Using an Oil-Free Air Compressor
When neither house air or compressed air from a gas cylinder is available, you can use an oil-
free air compressor. An air compressor should require the same connections as those
described above for a house air supply. Laboratory air compressors typically have either hose
barb connections or ¼" NPT connections. Since air compressors typically have an internal
regulator, a line regulator is unlikely to be needed.
WARNING! The air compressor must be oil-free. This feature is typically noted on the
specification sheet from the supplier. Failure to supply oil-free air to the
ImageXpress Pico system may damage the instrument and void the warranty.
An oil-free compressor can be purchased from many vendors, including Cole-Parmer
(www.coleparmer.com).
