Melting Point Cole Parmer MP-250D-P

Melting Point – Accurate Determination of Material Purity and Quality

Melting Point Cole Parmer MP-250D-P is an essential laboratory instrument used to determine the precise temperature at which a substance changes from a solid to a liquid. This measurement is crucial in research, pharmaceuticals, chemical manufacturing, and quality control because the melting point of a substance is a key indicator of its purity and chemical identity.

From analyzing raw materials to ensuring the consistency of drug formulations, melting point determination plays a vital role in maintaining laboratory standards and regulatory compliance.

What Is Melting Point?

The melting point of a substance is the temperature at which its solid and liquid phases exist in equilibrium. Determining the melting point provides:

• Purity Assessment – Impurities usually lower and broaden the melting point range.

• Identification of Substances – Each compound has a characteristic melting range.

• Quality Control – Confirms that products meet industry and regulatory standards.

Types of Melting Point

1. Capillary Tube Melting Point Apparatus

   • Uses a small sample packed into a thin capillary tube.

   • Traditional, simple, and cost-effective method.

2. Digital Melting Point Apparatus

   • Provides automated temperature control and digital readouts.

   • Ideal for high-precision lab applications.

3. Automatic Melting Point Apparatus

   • Fully automated detection and documentation of melting points.

   • Increases efficiency for high-throughput laboratories.

Why Use a Melting Point Apparatus?

• ✅ Ensure Product Purity and Consistency

• ✅ Meet Regulatory and Pharmacopoeia Standards

• ✅ Save Time with Automated Analysis

• ✅ Support Research, Development, and Quality Assurance

• ✅ Identify Compounds Quickly and Accurately

How a Melting Point Works

1. Sample Preparation – A small amount of finely powdered sample is filled into a capillary tube.

2. Controlled Heating – The apparatus gradually heats the sample at a defined rate.

3. Observation – The point at which the sample starts to liquefy is recorded as the melting point.

4. Automatic Detection (Digital Models) – Sensors or cameras detect phase changes and record results.
