Thermo Scientific* Pascal 140 is a fully automated low-pressure mercury porosimeter and sample preparation unit. It works from vacuum up to 400 kPa pressure providing fast and reliable porosity characterization from 3.8um up to 900um pore dimension.
The high level of automation of Pascal 140 simplifies the operator's work and assures a very high reproducibility of results. The unmatched analysis speed combined with accuracy and ease of use, make this instrument ideal for any analytical purpose both for quality control and research applications. Industrial sectors like cements, catalysts, ceramics, fertilizers, filters, porous glass, paper, pharmaceuticals and polymers (to mention the most important) will benefit of the reliability of the Pascal 140.
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 0.0074um upto 15um 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 0.0074.
Thermo Scientific* Pascal 440 is the high pressure model of the Pascal mercury porosimeter line working up to 400MPa starting from atmospheric pressure. Pascal 440 can measure pores ranging from 0.0036um up to 15um pore dimension.
The Pascal 440 is developed to meet the sophisticated analytical requirements of laboratories working with new materials in many application fields like, for instance, ceramics, sintered metals, hardened materials and, in general, for all the solids showing porosity approaching the micropore region. Thanks to its unique pressurization speed (the maximum pressure can be reached in as little as 9 minutes!) it is highly recommended also for QC labs where short run times and productivity are priority.
Thermo Scientific* Pycnomatic ATC (Automatic Temperature Control) delivers fast and accurate results for the determination of the skeletal density of solids and powders. Pycnomatic applies the volumetric gas displacement technique and features an integrated temperature control by a Peltier device for best and fastest instrument stabilization and testing speed.
Pycnomatic ATC has a built in multi-volume capability to match the widest number of applications with best accuracy and repeatability. In volumetric apparatuses the reliability in measuring density is also related to the available amount of sample. Depending on the material, user can choose up to five different volume configurations with the Pycnomatic, ranging from 4 to 100 nominal cc capacity sample cells. In addition, up to three different calibrated reference volumes are automatically selected to provide the best accuracy according to the sample volume in use. Pycnomatic is suitable to test any type of powder or solid like cements, pharmaceuticals, soils and rocks, polymers and foams,ceramics and pigments
Thermo Scientific* Surfer sets a new standard for specific surface area and pore size analysis. Surfer applies the principle of static volumetric gas adsorption under controlled conditions of temperature and pressure to determine micro structural properties of solids and powders.
Specific surface area and pore volume pore size distributions are important parameters for the characterization of porous materials as they are directly related to their capacity to react with or dissolve in other substances. Surfer is suitable for any application requiring the characterization of very small pore size, in the range of meso and micro pores. Most common applications are relevant to adsorbent substances like activated carbon and zeolites, but also any type of sample where it is necessary to know the specific surface area and pore dimensions (like alumina, silica, metal supported catalysts, pigments, pharmaceutical powders, etc.).
Thermo Scientific* TPDRO 1100 is a time-saving, high precision instrument designed for the characterization of heterogeneous supported catalysts and reactive solids. TPDRO performs automatically and simultaneously the sample preparation (activation) on a reactor while analyzing another sample in a second reactor, thus saving valuable lab time.
The TPDRO 1100 performs automatically in parallel on two reactors or sequentially on a single one, the catalyst preparation (like oxidation, reduction, saturation with a probe gas, degassing, etc.) and surface reactivity characterization (temperature programmed desorption, reduction and oxidation, chemisorption by pulses of gases and vapors). Thanks to its double and independent pneumatic circuits, TPDRO shortens the total process saving valuable lab time. TPDRO is particularly suitable in industrial catalysis research labs where a high sample throughput is required without compromising accuracy. TPDRO 1100 provides easily and rapidly information like catalyst metal dispersion, metal surface area, metal aggregate size, activation energy, single point BET, acid and basic sites surface concentration.
