The Effects of Solid Particle Containing Inks on the Printing Quality of Porous Pharmaceutical Structures Fabricated by 3D Semi-Solid Extrusion Printing

3D printing pharmaceutical products opens the door to an exciting world of individually tailored drugs, unique for each patient. In this paper the drying process of single and multi-layered printed materials was monitored using the Linkam Imaging Station, monitoring changes in pore size as the 3D printed paracetamol was dried.

Mannitol/l-Arginine-Based Formulation Systems for Freeze Drying of Protein Pharmaceuticals: Effect of the l-Arginine Counter Ion and Formulation Composition on the Formulation Properties...

In this study, Linkam’s FDCS196 was used to freeze dry pharmaceutical formulations to obtain partially crystalline solids. They show that these mannitol/l-arginine-based formulations can be freeze dried in a fast process to produce a viable cake structure.

Multiple approaches to pharmaceutical polymorphism investigation—A case study

In this work, researchers use Linkam’s LTS350 (now LTS420) stage to characterise the physiochemical properties of a pharmaceutical solid compound in four different forms (anhydrous polymorphs (Forms I and II) and two monohydrates (Forms III and IV)) to evaluate its suitability for pharmaceutical development.
