Pascal 240 Porosimeter

Thermo Scientific* Pascal 240 is a medium pressure mercury intrusion porosimeter. It takes over the porosity experiment after the low pressure test is done by the Pascal 140. Pascal 240 runs experiments from atmospheric pressure up to 200 MPa thus characterizing materials with a porosity ranging from 0.0074++ upto 15++ pore dimension.
The Pascal 240 is the versatile, medium-pressure porosimeter module. Its large autoclave can allocate small and large volume sample holders thus it is particularly suitable for testing high porosity samples or heterogeneous materials. It is mainly addressed to soil and rocks investigations, building materials (cements, concrete, bricks and tiles), healthcare (cosmetics, pharmaceuticals) just to mention the most common fields and, in any case, for all those samples showing pores larger than 0.0074µ.
Alert: The Pascal 240 uses mercury as intrusion liquid. Mercury is not supplied by Thermo Fisher Scientific. Mercury is a hazardous material thus should be handled with the same care that any other hazardous laboratory chemical is given. It is strongly recommended to check and conform to specific regulations and recommendations for the use of mercury for each country.

The Pascal 240 incorporates the P.A.S.C.A.L.  method for pressurization that allows the fastest speed of analysis combined with highest accuracy. The pressurization system exploits a specifically designed reversible pump and a new type of pressure multiplier featuring unmatched small dimension. This combination and the P.A.S.C.A.L. approach provide high precision experiments assuring that the pressure data (from which the pore size is calculated) are perfectly equilibrated with the intruded mercury amount (from which the pore volume is measured). The Pascal method is fully automated thus no prior knowledge of the material is required.

  • P.A.S.C.A.L. method of pressurization (Pressurization by Automatic Speedup and Continuous Adjustment Logic) combines the stepwise and intrusion rate equilibrated modes
  • Proprietary algorithm cuts off dead times during the analysis improving the experiments throughput (saves run time compared to other methods)
  • Can work also in continuous scanning mode
  • Extreme high resolution curves with up to 2500 experimental points in each pressure range (up to 4000 points for a complete porosity spectrum) showing a volume resolution of 0.1μL
  • Pascal porosimeters are modular, choice of pressure ranges up to 0.4, 200 and 400MPa (or a combination of them)
  • Pascal porosimeters modules are bench top, with unmatched small footprint
  • Pascal porosimeters come with comprehensive online control software featuring real time display of intruded volume and/or pressure in function of time
  • Data versus time can be exported in a text file for further reprocessing (i.e. kinetic studies)
  • Includes data reduction with real blank correction, compressibility correction, pore and particle size determination (Mayer-Stowe), span evaluation, fractal dimension, tortuosity, permeability and frost resistance factors, graph overlay and comparative results tables among several experiments
  • Easy and customizable reporting and full data export compatible with most common spreadsheets
Includes:
  • Two sample holders
  • Absolute pressure sensor
  • Dielectric oil for high pressure
  • Control and data reprocessing software
  • Instruction manuals

Required Accessories: The Pascal 240 requires a sample preparation unit to degas the sample before the analysis and to fill the sample holder with fresh mercury. The sample holder preparation unit can be either the Thermo Scientific Pascal 140 or the Duplex Dilatometer filling device.

Compatible with:
  • Pascal 140 low pressure module (to extend also the porosity range investigation) or Duplex Dilatometers Filling device
  • Mercury cleaning kit permits to clean and re-use mercury for a long time reducing costs associated to recycling
  • Calibration kit and certified reference materials to control the instrument accuracy and re-calibration

Compliance: ISO15901-1

Certifications: CE certification, PED (Pressure Equipment Directive 97/23/CE)
