Expand the capabilities of your lab with Atmosphere 210, which offers gas mixing, independent flow control, and low-pressure gas delivery that turns any TEM into an environmental TEM. Featuring the same holder assembly, Clarity software, and in situ workflow as Atmosphere 200, this new product introduces new exciting new gas handling capabilities to your experiment. Updates to Clarity software, coupled with improved manifold and holder hardware enable control of the gas composition, flow rate, and pressure at the click of a button. Optional Clarity Echo software synchronizes all experiment conditions and in situ data with your images and videos, reducing post-processing time by 10x.


  • Mix a wide array of gasses, including H2O vapor for your study

  • Introduce pressurized gasses at realistic flow rates

  • Control flow rate, composition, pressure, and more within Clarity software



Utilizing standard gas mixing techniques to precisely add and mix precise quantities of gas, this update to the Atmosphere system can mix virtually any composition of the three gases connected to your system. This calibration-free method ensures mixture homogeneity and can deliver gasses at pressures ranging from 1.0 Torr – 760.0 Torr and at flow rates ranging from 0.005 mL/min – 1.000 mL/min.

New with Atmosphere 210, Clarity software controls the gas composition and gas flow rate, all within the same, simple user interface you expect.


Now featuring the capability to mix gaseous water, ethanol, and other vapors to your sample, Atmosphere 210 lets you mimic real catalysis environments like never before. Optional accessories allow you to connect your own Residual Gas Analyzer (RGA) to the gas outlet, enabling precise monitoring of the in situ chemical processes. New holder construction reduces thermal drift by 5x while new, chemically inert silica-based gas lines improve experiment accuracy and repeatability.
