CTVM is a recognized specialist for its three fields of expertise:
Our experience that dates back to the long history of SVT has given us a recognized expertise amongst the industry and labs for many years. Our main application markets are in the fields of high-technologies, in particular in the high-vacuum, high-energy physics, chemistry and electronics
Being one of the few European manufacturers specialized in the traditional craft of glass blowing and glass to metal assembly we accompany our customers in the manufacturing of components made of scientific and technical glass, as well as hermetic glass-to-metal assemblies.
CTVM is in a continuous search for innovation and new skills to be added to its production capabilities. Consequently we are your partner of choice and trust for your projects.
CTVM scientific glass blowers have built a unique expertise in glass to metal assembly, but they also use furnace glass sealing techniques
Alongside glass work, CTVM has developed a genuine capability in the manufacturing of filaments and metal grids, as well as Bayard Alpert ionisation gauges. This unique know-how is the reason for established partnerships with prestigious research facilities such as CERN, CEA or Max Planck Institute...
CTVM takes advantage of its experience to offer faultless product quality which is a key factor for a large number of our customers in the selection of suppliers.
CTVM has been relocated in Collegien – nearby Euro Disney – since October 2014 in the new factory of its sister company Microcertec – a specialist in technical ceramics and precision grinding. This new facility was built with the latest standards that make it possible to comply with the most demanding quality criteria for our staff and production.
Our team of glass blowers processes borosilicate glass, sealing glass and quartz with glass blowing lathes, on benches or in furnaces. CTVM can seal the following metals to glass: Kovar (or Dilver P1) - borosilicate glass 3.3, stainless steel – quartz, Kovar (or Dilver P1) – Schott electronic glass 8250, stainless steel - borosilicate glass 3.3.
We have the technical capabilities and equipment for resistance and TIG welding, electrical testing and leak detection to comply with your quality requirements.
Our quality system is ISO 9001: 2015 approved
