Free, open-source software for microscopy data analysis and visualization.
Gwyddion is a free, open-source software tool for analyzing and visualizing scientific data, particularly data from microscopy and other imaging techniques. It is primarily used for analyzing and processing images and data from scanning probe microscopes (SPMs), such as atomic force microscopes (AFMs) and scanning tunneling microscopes (STMs), but it can also be used for other types of data, such as images from optical microscopes and spectroscopic data. Gwyddion includes a wide range of features and tools for tasks such as data visualization, data analysis, image processing, and curve fitting. It is particularly useful for tasks such as surface characterization, particle sizing, and imaging and analysis of nanostructures. Gwyddion is available for Windows, Linux, and macOS, and it can be downloaded from the Gwyddion website. It is developed and maintained by a community of volunteers, and it is distributed under the GNU General Public License (GPL).

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.
We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.
We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Yes. Every verified supplier states which service partners cover the instrument, and we list that alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
