Description
The Digital Melting Point Apparatus WRS-18 is a sophisticated laboratory instrument designed for precise determination of the melting points of substances. It is widely used in chemical, pharmaceutical, and material science laboratories to assess the purity and identity of compounds.
Key Features:
1. Temperature Range: The apparatus operates within a broad temperature range, typically from room temperature up to 320°C, allowing for versatile applications.
2. Accuracy: It offers high accuracy, with a precision of ±0.4°C for temperatures below 200°C and ±0.7°C for temperatures above 200°C.
3. Digital Display: Equipped with an LCD screen, it provides real-time temperature readings and melting curves for enhanced monitoring.
4. Heating Rate: The device supports adjustable linear heating rates, ranging from 0.2°C/min to 5.0°C/min, ensuring flexibility for different sample types.
5. Capillary Tubes: The apparatus uses standard capillary tubes for sample loading, with specific dimensions for consistent results.
6. Data Output: Some models include USB connectivity for exporting data or connecting to a printer for documentation purposes.
Operation:
– The sample is loaded into a capillary tube and placed in the heating chamber.
– The temperature is gradually increased at a controlled rate.
– The melting process is observed either visually or through an automatic photoelectric detection system.
– The melting point is recorded when the substance transitions from solid to liquid.
The WRS-18 is valued for its reliability, ease of use, and ability to provide accurate and reproducible results, making it an essential tool for quality control and research applications.
