DNS Content Uniformity Testing System complies with the requirements of content uniformity testing and the fixed quanity examnation. A series of work is automatially done to addition of extracting solvent, addition of internal standart solution, extraction, dilution and filtration.
Tablets, capsules, solid preparations in individual containers
(1) Addition of Extraction Solvent
Seperate vessels (36 pieces) for each sample prevent chemical contamination and raise the accuracy of sample introduction volume.
(2) Addition of internal standart
The part in contact with solvent is used with glass and teflon made syringe pump and is raising the accuracy of solvent introduction vloume.
(3) UV and HPLC Analysis
After pre-treatment, it is possible to analyze with UV and HPLC, or extract into sample vial.
(4) Data analysis and report making
It automatically processes the data analysis, preservation and report making.
Commercial disposable filter of pore sizes of 0.2μm and 0.5μm can be used.
The extraction by stirrer and ultrasonic wave is possible.
The system complies with the requirements of content uniformity testing and the fixed quanity examnation. Troublesome work can be done by unattended operation all night.
A series of work is automatially done to addition of extracting solvent, addition of internal standart solution, extraction, dilution and filtration.
An analysis for on and offline UV and HPLC, data analysis as well as the preparation of a report can be performed.
The full automated Content Uniformity Testing System carries out automatically for washing and drying of the extraction vessels.
