About Us

condenZero GmbH was founded 2019 as a spin-off company of the Laboratory for Quantum Matter Research of the University of Zurich in Switzerland. Our field of expertise includes the development and production of scientific instruments and components for research applications in ultra-high vacuum and cryogenic conditions.

Swiss Innovation Challenge

November, 2021

It was an exciting experience to be part of the 2021 Swiss Innovation Challenge. We learned a lot from the mentoring sessions and we are honoured to be selected as the winner of the 2021 edition. This achievement would not have been possible without our support network. We are grateful to all those supporting condenZero in previous years.

Helium management

November, 2021

Our cryo-TEM holder relies on a manually operated helium flow circuit. This circuit is now electronically automated such that the cryo-TEM holder can be operated remotely. This is especially useful for TEM users as the absence of humans near the microscope reduces vibrations and is detrimental to high-resolution measurements. Our remote helium flow controller can, however, be helpful for any flow cryostat. 

InnoBooster, GRS

November, 2021

condenZero is proud and honoured to be supported by the Gebert Rüfstiftung via the InnoBooster program. We trust that this will enable us to consolidate and establish a groundbreaking new line of cryo-TEM products.

CERN BIC & Swiss Innovation Challenge

August, 2021

As a spin-off company, we benefit and absorb valuable knowledge from participating in entrepreneurial support programs. Recently, condenZero was selected to the final round of the CERN BIC program. At the same time, condenZero also made it to the finals of the Swiss Innovation Challenge and was nominated in the life science category. We are excited and honoured by these selections and nominations. 

Lowering helium consumption

July, 2021

While moving forward with the nationalisation of the patent application, condenZero is also making technical progress. Prototyping of cryo-TEM holders aims to meet customer specifications in terms of stability, base temperature and helium consumption. In our most recent prototype iteration, the helium consumption was cut down by 75%. With this fourfold reduction, our cryostats can be operated with sustainable helium flow.

100 fürs Baselbiet

June, 2021

Part of our (sub-contracting) manufacturing will be carried out by Basel-located workshops. The Basellandschaftliche Kantonalbank (BLKB) and the Standortförderung Baselland offer favourable loans through the “100 fürs Baselbiet” program, for which condenZero could qualify.

Venture Kick won

 February, 2021

Today, Venture Kick announced condenZero is a final stage winner! We are greatly honoured by this decision. Certainly this is an important milestone. We are very much looking forward to the next Kickers Camp.


January, 2021

It is with great excitement and honour that we announce our participation in the ESA BIC CH program. We are very much looking forward to developing our connection to space related industries. In particular, we wish to accelerate the use of advanced additive manufacturing technologies for space applications.

Core Coaching

January, 2021

We are grateful to Innosuisse for their decision to help and support condenZero via the core coaching program. On this three-year program, we aim to grow and consolidate. In the first year period, we will be working on our first sales campaign, financial structures and advance our IP strategy.

Bridge Proof-of-Concept

December, 2019

Eleven young researchers were awarded the Proof-of-Concept grant from the Swiss National Science Foundation (SNSF) & Innosuisse. With the project to make a new cryogenics tool for transmission electron microscopy, condenZero is among the selected projects.

Patent Application

February, 2019

While working on a pulsed magnetic field setup for diffraction experiments at SwissFel, Dominik Biscette invented a new type of cryostat. This paved the way for the cryo-TEM development underpinning the activities of condenZero.

Entrepreneur Fellowship

December, 2018

End of 2018, Denys Sutter has been awarded a UZH BioTech-MedTech Entrepreneur Fellowship from the Werner Siemens Foundation to develop a new type of cryo-sample holder for transmission electron microscopy.
