Product Features

Measure the dissolution of medical packaging materials, food-related materials and other materials of plastics, plant fibers and other materials in different immersion liquids; measure the non-volatile content of various chemical reagents and medicines; measure the evaporation residue and analyze the leaching amount of products .

 

Test principle

Weighing method. Soak the sample with the solution required by the standard. After a specified period of time, remove the specified volume of immersion liquid (or related chemical reagents) and place it in an evaporating dish. The evaporating dish is placed on the water bath in the test box to evaporate; the water bath box releases water, and the test chamber becomes an oven; the evaporating dish is dried; the isolated external water cooling device quickly cools the test box and the evaporating dish; the lifting mechanism and rotating tray in the test box Cooperate, weigh the evaporating dish at intervals, perform constant weight weighing or constant weighing; calculate the mass change of the evaporating dish and determine the amount of evaporation residue or non-volatile matter of the sample.

 

Technical characteristics

l Fully meet the requirements of the standard test: evaporation, drying, cooling and weighing under normal pressure;

l The water bath box, oven, cooling box and weighing box are integrated into the same box, and the desktop instrument reduces the space occupied;

l Independent testing of 23 sample data in a single machine;

l Two drying processes complete 0.3mg constant weight;

l Water bath temperature, drying temperature, weighing temperature can be set, fully digital automatic control;

l The water bath box automatically enters and drains, and the liquid level is judged automatically, and the circulation is clean;

l Indirect heating method of metal plate, no high temperature point in the test box: explosion-proof and flame-proof;

l External water bath cooling (isolated from the inside of the test box), with the internal circulating air, to achieve rapid cooling;

l The world's top MT internal school balance (Mettler-Toledo): internal calibration, no external weight required;

l Patented balance heat and moisture proof technology to ensure the safety and stability of the balance; the analytical balance is integrated in the test box;

l Stop the wind and gas before weighing, the balance is automatically calibrated and cleared to ensure the accuracy of weighing;

l Fully automated test: automatic rotation, lifting and weighing;

l Two test modes of constant weight and constant time to meet different test needs of users;

l Immersion night volume measurement, 2 modes: manual measurement, balance calculation;

l Can specify the corresponding blank sample to simplify the operation;

l Professional exhaust gas condensation recovery device, environmental protection and safety;

l Software functions: full monitoring, real-time recording, graphical reproduction of the test process; power-off data storage; open database (encryptable); printable and outputable PDF, WORD, EXCEL reports in multiple formats (only for pharmaceutical companies in PDF format) .

l Optional modules required by GMP "Computerized System": user management, authority management, data audit tracking and other functions.
