Drug-loaded mesoporous silica/calcium phosphate composites for bone regeneration

Adrian Szewczyk at Department of Physical Chemistry, Faculty of Pharmacy, Medical University of Gdańsk has kindly allowed us to introduce this paper that introduces a study of Drug-loaded mesoporous silica/calcium phosphate composites for bone regeneration.  

Caleva Mixer working in catalyst application for Ethylene and Propylene

Components were mixed with a specialist Caleva mixer to form a homogeneous paste

How can I be sure that the trials and development work that I do will give me comparable results when I need to scale up to production sizes?

Scale up of the spheronization process is relatively well known and understood. All of the Caleva extrusion and spheronization equipment is designed with scale up in mind.Our range of screw extruders have the ability to modify the density of your extrudate when this is important.
  • The smallest extruder we offer is the Caleva Multi Lab (CML) with an extruder attachment designed to work with...

Extrusion–spheronization a promising pelletization technique: In-depth review

Abstract

This review article deals with various aspects of the extrusion–spheronization technique. The first part includes different steps in the production process of pellets such as granulation, extrusion, spheronization, and drying. In the second part, the parameters which can influence the quality of pellets including formulation (moisture content, granulating liquid,excipients, and...

Catalyst Pellets cracked! The strange apple sauce method

Over the past couple of years I have worked with a huge number of chemical engineering teams, trying to crack the optimum base for a catalyst pellet. After hours of trials and research, I am pleased to say, we’ve done it!

The importance of mixing time for formulation development

It is well established and understood that one of the most important factors in the development of a formulation for both tableting and making pellets by extrusion and spheronization is the amount of liquid binder added to the formulation. What is less widely acknowledged is the importance of mixing and the mixing regime used.
