Melting Point Apparatus – ToronMPA™ 100
Melting Point Apparatus ToronMPA™ 100 is a video-based system designed for routine melting point work in QC and R&D labs. It runs four samples at a time, uses high-definition video for clear melt observation, and supports semi-automatic detection for consistent results. The system also supports direct printing and common data export formats for reporting workflows.
ToronMPA™ 100 combines precise temperature control with a built-in video camera so operators can see melt behavior clearly and document decisions faster. The instrument covers room temperature to 360 °C with 0.01 °C resolution, supporting stable ramp control when melt transitions occur quickly.
A PID-controlled, fully closed furnace design helps keep heating behavior steady between runs and operators. Up to 10 programmable segments support repeatable heating profiles aligned with internal SOPs.
Touch-screen operation and stored methods support daily lab workflow, while permissions and audit features support controlled documentation. The system includes four-level permission management, audit trail, electronic signature, and method locking options when traceability is required. Results can be exported as PDF and Excel, with common interfaces such as USB, Wi-Fi, and RJ45 for lab connectivity.
Melting Point Apparatus – ToronMPA™ 100 Applications
- Pharmaceutical QC and research: Melting point and melting range checks support identity screening and purity trend monitoring for APIs and excipients. Video observation helps standardize visual decisions during investigations and training. Four-sample batches support routine checks without slowing the workflow.
- Chemical manufacturing and incoming inspection: Crystalline chemicals can show melting range shifts when composition changes between lots. Controlled ramp programs support lot-to-lot comparisons under the same heating conditions. Semi-automatic detection supports quick screening under defined SOP steps.
- Food, flavors, and fragrance solids: Many formulation solids have characteristic melting behavior that supports internal benchmarks and batch comparison. Video makes the melt transition easier to confirm and record during routine checks. Stored profiles help repeat the same ramp conditions across teams.
- Dyes and other organic crystalline substances: Dyes and specialty organics often use melting behavior for development screening and process checks. Repeatable heating segments help maintain comparable results across different sample types. Video observation supports clearer documentation during method development.

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 typically packed into a capillary tube, heated at a defined rate, and observed for melt onset and the clear point. ASTM and pharmacopeial methods emphasize consistent sample preparation, controlled heating rate, and use of suitable reference materials for verification.
ToronMPA™ 100 uses high-definition video so operators can observe the melting process clearly while the furnace follows a programmed heating profile. PID temperature control with a closed furnace design supports stable ramps and repeatable results between runs. Up to 10 programmable segments help match different SOP needs across diverse sample types.
