Compound Dissolution

Compound Dissolution, Resolution, and Thawing

Primary dissolution of compounds, thawing, and resolution of precipitated compounds is a use of AFA™ that is gaining wide acceptance in the compound management community.

Current dissolution technologies are either inadequate or have significant drawbacks compared to AFA. This is illustrated in the table below:

To date a large amount of data has been generated on the application of AFA in compound dissolution. We have included a video to illustrate this; however data is also presented below in comparison to a microplate Sonicator. The data was analyzed using quantitative liquid chromatography.

A number of examples of compound dissolution/ resolution are included as video downloads here. If your particular tube plate is not shown, please contact Covaris. To date many new tube / plate types have been shown to work well, as illustrated in the following videos:

The video showing 500mg of sucrose was conducted on a sample dried into a 4ml at 70°C for a week!
