FM-10, FM-20, FM-30

Metal cryostat is our base product of high reliability, built with the technology and knowhow on metalwork, welding, vacuuming, and cryogenic insulation.
Most of the products are designed and manufactured individually to customerfs requests.
Cryostats combined with small cryocoolers are among our products.

Liquid nitrogen shield (further reduction of helium consumption)

FD-730, FD-1000

Our composite cryostat is made of GFRP and aluminum, the former material used for the horizontal room-temperature bore and the liquid helium tank, and the latter material for its outer vacuum container.
Niobium-made superconductive magnetic shield is built within.

Developed for PTB (Physikalisch-Technische Bundesanstalt) in Germany for the measurement of biomagnetic signals from small animals.
