Melting point capillary tubes supplied by LabChoice Australia provide clean, precise and thermally stable vessels for determining melting points, purity and phase transition behaviour of solid samples in analytical, teaching and industrial laboratory environments. Manufactured from high clarity BORO 3.3 borosilicate glass that complies with ISO 3585 and ASTM E438 Type 1 Class A standards, these tubes offer exceptional thermal stability, chemical inertness and resistance to deformation at elevated temperatures. Their uniform internal diameter and thin wall structure ensure consistent heat transfer for accurate and reproducible melting point measurements.

Each capillary tube is precisely cut, fire polished and batch tested to ensure smooth ends and internal uniformity that support consistent sample packing and reliable visual observation of melting behaviour. Open and sealed end variants are available depending on instrument compatibility and sample characteristics. The high clarity BORO 3.3 glass enhances visibility under magnification, enabling accurate detection of collapse point, initial melt and complete liquefaction during thermal analysis.

Melting point capillary tubes are widely used in pharmaceutical QC, organic synthesis, materials science, academic research, food chemistry, forensics and environmental analysis. They support routine purity checks, compound identification, thermal characterisation and method validation across a range of melting point apparatus types. Their inert glass construction prevents interaction with analytes, ensuring that melting point values reflect true material behaviour rather than contamination or sample degradation.

All melting point capillary tubes supplied by LabChoice Australia undergo ISO 9001 aligned quality control inspection. This includes dimensional accuracy checks, wall thickness verification, end finish assessment, clarity evaluation and thermal stability testing to ensure consistent performance during heating cycles. Tubes are fully validated for compliance with ISO 3585 and ASTM E438 borosilicate glass performance requirements. These rigorous measures guarantee accurate, consistent and contamination free results for laboratories requiring high precision thermal analysis consumables.
