Test equipment to masticate chewing gums, especially medicated chewing gums for the in vitro release of substances from the samples into a surrounding liquid medium.
>Function:
Up and down strokes of the lower jaw in combination with a revolving movement of the upper jaw which provides mastication of the chewing gum and at the same time an adequate agitation of the test medium. The lower jaw with the test cell is moving up and down by a device for vertical movements and the upper jaw is revolving without up and down movements.
For manual sampling, emptying and cleaning process the lower jaw with the test cell can be lowered into the down position and the chewing process stops. The test cell, the upper and lower jaw can be easily removed.
The temperature of the water in the test cell around the media will be controlled by a water circulation system.
