C870M Integrated Loss-on-Drying Testing System

C870M Integrated Loss-on-Drying Testing System is based on the gravimetric method and is designed and manufactured in accordance with pharmacopoeias and testing standards of the food and chemical industries. It is suitable for loss-on-drying testing in the above-mentioned fields.

Product Features^{Note 1}

Precise, Traceable, and Convenient Measurement

• Dual-chamber independent design achieves true separation of drying and weighing, avoiding the influence of high temperatures on the balance.
• Sample weight is automatically determined, avoiding interference from human factors.
• German-imported touch-screen electronic balance with repeatability up to 0.05 mg (optional).
• Visualized balance design and traceable data.
• Internal calibration balance for quick disassembly and easy measurement.

Safe and Compliant: Standardized Processes for Safer Operation

• Automatic cover opening and closing technology for test cups ensures a more compliant testing process.
• Automatic temperature adjustment for true room temperature weighing.
• Fully enclosed, zero-leakage test chamber prevents the leakage of hazardous gases.
• Nitrogen circulation and discrete electric control systems provide dual safety protection.
• The system is equipped with various sensors and intelligent audible and visual alerts for safer operation.

Intelligent and Efficient: Fully Automated Processs, Saving Time and Space

• Equipped with a fully automatic gripper that can mimic rapid movement of 12 test cups.
• Bidirectional rotation control & freely adjustable number of rotating cups simplifies the test cup filling process.
• Automatic operations of liquid cooling system (water filling/draining/liquid level detection) reduce manual operation.
• Drying, cooling, and room temperature weighing are fully automatic and require no human intervention.
• 10.1" medical-grade touchscreen allows the instrument host to operate independently of a computer.
• The instrument host features a desktop design, saving space and adapting to various laboratory layouts.
• The system has an embedded network port, which can be connected to the Internet for remote control and upgrades.
• Professional computer software complies with GMP requirements for data traceability, satisfying the needs of the pharmaceutical industry.
• Multi-level user access control with configurable permissions.
• ? Electronic signature is designed in accordance with 21 CFR Part 11.

Testing Principle

Take the sample and mix thoroughly (if the crystals are large, they should be quickly crushed into particles smaller than 2 mm). Take approximately 1 g or the weight specified in the standard and place the sample in a test cup that has been dried to constant weight under the same conditions as the sample. Weigh accurately and, unless otherwise specified, dry at 105℃ to constant weight. Calculate the loss-on-drying of the test sample from the weight loss and the sample weight.
