3 Flex General Interest

High Resolution, High-throughput Physisorption and Chemisorption Instrument

Recognized as the most advanced instrument in the field for material surface characterization1. The 3Flex has become a crucial tool for providing high resolution adsorption, desorption, isotherms to advance and validate fundamental understanding into development of methodologies and process improvements.

Extend and increase your knowledge.

3Flex permits you to optimize your experimental parameters to gain greater understanding of your material. This is the only available 3-port surface characterization system with the ability to analyze a sample with 3 separate probe gases simultaneously, one on each analysis port,
within a single run.

Extend your range of study.

Go beyond micropore and extend your range of resolution to the ultra-microporous level. The advanced engineered design of the 3Flex permits you to acquire accurate results with a resolution to 10-5 mmHg

Optimize your process.

With 3Flex you gain valuable data to validate your theories and rationalize the design and synthesis of MOFs, zeolites, activated carbons and other products. Utilize the high throughput results of the 3-port mesopore and micropore design of the 3Flex to gain rapid understanding of restrictions or boundaries that may influence or impede your process optimization.

Micromeritics 3Flex Surface Characterization Analyzer is a fully automated three-station instrument capable of high-performance physisorption and chemisorption analyses with superior accuracy, resolution, and data reduction.

Available Models:


3Flex Physisorption

The 3Flex is a high-performance instrument for mesopore and micropore analyses and delivers superior accuracy, resolution and data reduction. All analysis stations can be configured for micropore and are also available with krypton analysis for low surface area materials. A vapor sorption capability is also available. A single 3Flex with its minimal footprint and three configurable analysis stations eliminates costly investment in multiple instruments and additional bench space. MORE

3Flex Chemisorption

Using the chemisorption option, researchers can obtain valuable information about the physical or chemical properties of catalysts, catalyst supports and a variety of other materials. This model can easily switch from chemisorption to physisorption in less than 3 minutes to provide advanced analyses on the active surface area of the sample material. MORE

3Flex TCD

The 3Flex TCD is our newest addition to the expanding capabilities of the 3Flex instrument family. Dynamic chemisorption analyses are available to the user with the addition of an integral thermal conductivity detector. This new feature allows the user to perform temperature programmed reduction (TPR), oxidation (TPO), desorption (TPD), and reduction reactions (TPRx). The 3Flex TCD also has an option for pulse chemisorption analyses which can be performed with manual injections or automatically with the optional injection loop. MORE
