Front Components

The sample chamber, located on the top panel, is where the sample cup is placed for analysis.

The sample chamber should remain capped except when inserting or removing a sample. When left uncapped, water vapor adsorbs on the inner surface of the chamber or the chamber temperature becomes unstable; either condition can affect analysis results. If water vapor accumulates in the chamber, the pycnometer must be purged.

The standalone control module, often used for the Glove Box pycnometer, does not contain a sample chamber. See Glove Box.
