- Bespoke CVD quartz furnace boats engineered for 2-inch to 8-inch wafers.
Life Sciences & BioPharma at AstraZeneca BioVentureHub (Mölndal)
In the biomedical cluster surrounding Sahlgrenska Science Park and Mölndal's biopharmaceutical facilities, quartz glass is vital for chemical inertness and optical clarity during analytical chromatography and synthesis:
- Deep-UV quartz flow cells for high-performance liquid chromatography (HPLC).
- Zero-leaching ozone-free quartz ampoules for pharmaceutical reference storage.
- Heavy-wall quartz reaction columns capable of withstanding corrosive acid vapours.
Battery Gigafactories & CleanTech Electrification at Hisingen
With major battery and e-mobility technology investments centered across Gothenburg's industrial estates, pyrochemical furnace components play a pivotal role in active material synthesis and thermal testing:
