The Pentapyc 5200e and the Ultrapyc 1200e are the ultimate gas pycnometers for measuring the true density and volume of powders, catalysts, pharmaceuticals, ceramics, carbons, building materials, rock core plugs, etc.

The Pentapyc 5200e gas pycnometer permits up to five samples to be loaded and then purged simultaneously. Each of the five samples is then automatically analyzed in sequence with no operator involvement. Balance (RS232), PC (ethernet) and printer (USB) connections are standard. A second USB port allows archiving of results to flash (thumb) drive.

For laboratories with fewer density analysis needs, the single sample station Ultrapyc 1200e gas pycnometer provides the same ease of operation and high performance as the Pentapyc, with the additional option of vacuum purge (vacuum pumpnot included).

Both the Ultrapyc and Pentapyc are available in "-T" versions for use with an
external thermoelectric temperature controller.
