DENSsolutions

DENSsolutions is a Netherlands-based technology company that develops in situ electron microscopy solutions, turning transmission electron microscopes (TEM) and scanning electron microscopes (SEM) into what the company describes as a nanotechnology lab. Founded in 2012 and headquartered in Delft, the company supplies advanced MEMS-based sample carriers and systems that allow researchers to observe materials under realistic conditions — cooling, heating, biasing, gas and liquid environments — while imaging at the nanoscale. The product portfolio spans in situ TEM systems such as Wildfire (ultra-stable MEMS heating up to 1300 °C), Lightning (electrical biasing and Joule heating), Lightning Arctic (cooling, heating and biasing from cryo to hot), Climate ∞ (controlled gas environment with heating and biasing) and Stream ∞ (liquid-flow cell with integrated biasing and heating). For the SEM, the company offers FireBolt (heating and biasing) and HydroBolt (advanced liquid solution). Sample preparation and cryo-EM are addressed by the FIB Stub and CryoSilico MEMS-based cryo sample carrier, while the Impulse and Nexus software packages provide real-time experiment control, logging, data integration, analysis and visualization. DENSsolutions positions itself as a partner for in situ electron microscopy research, serving universities, research institutes, and industrial and applied-research laboratories worldwide. Its stated purpose is to empower researchers with tools to visualize and understand atoms, unlocking insights for breakthroughs in materials, semiconductors, pharmaceuticals and life sciences. The company emphasizes state-of-the-art technology, user-friendly software and dedicated support across the workflow from sample management to data analysis. Recent releases highlighted by the company include Infinity Light, an optional add-on bringing light stimulus to the Climate and Stream Infinity systems, and two new SEM platforms — FireBolt for heating and biasing and HydroBolt for liquid and electrochemistry studies. The company remains privately held and is not known to be listed on a public stock exchange.

DENSsolutions was founded in 2012 and is headquartered in Delft, Netherlands. The company built its business around in situ electron microscopy, developing MEMS-based sample carriers and systems that allow researchers to observe materials under realistic conditions inside electron microscopes. Its stated mission is to empower researchers with tools to visualize and understand atoms, unlocking insights that lead to groundbreaking solutions. Over time, the company expanded its portfolio from heating and biasing capabilities toward a broader set of environmental stimuli. The in situ TEM line grew to include Wildfire for ultra-stable MEMS heating up to 1300 °C, Lightning for electrical biasing and Joule heating, Lightning Arctic for cooling, heating and biasing from cryo to hot, Climate ∞ for controlled gas environments with heating and biasing, and Stream ∞ for liquid-flow experiments with integrated biasing and heating. The company also extended its reach into the scanning electron microscope with FireBolt for heating and biasing and HydroBolt for advanced liquid and electrochemistry studies. Beyond the microscope stages, DENSsolutions developed supporting products for sample preparation and data handling. The FIB Stub supports reliable FIB lamella preparation for in situ chips, while CryoSilico provides a MEMS-based cryo sample carrier for cryo-EM with autoloader compatibility and graphene-coated membranes. On the software side, Impulse offers real-time experiment control and logging, and Nexus integrates recordings from the microscope and logs from stimuli hardware into a single project aligned on a shared timeline, with built-in Python scripting for analysis. A notable recent development was the launch of light stimulus for the Infinity platform and in situ SEM. Infinity Light is an optional add-on that brings light to the Climate and Stream Infinity systems, while FireBolt and HydroBolt brought heating, biasing and electrochemistry capabilities to the SEM. The company describes its technologies as trusted in academic and industrial labs worldwide, serving universities, research institutes, and industry and applied research. Its purpose connects to applications from energy efficiency to medical advancements and pollution reduction, enabling observations in realistic environments for breakthroughs in materials, semiconductors, pharmaceuticals and life sciences.
