Pre-Compression 8 Station Laboratory Rotary Tablet Press Machine 80KN
Purpose-built for pharmaceutical formulation scientists and R&D teams, this 8 station rotary tablet press features an integrated pre-compression system that mimics production-scale compression behavior. The dual-stage compression process de-aerates the powder before final compaction, delivering tablet properties that reliably predict scale-up performance. Ideal for powder characterization, formulation screening, and clinical trial material production.

FAQ - Formulation Development Tablet Press
Q: Why is pre-compression important for formulation development?
Pre-compression de-aerates the powder bed before final compaction, eliminating capping and lamination defects that often mask true material behavior. The resulting tablet density and hardness data more accurately reflect what will be achieved on production-scale rotary presses.
Q: How much material is needed for a development run?
For preliminary compressibility screening, as little as 50g of formulation can produce enough tablets for basic characterization. A full development batch typically requires 200-500g depending on the number of compression parameter combinations being evaluated.
Q: Can shaped tablets be produced for development purposes?
Yes. Optional shaped tooling sets (oval, capsule, triangle, convex, concave) are available. Shaped tablets up to 23mm maximum length can be compressed, making this press suitable for developing specialty dosage forms.
