Can other solvents besides Petroleum Ether be used in the XT Extractors?

Petroleum ether (PE) is the most common solvent recommended for use in the XT Extractors.  However, other solvents may be used but may require upgrades of certain parts of the instrument in order to function properly. For example, the XT instruments can run with PE, hexane, diethyl ether, ethyl ether (EE), or a modified Mojonnier mix (PE/EE/Abs EtOH 45:45:10) as the extracting solvent. Certain higher penetrating solvents such as diethyl ether and EE require a valve and seal upgrade (SKUs: X55 and X95) for the instrument to function properly. Chlorinated solvents such as chloroform and methylene chloride can be utilized in the instruments. However, we do not recommend using these solvents as they tend to damage the XT4 Filter Bags.
