Japanese Basket Sinker (with Certified USP compliant)  

 

Japanese Pharmacopeia Basket Sinker. (This has the same dimensions as the sinker shown in the USP).

 

Fully compliant with the USP specifications and manufactured out of top grade stainless steel using QLA proprietary engineering, this sinker is tough and resilient and will last longer than most Japanese sinkers.

Japanese sinkers feature a hinged end with a clip to allow capsule inertion and maintain security during the test.

The USP states that “A small, loose piece of nonreactive material, such as not more than a few turns of wire helix, may be attached to dosage units that would otherwise float. An alternative sinker device is shown in Figure 2a.”

The alternative sinker is defined with the diagram below. This sinker is designed to work with capsules in such a way that the sinker will not interfere with the dissolution rate. To meet that it is important that the spaces between the bars are carefully regulated to ensure a consistent and reproducible flow dynamic.
