What we do at Vironova

Vironova is a cutting edge Swedish biotechnology company providing comprehensive hardware, software, and services for the analysis of nanoparticles. We specialize in electron microscopy solutions, with a 10-year track record of services to the pharmaceutical industry.

Our product and service solutions are democratizing access to transmission electron microscopy (TEM) based image analysis in biopharmaceutical development. TEM has previously been too costly and complex for routine use in gene therapy, vaccine and drug development. We are currently changing this with powerful, intelligent, automated, user friendly and accessible technology.

Our customer solution enables automated analyses for simplifying the work process, for faster and better-informed decisions to secure robust bioprocessing and final product quality. We have our headquarter and lab in Stockholm, with subsidiaries in London and Boston.

The Vironova solutions

Vironova offers a broad portfolio of solutions to our clients in the biotechnological industry. We started our journey in 2005 with a focus on developing advance software solutions for image analysis, but have since then become a complete provider of transmission electron microscope (TEM) systems, image acquisition and analysis software, and electron microscopy services. A more profound description and presentation of our solutions can be found below. 


MiniTEM is a compact and agile transmission electron microscope system designed for automated nanoparticle characterization. High-resolution images reveal particle morphologies that are transformed into accurate metrics.

Our MiniTEM system provides pharmaceutical organizations worldwide with an advanced semi-automated microscope which helps them to save time and hence frees up their time to do other tasks. It also increases reliability with its objective quantitative data and minimized risk of human error. Further, it enables both experts and non-experts to operate the microscope with less focus on the technology and more on the results itself. Using the system, clients will face a simple workflow all the way from sample preparation to particle analysis.  

The compact system offers an in-house solution where our clients do not have to wait for service providers. No special infrastructure is needed in order to use the system thanks to its profitable design, weight and technology. It is thereby suitable to be placed in traditional process development or analytical laboratories. MiniTEM is controlled by VIAS.

Be sure to book a free demo to see how our MiniTEM system can help your organization in your imaging and analysis processes. You can also request a quote where one of our senior TEM experts will contact you and provide you with more information about the price. 



ViroTEM is an automated, powerful, and versatile TEM system for analysis and characterization of nanoparticles using the Vironova Imaging and Analysis Software (VIAS).

ViroTEM is the system that meets and exceeds requirements in many scientific fields. It is placed in the absolute front line of innovation and provides a solution for modern TEM analyses. 

The microscope is equipped with a dual-camera system, enabling efficient and rapid specimen searching in full grid overview as well as image acquisition in high resolution. The system can be used in various application areas, but it is specially powerful in those biotherapeutic applications involving viral structures.  

If you want to evaluate how our ViroTEM system can be profitable for your organization you can book a free demo. If you are interested in delivery timeline and investment requirements for the ViroTEM-system you can request a quote here.

Vironova Analyzer Software (VAS)

VAS is a FDA 21 CFR Part 11 compliant software used in TEM based image analysis of nanoparticles. VAS can be operated on MiniTEM and ViroTEM but also on other conventional TEM:s.

Analysis of objects in images can be performed using a combination of automatic analysis tools based on mathematical algorithms, and manually operated tools that aid a domain expert in assessing the images. 

Automation is enabled using machine learning, making it possible to set up methods to automatically classify particles. It helps our clients to save up to 12 hours of work on each sample, compared to manual operation.

Vironova Imaging and Analysis Software (VIAS)

VIAS is an intuitive software used by experts and users with with little previous experience to control the TEM, visualize samples, and analyse data.

It is an advanced image analysis tool using pattern recognition and machine learning capabilities to helps users to perform advanced particle characterization, classification and measurements.

VIAS is an imaging and analysis software that controls transmission electron microscopes (TEM) and provides semi-automatic image acquisition as well as subsequent analysis and data presentation. The software can control the MiniTEM and ViroTEM systems.

Electron Microscopy Services (EMS)

Cost-effective, fast and GMP certified Electron Microscopy services (EMS) enabled by the in-house developed Vironova Analyzing Software (VAS) for semi-automated nanoparticle analysis.

Our electron microscope services team are experts in nanoparticles characterization. We have helped our clients with sample preparation, image acquisition, image analysis and reporting since 2009. With our world's first GMP certified lab, we offer unique solutions to our customers.

The report our clients receive includes representative and high-quality electron microscope images, quantitative analysis and a concluding summary with comments from the expert team. You can request example reports here for different particle analyses.


Viral clearance studies

Vironova Biosafety is a contract research organization (CRO) specialized in viral clearance studies for biological drugs. Viral clearance testing performed in Vironova Biosafety´s GLP and BSLIII certified laboratories.

We offer viral clearance studies in BSLII and BSLIII certified cell and virus laboratories. We are compliant with good laboratory practice (GLP) principles and have been GLP certified since 2011.

Our services range from early R&D to market release. Literature-based viral risk assessment is also offered by our experts with extensive scientific and regulatory experience.
