Micromeritics TriStar II Plus Surface Area and Porosity System

The Micromeritics TriStar II Plus is a fully automated, three-station surface area and porosity analyser intended for laboratories that require the combination of high throughput and high-quality data. Suited for quality control and research environments, the product can collect up to 1000 data points. Fine details of the isotherm can be observed and recorded, providing high resolution and revealing pore structure details.

The unit contains all the capabilities of the TriStar II with additional hardware and software features. A dewar design and isothermal jacket technology provide many extended hours of continuous temperature control. A stainless steel manifold is corrosion-resistant and designed for highly accurate gas management. A dedicated saturation pressure port allows the measurement of saturation pressure on a continuous basis. The three analysis ports operate simultaneously and independently of one another. A krypton option allows precise measurements in the very low surface area range.

A dashboard monitors and provides access to real-time instrument performance indicators and maintenance scheduling information. MicroActive software gives the user the ability to interactively evaluate isotherm data and reduce the time required to obtain surface area and porosity results. Interaction with adsorption data is direct. By moving the calculation bars, the user is immediately updated with new textural properties. User-selectable data ranges through the graphic interface allow direct modelling for BET, t-Plot, Langmuir, DFT interpretation and more.

Included is an improved ability to overlay files (up to 25), including mercury intrusion data with a single-click file add and subtract feature. A Report Options editor allows the user to define up to five reports with on-screen previews. Python scripting language allows users to develop extensions to the standard report library available within the software application. The instrument also utilises the multi-adsorbate integral equation (Dual DFT) for micropore analyses of carbons.
