Distributed in Australia by Particle & Surface Sciences , AccuPyc II 1340 series pycnometers are fast, fully automatic devices used for high speed and precision volume measurements and density analysis.

These pycnometers are suitable for a range of applications which include:

  • pharmaceuticals
  • coatings
  • calcination
  • ceramics and powder metallurgy
  • rigid cellular plastics
  • plastic films
  • slurries
  • organic chemicals and polymers; and
  • blending of materials.
Capable of performing volume measurements and density analysis on a wide variety of powders, solids and slurries with volumes from 0.01 to 350 cubic centimetres, these instruments complete most sample analyses in less than three minutes.

A simple calibration process allows the user to easily determine the instrument sample cell and expansion chamber volumes using a traceable standard value. After calibration, the cell and expansion chamber volumes are stored automatically.

Sample mass can be directly input from an analytical balance through an RS-232 port.

A unique run precision feature works to increase the precision of analysis results by reporting data from five consecutive volume measurements that are within a user specified tolerance.

This feature allows early termination of analysis, thereby decreasing the number of cycles needed for accurate results.

The AccuPyc II 1340 pycnometer is supplied with an integrated control and density analysis module. For those who require high throughput, analysis modules are also available in a single unit configuration, allowing users to attach up to five additional analysis modules to a single controlling unit.

Each module has its own gas connection. In addition, each module can contain a different size sample chamber.

USB ports on the rear panel of the control module allow for connection to a printer for the output of density analysis and calibration results or to a keyboard for alphanumeric character input.

The USB port is also used for installing software upgrades.

Users can email reports, send data on volume measurements to a web browser for archiving or interface with the AccuPyc II 1340 Windows application through an Ethernet port on the rear panel of the control module.

Level measurements on these pycnometers can be further optimised with options such as:

  • MultiVolume Option Kits for density analysis of a variety of sample sizes in one analytical module
  • measuring of open- and closedcell foam materials in accordance with ASTM method D 6226
  • temperature-control versions that allow analysis at user-selectable temperatures; and
  • glove box model which separates the control and analysis modules, allowing analysis in controlled environments.
