AccuPyc II 1345

Gas pycnometry is recognized as one of the most reliable techniques for obtaining true, absolute, skeletal, and apparent volume and density. This technique is non-destructive as it uses the gas displacement method to measure volume. Inert gases, such as helium or nitrogen, are used as the displacement medium. Density calculations using the gas displacement method are much more accurate and reproducible than the traditional Archimedes water displacement method.

Autopore V series

AutoPore V – Mercury Intrusion Porosimetry

Class Leading, Proven Performance Establishing a New Benchmark for Operational Safety

The mercury porosimetry analysis technique is based on the intrusion of mercury into a porous structure under stringently controlled pressures. Besides offering speed, accuracy, and a wide measurement range, mercury porosimetry permits you to calculate numerous sample properties such as pore size distributions, total pore volume, total pore surface area, median pore diameter and sample densities (bulk and skeletal).

FlowSorb III

Flowsorb III 2305/2310 Surface Area Analyzer

The Flowsorb III 2305 / 2310 provides single-point and multipoint BET surface area measurements with speed, accuracy, and reliability. Samples having surface areas from 0.01 m2/g to over 1,000 m2/g are easily accommodated.

FT4 Powder Rheometer

The FT4 Powder Rheometer – a universal powder flow tester for measuring powder flow properties and powder behaviour.

The FT4 was designed with one purpose in mind – to characterise the rheology of powders, or powder flow properties. This remains a primary function today, but the instrument, accessories and methodologies have been continuously developed to the point where the FT4 is now considered a universal powder flow tester.

Gemini VII 2390

Gemini VII 2390 Surface Area Analyzer

Unique Design – The secret of Gemini’s unique capabilities lies in the innovative use of sample and balance tubes. These tubes are identical in every aspect, including their thermal environment. The sample and reference reservoirs, like their associated tubes, are physically identical and are initially charged to the same pressure. During an analysis, differential pressure between reservoirs is monitored. This common mode technique assures that any differential pressure is solely due to adsorption by the sample and not to factors that lead to variations in free space during an analysis.

GeoPyc 1365

The GeoPyc employs a unique displacement measurement technique that uses Dry Flo, a quasi-fluid composed of small, rigid spheres having a high degree of flow-ability. The sample is placed in a bed of Dry Flo which is agitated and gently consolidated about the sample. The GeoPyc collects the displacement data, performs the calculations, and displays or prints the results.

  • Highly accurate and reproducible results
  • Fast operation in a small bench-top instrument
  • Fully automated data acquisition and reporting
  • Nondestructive analysis maintains sample integrity
  • Intelligent touch panel for ease of operation and reporting

MIC SAS II

Developed as a direct and improved successor to the widely used Fisher Model 95 Subsieve Sizer (FSSS), the Micromeritics SAS II has improved the FSSS’s performance by offering easy-to-use automated functions together with electronically recorded data.

Sentinel Pro

Dynamic Image/Particle Shape Analyzer

The SentinelPro is a class-leading dynamic image analyzer that is ideal for applications where particle shape, not just the particle size, may be critical information for predicting raw material quality and to maintain a high level of process control.

Particle morphology provides important information regarding the physical shape properties of your sample. It has been shown that shape can affect flowability, dispersion, packing density, segregation, aggregate formation, and microstructure character.

The fully automated SentinelPro is a well-suited research grade instrument or for use in a full production environment where speed, accuracy, and ease of use with its Pass/Fail shape control limits feature can be utilized.
