Melting Point Apparatus
Heats a sample packed in a thin glass capillary at a slow, controlled rate and records the temperatures at which it starts and finishes melting. Used for identity and purity checks of APIs and excipients.

Melting point apparatus calibration procedures
Instrument qualification (DQ · IQ · OQ · PQ)
- 01
DQ — Design qualification
Defines the needs: temperature range, ramp rates, number of capillaries, automatic detection and video recording, and data integrity features.
- 02
IQ — Installation qualification
Confirms the correct model, serial number, accessories, software version and a suitable bench and power supply.
- 03
OQ — Operational qualification
Checks ramp rate accuracy and temperature accuracy with melting point reference standards across the range.
- 04
PQ — Performance qualification
Shows the instrument gives correct results in routine use, for example by measuring a reference standard close to the melting points of the materials tested.
Keep every Melting point apparatus in control: usage logs, calibration and maintenance schedules, and automatic blocking of overdue instruments.
