Melting Point Apparatus 931\u003c\/h4\u003e\nSilicon oil provides several advantages for melting point determination: it offers excellent heat capacity and distribution properties, maintains uniform temperature throughout the bath (especially with magnetic stirring), allows clear visibility of samples, has a high boiling point suitable for the full temperature range (0-300°C), and provides stable, controlled heating characteristics essential for precise melting point measurement.\n\u003ch4\u003eHow does the magnetic stirrer improve measurement accuracy? Melting Point Apparatus 931\u003c\/h4\u003e\nThe integrated magnetic stirrer ensures uniform temperature distribution throughout the oil bath by preventing temperature stratification (layering). Without stirring, temperature gradients could develop where the oil near the heating element becomes hotter than oil at the sample position, leading to inaccurate readings. Constant stirring maintains consistent temperature throughout the bath for more reliable measurements.\n\u003ch4\u003eWhat is the purpose of the High\/Low range temperature selector? Melting Point Apparatus 931\u003c\/h4\u003e\nThe High\/Low range selector optimizes the heating control characteristics for different temperature ranges. For lower melting point samples, the Low range selection provides more precise control and finer temperature adjustment in the lower temperature ranges. For higher melting point samples, the High range selection is optimized for the upper temperature spectrum, ensuring accurate readings throughout the full 0-300°C range.\n\u003ch4\u003eCan I test both melting points and boiling points with this apparatus? Melting Point Apparatus 931\u003c\/h4\u003e\nYes, the Melting Point Apparatus Model 931 is designed to measure both. The Teflon cover has specific positions for three capillary tubes (for solid sample melting points) and one dedicated position for a boiling point tube (for liquid sample boiling points). The included accessories package contains both standard capillaries and specialized boiling point tubes for this purpose.\n\u003ch4\u003eHow many samples can be tested simultaneously?\u003c\/h4\u003e\nThe apparatus can test up to three solid samples simultaneously using the three capillary positions in the Teflon cover. This allows for testing multiple samples in parallel or running replicates of the same sample for verification, increasing laboratory efficiency and testing throughput.\n\u003ch3\u003eSummary Melting Point Apparatus 931\u003c\/h3\u003e\nThe Melting Point Apparatus Model 931 by Electronics India represents a practical and reliable solution for laboratories requiring accurate melting point determination. This ISO 9001:2000 certified instrument combines essential features for precise testing with a user-friendly design suitable for pharmaceutical laboratories, chemical analysis facilities, and educational institutions.\n\nKey advantages include the silicon oil bath with integrated magnetic stirrer for uniform heating, multi-position sample testing capability, enhanced visibility through magnifier and glare-free illumination, and versatile temperature range (0-300°C). The included high-quality accessories, such as the 0-360°C thermometer, capillaries, boiling point tubes, and magnetic capsule, ensure the apparatus is ready for immediate use upon delivery.\n\nWith its compact footprint (235 × 285 × 160mm), lightweight design (8.7 kg), and practical feature set, the Melting Point Apparatus Model 931 offers excellent laboratory value while maintaining the precision and reliability required for critical testing applications. The ability to test both melting points of solid samples and boiling points of liquid samples enhances its versatility as a laboratory instrument.\n\nBacked by Electronics India's reputation for quality instrumentation and protected by a 1-year warranty, the Melting Point Apparatus Model 931 delivers professional-grade performance for melting point analysis across a wide range of solid samples, making it an essential tool for any quality-focused laboratory requiring reliable physical property testing.","brand":"Electronics India","offers":[{"title":"Default Title","offer_id":51460965499126,"sku":"EI-MEL-931","price":38350.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/6535\/1158\/files\/Melting_Point_Apparatus_931__81698.1754463759.386.513_7fea31fe-9c86-4e7d-8cb5-f8b53c8eb10d.jpg?v=1786598909","url":"https:\/\/scispectrum.in\/products\/melting-point-apparatus-931","provider":"SciSpectrum Lab Essentials","version":"1.0","type":"link"}
