Pascal Evo mercury intrusion porosimeter rangeInvestigate the porous structure of solid samples quantitatively with mercury pore size analysis. Thermo Scientific™ Pascal Mercury Porosimeters provide reliable information about pore size/volume distribution, particle size distribution, bulk (envelope) density and speciﬁc surface for most porous solids using Pressurisation by Automatic Speed-up and Continuous Adjustment Logic, Pascal.Building on the success of the Pascal range, the new Pascal Evo features enhanced performance and additional software features. Two high pressure models are available together with a Macro pore unit or mercury filling device. Using the P.A.S.C.A.L pressurisation system. All modules feature this proprietary pressurisation procedure that automatically (and easily) determines the correct speed collecting data at the real equilibrium, without any need of expertise or previous knowledge of the sample.
A total of up to 20,000 pressure points can be measured on the intrusion and extrusion cycles on the Evo with increased pressure resolution. The instruments are fully controlled using the software which also allows for external control for maintenance and service issues.
Low cost of use is down to affordable sample chambers (dilatometers) which minimise mercury use, and the dilatometer is always in vertical position in any phase: degassing, mercury filling, low pressure experiment, high pressure experiment. This means that the hydrostatic pressure over the sample is always measured and used to correct the real pressure over the sample, this is particularly important especially at low pressures that is to say with macro and ultra-macroporous materials.
