condenZero AG

condenZero AG is a Swiss cryogenic and vacuum technology company that develops instrumentation for cryogenic transmission electron microscopy (cryo-TEM). Its core proposition is the use of liquid helium as the cryogen for sample holders, which enables ultra-low temperatures with high thermal stability and rapid temperature cycling — capabilities that matter for researchers pushing the resolution and sensitivity limits of electron microscopy. The company's product family is built around a complete, integrated system rather than a single instrument. The full condenZero system comprises the sample holder, the CORVUS damping stage, the TUBUS helium transfer line, and peripheral equipment for temperature measurement and operation. The liquid-helium TEM holders are marketed under the names GLADIUS, JAVELIN and HASTA. Beyond the TEM holder line, condenZero offers the GALEA universal lab cryostat. In addition to catalogue products, condenZero provides engineering services for customised cryogenic and ultra-high-vacuum (UHV) solutions. According to the company, these services span the entire process from conceptualisation and detailed design through drafting, manufacturing, assembly and installation. This project business targets research facilities with specialised requirements; the company cites work connected with ER-C at Forschungszentrum Jülich and SwissFEL at the Paul Scherrer Institute (PSI). condenZero positions itself at the intersection of cryogenics, UHV technology and electron microscopy — a niche serving universities, national laboratories and large-scale research infrastructures. Its customers are researchers who need stable ultra-low-temperature conditions for world-changing discoveries, as the company frames its mission on its homepage. The company is privately held and, based on available evidence, does not disclose a parent company or stock listing.

condenZero AG is a Swiss company working in cryogenic and vacuum technology, with a focus on instrumentation for cryogenic transmission electron microscopy (cryo-TEM). Public evidence about the company is concentrated in its own product and project documentation and a Wikidata entry describing it as a Swiss cryogenic and vacuum technology company; detailed founding dates, founders and corporate history are not disclosed in the available sources. The company's development path is visible through its product line. Its central technical idea is to run TEM sample holders on liquid helium as the cryogen, which allows ultra-low temperatures with great thermal stability and rapid temperature cycling capability. This contrasts with more common liquid-nitrogen-based cooling and addresses researchers' needs for stable, very low temperatures during imaging. Over time condenZero has built a complete system around that idea. The full condenZero system comprises the sample holder, the CORVUS damping stage, the TUBUS helium transfer line, and peripheral equipment for temperature measurement and operation. The liquid-helium TEM holders are offered under the names GLADIUS, JAVELIN and HASTA, and the company also offers the GALEA universal lab cryostat. This portfolio suggests an evolution from a core holder technology toward a broader, integrated cryo-TEM platform with supporting vibration damping and cryogen delivery. Alongside products, condenZero has developed an engineering-services business. It offers comprehensive engineering services tailored to research projects, with a particular focus on ultra-high vacuum technology and cryogenics, spanning conceptualisation, detailed design, drafting, manufacturing, assembly and installation. The company's projects page cites work connected with ER-C at Forschungszentrum Jülich and SwissFEL at the Paul Scherrer Institute (PSI), indicating engagement with major European research infrastructures. condenZero presents its mission in terms of enabling world-changing discoveries through liquid helium TEM. It serves the cryo-TEM research community with a combination of standard instruments and customised cryo-UHV solutions. The company is privately held according to available evidence, and no parent company, ownership group or stock listing is disclosed in the sources reviewed.
