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!
