When selecting an R&D tablet press, the primary focus should be on versatility and precision. For laboratory or pilot-scale research, prioritize machines with interchangeable tooling (D, B, BB, and BBS types) to test different tablet sizes. Ensure the machine offers adjustable compression force (up to 60kN or 100kN) and independent control of pre-compression and main compression to solve capping or lamination issues. Additionally, look for PLC-based touch screen controls that allow for real-time data logging of filling depth and tablet thickness, which are critical for formulation development.
