Sinkers (6/pk) (wt 1.3 g; 9.5 mm x 25 mm capacity)

The choice of sinker or capsule weight depends on the type and size of the dosage form. The sinker should not occlude the surface of the dosage form more than necessary because of the risk of affecting the dissolution rate. Sinkers are available coated or uncoated. PTFE (Teflon) coated sinkers work well with magnetic retrievers whilst uncoated type 316 stainless steel sinkers are more durable. Care should be taken to ensure that direct contact of stainless steel with the dosage form does not cause interference with the active ingredient
