Overview The C870H Integrated Loss on Drying (LOD) Testing System is a gravimetric instrument designed for loss-on-drying and moisture content determination in pharmaceutical, food and chemical industries. It is built to meet pharmacopoeias and relevant industry testing standards and is intended for routine laboratory and QA/QC use.
Product FeaturesPrecise, Traceable, and Convenient Measurement- Independent dual-chamber design separates drying and weighing to eliminate high-temperature effects on the balance.
- Automatic sample-weight detection reduces operator variability.
- High-precision touchscreen electronic balance (German-made) with repeatability to 0.05 mg.
- Visualized balance operation and full data traceability.
- Internal calibration balance for fast removal and straightforward measurement.
Safe and Compliant: Standardized Processes for Safer Operation- Automatic opening/closing of test cup covers to ensure compliant sample handling.
- Automatic temperature adjustment to enable true room-temperature weighing.
- Fully enclosed, zero-leakage test chamber to prevent hazardous gas emission.
- Nitrogen circulation and discrete electrical control systems provide dual safety protection.
- Multiple sensors and audible/visual alarms enhance operational safety.
Intelligent and Efficient: Fully Automated Process- Fully automatic gripper handles up to 36 test cups for rapid, repeatable movement.
- Bidirectional rotation control and adjustable rotating cup count simplify filling workflows.
- Automatic liquid cooling (fill/drain/level detection) reduces manual interventions.
- Drying, cooling and room-temperature weighing are fully automated without operator presence.
- 12.1" medical-grade touchscreen enables stand-alone operation of the instrument host.
- Desktop host design saves bench space and fits various lab layouts.
- Embedded network port supports remote control and firmware/software upgrades.
- Professional software supports GMP data traceability and multi-level user access; electronic signature designed per 21 CFR Part 11 (optional).
Testing Principle Mix the sample thoroughly (crush large crystals to
