Helping you make better tablets using advanced material testing

Small scale tablet manufacture

For over a century pharmaceutical manufacturers struggled with powder compression problems such as capping and lamination, powder sticking to punch surfaces or die wall, and insufficient mechanical strength to withstand stress in downstream processing. We thought you’d like to know that we have created a new laboratory tablet testing service…

Taking the guesswork out of tablet manufacturing assessments

Most tablet formulations are developed and manufactured on a large scale without any objective assessment of their ability to form tablets, or whether they are adequately lubricated. With the latest tablet presses measuring both of these parameters, as well as a third critical quality attribute (CQA) – punch sticking (or…

Think what it would mean if you could test your tablet materials and know:

Small scale tablet manufacture

1. Your formulation works 2. Your material is the same quality as previous batches   We’re launching a new laboratory tablet testing service to help you predict and avoid manufacturing problems such as over-compaction, capping and sticking. This will speed up your manufacturing process, reduce material costs and save you…

How to reduce the risk of tablet picking and sticking using the Gamlen D series

Authors Michael Gamlen and Dipankar Dey at Gamlen Tableting Limited Summary Poor lubrication results in picking and sticking problems during production. These are one of the most common causes of tablet defects which result in slow running of the tablet press and reduced output. High ejection stress (>5 MPa) is strongly…
