• Working temperature 4 K and 350 K, with a very high temperature stability (e.g. 3 mK by metal cryostats for the cooling of optical sensors).
• Design as pressure vessel possible (also in GRP)
• Liquid charge 250 ml up to 300 liter (in custom design up to 700 liter)
• Cooling capacity 10 to 1300 Wh (35 to 4400 BTU)
• Automatic filling and reliquefaction with sensors for monitoring.

• Low evaporation losses (Nitrogen evaporation rate < 6 % of the liquid volume per day)
• Long vacuum durability
• The leackgae rate for GRP cryostats is typical 9×10^-10 mbar l / s
• HF-noise < 1  % in the range between 10 Hz and 2 MHz
• Magnetic noise < 4 fT / Hz ^-½

For non-destructive material testing position-independent GRP-Cryostats with an adjustable cold-warm distance (z-axis) can be manufactured. In the case of the measurement of lowest magnetic fields (heart and brain diagnostics) a displaceable x-y-position for the sensor is feasible. GRP-Cryostats, e.g. for geological surveys, can be delivered with solid insulation as well.  For the laser based gas analysis with laser diode metal cryostats are needed which have a highly temperature stability of 3 mK at the sensor location.

• First position independent helium cryostat (e.g. for sensor cooling) made of GRP, with exhaust gas cooled radiation shield instead of a LN₂ reservoir. 0.1 W standby heat load corresponds to 3 liter helium a day.
• First LN₂ bath cryostat made of GRP for sensor cooling with a special plug instead of a neck pipe, content 35 liter – a standby vaporisation of 0.9 liter per day corrosponds to a operating time of 35 days.

• For ring cryostates made of GRP, designed as a pressure vessel without insulation on the top, a heat load less than 6 W / m² (depending on the design) is achievable. Such cryostats are suitable for the cooling of HTS componentes.
• The leackgae rate for GRP cryostats is typical 9×10^-10 mbar l / s
