Glass Melting Point Capillary Tube 80mm 0.9-1.1mm ID Deschem 500PCS

Description

Product Overview

The Deschem 80mm glass melting point capillary tube is engineered for laboratories that demand precision, repeatability, and durability in thermal analysis. Constructed from high‑purity borosilicate glass, each tube offers excellent resistance to chemical corrosion and thermal shock, making it suitable for repeated heating cycles without compromising structural integrity. The inner diameter of 0.9‑1.1mm provides a narrow channel that promotes uniform heat transfer, while the one‑end closed design prevents sample leakage and ensures accurate melting point determination.

With a total length of 80mm, the tube offers sufficient space for sample loading and easy handling during experiments. The outer diameter is optimized for compatibility with standard laboratory equipment such as capillary tube holders, heating blocks, and temperature controllers. Each package contains 500 tubes, delivering a cost‑effective solution for high‑throughput testing environments, educational institutions, and research facilities that require a reliable supply of consistent glassware.

Beyond its core specifications, the tube’s transparent glass allows visual inspection of the sample throughout the testing process, facilitating real‑time observation of phase changes. The product complies with industry standards for laboratory glassware, ensuring that it meets the rigorous quality expectations of scientific professionals. Its design minimizes the risk of breakage during routine handling, and the closed end reduces the chance of contamination, supporting clean and reproducible results.

Deschem, a recognized manufacturer in the scientific supplies sector, guarantees that each batch undergoes strict quality control procedures. The tubes are inspected for dimensional accuracy, surface smoothness, and absence of defects, providing confidence that every tube performs as intended. This attention to detail makes the 80mm capillary tube a trusted component for melting point determination, viscosity measurements, and other temperature‑sensitive analyses.

Overall, the 80mm glass melting point capillary tube combines functional design, material excellence, and bulk availability to meet the diverse needs of modern laboratories. Whether used in academic research, industrial quality control, or routine teaching labs, the tube delivers consistent performance that supports accurate data collection and reliable scientific outcomes.

Usage

These capillary tubes are ideal for a wide range of applications, including melting point determination of organic compounds, polymer analysis, and calibration of temperature measurement devices. In a typical workflow, a small amount of sample is introduced into the open end of the tube using a micro‑spatula or syringe, then the tube is sealed at the closed end to prevent evaporation during heating.

During analysis, the tube is placed in a calibrated heating block or oil bath, where the temperature is gradually increased. The transparent glass enables the operator to observe the exact moment of melting, allowing precise recording of the melting point. This method is widely adopted in pharmaceutical quality control, where accurate melting point data is essential for verifying compound purity and identity.

The tubes also serve well in educational settings, providing students with hands‑on experience in thermal analysis techniques. Their robust construction tolerates the frequent handling typical of teaching labs, while the closed end design simplifies safety protocols by containing potentially hazardous substances.</n

In industrial environments, the 500‑piece pack ensures that large‑scale testing can be performed without interruption, supporting continuous production monitoring and batch verification. The tubes are compatible with automated capillary loading systems, enabling integration into high‑throughput workflows that increase efficiency and reduce manual labor.

For researchers conducting exploratory studies, the tubes’ consistent dimensions and clear glass facilitate reproducibility across experiments, a critical factor when comparing results over time or between different laboratories.

FAQ

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

Samples should be introduced into the open end of the tube using a fine‑tipped micro‑spatula, syringe, or capillary filler device. Ensure the sample does not exceed the tube’s inner diameter to avoid blockage. After loading, gently seal the closed end with a flame or heat source to prevent evaporation during heating.

Can these tubes be reused after a melting point test?

While the glass material is durable, reusing the same tube for multiple tests is not recommended because residual material may affect subsequent measurements. For consistent results, it is best to use a fresh tube for each new sample. However, if a tube is thoroughly cleaned and inspected for damage, it may be reused in non‑critical applications.

Are the tubes compatible with automated capillary loading systems?

Yes, the tubes are designed to fit standard automated loading equipment used in high‑throughput laboratories. Their uniform dimensions and smooth interior surface allow for reliable operation with robotic dispensers, reducing manual handling and increasing efficiency.

What safety precautions should be taken when handling the closed end of the tube?

The closed end is sealed by heating, creating a small glass seal that can be fragile. Use protective gloves and eye protection when handling sealed tubes, and avoid applying excessive force. If the seal needs to be opened, do so with a specialized glass cutter or by gently heating the seal under a fume hood to prevent accidental breakage.

How should the tubes be stored to maintain their quality?

Store the tubes in a dry, temperature‑controlled environment away from direct sunlight and mechanical stress. Keep them in their original packaging or a protective container to prevent breakage. Avoid exposure to extreme temperature fluctuations, which could compromise the glass integrity.
