For a long time, the LabEvent T20 from Weiss Technik was the world’s smallest temperature test chamber with impressive compact space requirements and a test chamber volume of 16 liters. Sale of the device was discontinued at the start of 2025 due to the EU F-Gas Regulation. But now the device is celebrating a strong comeback – with a future-proof CO₂ cooling circuit.
Why CO₂?
The EU’s new refrigerant regulation requires a gradual move away from fluorinated greenhouse gases (F-gases), which are very significant drivers of the greenhouse effect. CO₂ (R744) is an environmentally friendly alternative with GWP = 1, i.e. minimal greenhouse potential. Weiss Technik has managed to integrate this technology into the smallest device of its class – a technical masterpiece.
Technical highlights of the new LabEvent T20
- Test chamber volume: 16 liters
- Temperature range: typically from -30/-40 °C to +130 °C
- Cooling circuit: Co₂-based, conforms with EU F-Gas Regulation, GWP 1
- Areas of application: Research, electronic components, medical technology
- Performance: anticipated 4K/min cool down
Compact, sustainable, high-performance
With the new LabEvent T20, Weiss Technik shows how sustainability and high-tech can be combined in a compact format. For labs, development departments and quality assurance bodies that require high levels of performance in the smallest space, this device is a real game changer.
Market launch & roadshow
Delivery of the new LabEvent T20 is planned for the end of 2025. Before that, the device will be presented in six German cities in the “Brunch & Learn” Roadshow: Visitors will get exclusive insights there into the new technology and can experience the device’s performance and compactness up close and personal.
