Melting Point Apparatus – ToronMPA™ 200
Melting Point Apparatus – ToronMPA™ 200
Melting Point Apparatus ToronMPA™ 200 is a video-based system designed for reliable melting point work in QC and research labs. The instrument uses semi-automatic detection and provides repeatable melt-point results through controlled heating programs and documented observations. Features such as audit trail and electronic signature are available for documentation needs, including workflows aligned with electronic record requirements.
ToronMPA™ 200 combines precise temperature control with a video camera to simplify visual confirmation during melting point testing. It operates from room temperature to 400 °C with 0.01 °C resolution, supporting controlled ramps when melt transitions happen quickly.
PID-based closed furnace control helps maintain stable heating behavior and consistent conditions between runs. A programmable temperature profile supports up to 10 segments, helping labs run repeatable methods across different materials.
The system is designed for daily lab workflow with touch-screen operation, stored methods, and exportable reports. Results can be printed through supported printing modes and exported as PDF and Excel for reporting and traceability. Multiple interfaces support data transfer in common lab setups, including Wi-Fi and RJ45.
Melting Point Apparatus – ToronMPA™ 200 Applications
- Pharmaceutical research and QC: Melting point and melting range results help confirm material identity and detect purity shifts for APIs and excipients. Video observation supports visual confirmation when investigating out-of-spec behavior or method variation. The four-sample batch format supports routine checks without slowing daily throughput.
- Chemical manufacturing and incoming inspection: Crystalline chemicals often show measurable melting range changes when composition or contamination shifts. Controlled heating programs and consistent furnace behavior help compare lots under the same settings. Semi-automatic detection supports fast screening when paired with a defined SOP.
- Food, flavors, and fragrance solids: Many organic solids used in formulation have characteristic melting transitions that affect handling, storage, or processing. Standardized ramp profiles support internal benchmarks and batch comparisons. Video makes melt behavior easier to confirm without microscope-based viewing.
- Dyes and other organic crystalline substances: Dyes and specialty organics commonly use melting behavior as a screening tool in development and routine checks. Clear video observation supports documentation and operator-to-operator consistency. Repeatable ramps help maintain comparable results across shifts and labs.

Theory and Method
Melting point testing measures the temperature or temperature range where a solid transitions into a liquid under controlled heating. A sample is placed in a capillary tube and heated using a defined ramp rate, then melt onset and the clear point are observed or detected. Pharmacopeial and ASTM approaches emphasize consistent sample preparation, controlled heating rate, and verification using suitable reference materials.
ToronMPA™ 200 uses video observation to show the melt process clearly while a PID-controlled, closed furnace manages the heating profile. The system supports segmented temperature programming so labs can match different material behaviors and SOP requirements. Semi-automatic detection and stored methods help keep execution consistent across operators.
