑throughput workflows.

What is the recommended storage condition to maintain tube integrity?

Store the tubes in a dry, dust‑free environment at room temperature. Avoid direct exposure to extreme humidity or mechanical shock, which could affect the glass surface.

How does the open‑ended design affect sample contamination risk?

The open ends are designed for quick access, but proper technique—such as using sterile pipette tips and minimizing exposure time—ensures that contamination risk remains low. The smooth interior surface also helps prevent sample adhesion, reducing cross‑contamination between uses.
