C840H Integrated Evaporation Residue Testing System

C840H Integrated Evaporation Residue Testing System is designed and produced based on the principle of gravimetric method measurement and testing standards for plastic packaging and chemical reagents, etc. It is suitable for the determinations of evaporation residue of food or pharmaceutical packaging, total migration of food contact or pharmaceutical contact materials or products, and evaporation residue of chemical reagents and purified water.

Characteristics^{Note 1}

Traceable Data

• Equipped with Labthink’s latest fully automatic gripper that can simulate human hands to realize rapid moving and weighing of 25 test cups.
• Dual-chamber design realizes separation of evaporation and weighing in separate chambers to avoid the influence of high temperature and high humidity on the scale.
• High precision electronic scale with a repeatability up to 0.05mg.
• Precision scale is easily visible through the viewing panel, can be calibrated and traced with a standard material(weights) for data traceability.
• The scale can be quickly disassembled for maintenance and calibration.

Safe & Compliant

• Fully-closed, zero leakage water bath avoids harmful gas overflow.
• Water fill and drainage of the water bath are automatic and the liquid level is automatically detected.
• Rapid liquid cooling system quickly achieves room temperature weighing.
• Nitrogen purge cycling and independent electrical control system are safe for tests of flammable, explosive or toxic gases which may be released from test material.
• Highly efficient reagent collection reduces environmental pollution.

Intelligent Control

• 12.1" medical-grade touch screen user interface, the instrument is operated independently without a computer.
• The instrument mainframe adopts a desktop design to save space.
• Water bath automatically moves in and out of the chamber and automatically closes the lid for convenient operation.
• Water bath evaporation, drying, cooling and weighing at room temperature are completed automatically.
• The instrument is equipped with various kinds of sensors with sound and light intelligent reminders for operator safety.
• The instrument is embedded with a network port and can be connected to the Internet for remote control and upgrading.
• Professional software meets GMP requirements for data traceability and the needs of the pharmaceutical industry.
• Multi-level operation authority management for users can be configured on demand.
• Electronic signature is designed as per standard requirements of 21 CFR Part 11.

Testing Principles

• Total Migration

  The sample is soaked in the solution which is chosen to simulate different foodstuffs. When the solution isevaporated and dried, the total migration amount of non-volatile matter can be obtained.

• Non-volatile Matter

  The sample is soaked in a solution as required by the various standards. After the soaking solution and blank solution are evaporated and dried, the total weight of non-volatile residue is obtained by comparing with the blank solution.
