The Versa-Pyc utilizes gas expansion technique and is optimized for accuracy and speed. Both,
Automatic and Manual modes, are implemented in software. The unique design of software
allows the user for defining and carrying out experiments and all data are recorded in text format.

Versatile Gas (Helium) Pycnometer
with extended range of volume (density) measurements.
Versa-Pyc XR™
| The photo above illustrates one possible extension of volume range by using sample chamber adapter and two separate stations. The volume of the station attached to the externally available reference chamber port (EXT REF) can be filled with any suitable object (e.g. metal/glass object) to adjust its volume. Volume of such resulting reference chamber can be calibrated using the sample station and suitable object of known volume, e.g. precisely machined metal rod. Carrying out experiment is the same as in regular pycnometer, except that the sample chamber is external to the instrument. Our novel design allows using the container as a sample holder. |

From R&D to QC applications, the Versa-Pyc is a gas pycnometer of choice for wide
ranges of samples volume measurements. Two built-in reference chambers, (nominal 10
cc and 100 cc), cover the most common range of volumes from fraction of mL to over
100 mL. The range can be easily extended to at least 1000 mL by using auxiliary
hardware and attaching either optional chambers or user-designed chambers
