INTRINSIC DISSOLUTION (USP 1087) - "Wood Apparatus"
According to USP chapter 1087, intrinsic dissolution (also called "Wood Apparatus") can be defined as the release rate of a substance under constant surface conditions. It differs from the more conventional USP methods in that only the 7mm diameter surface is in contact with the dissolution medium.
This allows the release of the pure active ingredient (API) or a loose powder to be determined, which is important for understanding the effect when developing new drugs.
The intrinsic set consists of a plate that allows the "die" to be securely accommodated in the press. The stamp is pressed into the "die" with the press in order to press the active ingredient according to the instructions. The "die" with the pressed-in active ingredient, including the stamp, is then screwed onto the shaft with the holder.
We offer compatible sets for many types of dissolution testers, as well as the individual components of the intrinsic sets for individual compilation.
