Leakage testing system C870H

massperformancenetwork

Overview
The C870H integrated loss-on-drying testing system uses the gravimetric method and is designed to meet pharmacopeia and industry testing standards for pharmaceutical, food and chemical laboratories. It is intended for routine and high-throughput loss-on-drying and moisture determinations.

Product features
Precise, traceable and convenient measurement

• Independent dual-chamber design separates drying and weighing to prevent high-temperature effects on the balance.
• Automatic sample-weight determination to reduce operator influence.
• High-precision touchscreen electronic balance (German-imported) with repeatability to 0.05 mg.
• Visualized balance operation and traceable data export for audit trails.
• Internal calibration balance for quick removal and easy maintenance.

Safe and compliant

• Automatic test-cup cover opening/closing ensures consistent handling and regulatory compliance.
• Automatic temperature adjustment supports true room-temperature weighing.
• Fully enclosed, zero-leakage test chamber prevents hazardous gas escape.
• Nitrogen circulation and discrete electrical control systems provide dual safety protection.
• Built-in sensors with audible and visual alarms enhance operational safety.

Intelligent and efficient

• Fully automatic gripper handles up to 36 test cups for high-throughput operation.
• Bidirectional rotation control and adjustable number of rotating cups simplify filling and handling.
• Automatic liquid-cooling operations (fill/drain/level detection) reduce manual tasks.
• Drying, cooling and room-temperature weighing are fully automated without human intervention.
• 12.1" medical-grade touchscreen enables standalone operation without a PC.
• Desktop host design saves bench space and adapts to varied laboratory layouts.
• Embedded network port supports remote control and firmware upgrades.
• Professional software supports GMP traceability and multi-level user access; electronic signature aligns with 21 CFR Part 11 (optional).

Testing principle
Mix the sample thoroughly (crush large crystals to < 2 mm if required). Weigh approximately 1 g or the weight specified by the test standard and place the sample into a test cup dried to constant weight under the same conditions. Weigh accurately and, unless otherwise specified, dry at 105 °C to constant weight. Calculate loss-on-drying from the weight loss relative to the sample weight.

Reference standards

• USP, EP, BP, JP, ChP and other pharmacopeias.
• GB 5009.3-2016 and other food testing standards.
• GB/T 6284, JIS K 0068 and other chemical-testing standards.

Applications

Basic applications - Pharmaceuticals: loss-on-drying and moisture content determination for pharmaceutical materials and products.

Extensive applications - Food: moisture and loss-on-drying analysis for food and feed products.
- Chemicals: loss-on-drying testing for various chemical products and raw materials.
