Evaluating Total Migratable Matter for Hot Drink Cup Safety

Product Description

Features

Professional

As an innovator and leading manufacturer, Labthink is dedicated to development of testing instrument for determination of migration and non-volatile contents, which is highly-integrated, automatic, precise and harmless.

• Integrated testing process with evaporation, drying and weighing all-in-one instrument, which can be used for determination of migration and non-volatile contents with trichloromethane, acetic acid, ethanol, n-hexane and many other reagents.
• Harmless testing process. The evaporated reagent will be collected and processed through special gas pipes, without requiring additional gas handling systems in laboratory.
• High efficiency reagent recycling function makes it possible to recycle 90% Note1 of n-hexane without introducing extra foreign matters (e.g. bath water).
• The testing process is automatic without human intervention, which can protect the operators from the hazardous gases and guarantee the safety of operators.
• Automatic testing process. With precise automatic weighing system, operating errors can be minimized and constant weight can be obtained effectively.
• Precise testing process. Specially designed constant temperature chamber and weighing system can guarantee the testing accuracy.

High Efficiency

High-efficiency and automatic design minimize the human operation. With advanced technology, the instrument supports simplified test method, testing process and combination of tests.

• Worlds leading fast evaporation technology can reduce the evaporation time by heating the reagent to the status most close to boiling.
• The test chamber can be opened and shut automatically. The airtight test chamber makes the operation safe and simplified.
• With gas balancing technology, the concentration of evaporated reagent can be reduced quickly, which improves the evaporation efficiency and operating safety.
• The testing process is efficient with flexible and professional process parameters as well as multiple test modes including proportional mode, standard mode, differential mode and fast mode, etc.
• The instrument is equipped with 9 working stations, with independent test parameters, process data and test results.
• Labthinks exclusive extended working station mode (optional) supports 9 to 90 stations of multiple testing instruments Note3.

Intelligent

The instrument is embedded with Labthinks latest operating software, which is featured with user-friendly interface, intelligent data processing, strict user management and secure data storage. It also supports Labthink exclusive DataShieldTM Note4 (Optional) which provides the users with safe and reliable management of test data and test reports.

• Test data can be displayed in various forms including curves and data list
• Test data will be saved and encrypted in a unique way so that all the test information will be saved securely and reliably and protected from being tampered
• Various forms of test data can be searched, exported and printed out

Test Principle

Total Migration

The specimen shall be soaked in the solution which is simulator of various food. When the solution is evaporated to dryness, the total migration of non-volatile contents can be measured and calculated.

Non-volatile-matter Content

The specimen shall be soaked in standard reagent. When the reagent and blank liquid bath are evaporated to dryness, the total weight of non-volatile-matter contents can be obtained by comparing with the blank liquid.

Test Standards

ISO 759-1981, GB 31604.8-2016, GB/T 9740-2008, YBB00342002-2015 and YBB00132002-2015, etc.
