Quick answer: A Thiele Melting Point Tube uses a side-arm design that creates natural convection currents in a heating oil bath, distributing heat evenly for accurate melting point determination of a solid sample. Theil Melting Point Tube is priced at approximately ₹165 (indicative market benchmark, incl. GST, August 2026).
A Thiele tube is a specialized glass vessel with a side arm shaped to create natural convection currents when the oil bath inside is heated at the bottom. This convection continuously circulates the heated oil, distributing temperature evenly around a sample tube held in the main body, without needing a stirrer. That even heating supports accurate, repeatable melting point determination — a standard technique for identifying and checking the purity of a solid compound in college and research chemistry laboratories.
