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…

Making better tablets using a Gamlen D series and manufacturability protocol


Simplify tablet formulation evaluation with a manufacturability protocol

Video illustrates how development of a manufacturability protocol for laboratory use is an important process of developing tablet formulations and improving tablet quality.

The manufacturability protocol developed for use on the Gamlen D series can be used throughout the lifecycle of the product from research to manufacturing, and generates key data to ensure quality on an ongoing basis.

New report reveals PROSOLV® EASYtab to be exceptional material with large capacity for dilution and excellent compaction characteristics

Report by Dr Michael Gamlen Summary The objective of this work was to establish the effect of adding a range of concentrations of ascorbic acid to PROSOLV® EASYtab, a multi-functional tableting excipient. The work was done using the Gamlen D series powder compaction analyser and included a wide range of…

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…

Influence of physicomechanical properties of starches on their tabletability – A multivariate analysis

Out of the six different grades of starches studied PURE-DENT® B830 and SPRESS® B818 showed better tabletability regardless of similar MC and amorphous nature. The better tabletability of these two starches might be attributed to their better plasticization due to loosely bound associated water, and low elastic recovery in the…
