When using the Mojonnier mixture of solvents, a black residue may build up on the bottom of the vessel. If this coating becomes too thick, an "Overtemp Fault" "<Enter>" may occur. The black residue can be cleaned using a drill with a long-shafted...

This can occur with samples that are very low in fat. Moisture left in low-fat samples after extraction is the issue. As AOCS Procedure AM 5-04 indicates, when the Filter Bags are removed from the Extractor, they should be placed in an oven at 100...

Petroleum ether is the most common solvent recommended for use in XT Extractors. Many other solvents will work depending on your objectives but may require upgrades to the method or instrument for them to run effectively. Hexane, for example, will...

A "Low Pressure" error occurs when the vessel does not have at least 3 psi after 13 minutes. Possible Causes: (1) The lid was not tight. You do not have to over tighten the lid, but it needs to be snug. Usually, a finger tight + 1/4 turn is adequate...

The solenoid will become hot if the valve open check box is left checked. Normal valve openings are very brief and within a range of 10-1000 milliseconds, which does not cause the solenoid cylinder to get hot. If the Open Valves button is clicked or...

There may be a problem with the radio frequency (RF) chip attached to the circuit board. This is a dark green/blue colored chip with a black antenna. Refer to RF Service Procedure Chip and Board Replacement (RFS013) for help in identifying the part...
