Digital Melting Point Apparatus Model 2935: High-Resolution TFT Camera for Pharmaceutical and Lab Use
Introduction to Melting Point Determination
The Melting Point Apparatus is a precision instrument designed for measuring the melting point and checking the melting range of solid samples. The determination of a substance's melting point is a fundamental technique used in organic chemistry and pharmaceutical production to identify the nature of a compound and determine its purity. Pure substances exhibit a sharp and narrow melting range.
The Digital Melting Point Apparatus Model 2935 is designed by Electronics India (EI) and utilizes advanced features for efficient and highly accurate measurement, serving as a reliable tool for analytical, scientific laboratory, and pharmaceutical applications.
Key Features and Advantages
The Model 2935 combines sophisticated digital controls with advanced visual confirmation technology, offering superior performance for melting point determination:
• High Accuracy and Ease of Operation: This apparatus is highly accurate and designed to be easy to operate, ensuring reliable results for critical purity assessments.
• Integrated Viewing System: The unit is equipped with a TFT screen and a high-resolution camera specifically for viewing the capillaries, offering a clear and convenient method for observing the melting process.
• Digital Precision: Temperature readings are provided via a 4-digit, 7-segment LED display, offering a high digital readout resolution of $0.1,^{\circ}\mathrm{C}$.
• Uniform Heating System: The apparatus features a standard silicon oil-bath environment heated by a special oil immersion heater. Uniform temperature distribution within the oil-bath is ensured by an in-built magnetic stirrer with controllable speed managed via a front knob.
• Enhanced Observation: Further observation aids include a large magnifier and a glare-free illuminator designed for stain-free viewing.
• Operational Control: An electronic controller allows for the precise adjustment of the silicon oil-bath heating rate. Measurement control is facilitated via 'Start' and 'Stop' switches to record the onset and completion of melting, and a 'Clear' switch to reset the display.
Construction and Function
The apparatus uses the classic capillary tube method, heating the sample indirectly in a controlled oil bath environment. The silicon oil-bath beaker holds approximately 200 ml capacity and is covered with a Teflon cover that features five holes: three dedicated for holding capillaries, one for a boiling point tube, and one for a thermometer/sensor. Temperature is measured using a digital temperature indicator equipped with a PT-100 RTD sensor.
Applications
The Digital Melting Point Apparatus Model 2935 is an essential piece of equipment across multiple sectors:
• Pharmaceutical Industry: Extremely useful for quality control, determining the purity of Active Pharmaceutical Ingredients (APIs), and ensuring materials meet required specifications.
• Chemistry Laboratories: Used for identifying unknown organic compounds and confirming the purity of synthesized substances.
• Research and Development: Aids scientific research by providing crucial physical property data for material analysis and characterisation.
