Cryostats
Variants
LN2 Glass cryostats
LN2 bath cryostats (Dewar flasks) are made of borosilicate glass 3.3 in accordance with DIN/ISO 3585 (DURAN) and are designed for use with liquid nitrogen. They are used as single cryostats or as LN2 cooling shields for liquid helium cryostats.
The cryostats are manufactured exclusively to customer order. Changes to dimensions, connections or volumes can usually be made at no additional cost. The LN2 cryostats listed in the table correspond to the most common dimensions and volumes. LN2 cryostats are supplied with opposing viewing strips as standard.
Of course, the cryostats can also be offered with a visible strip or fully silver-plated. The standard cryostats are offered as a pure glass part. For a small surcharge, they can be fitted with a base cap or with a protective aluminum cover and visible strips
LHe glass cryostats
LHe bath cryostats (Dewar flasks) are made of borosilicate glass 3.3 in accordance with DIN/ISO 3585 (DURAN) and are designed for use with liquid helium. As borosilicate glass 3.3 (DURAN) is not helium diffusion-tight, glass cryostats must be designed in such a way that they can be post-evacuated. A glass flange NW 25 with associated clamp and O-ring is used as a standard vacuum connection, so that the connection to the vacuum pump can be made with small metal flange components. On request, a vacuum glass tap or a bonded metal flange can also be offered as a pump flange.
The helium cryostats are manufactured exclusively to customer order. Changes to dimensions, connections or volumes can usually be made at no additional cost. The LHe cryostats listed in the table correspond to the most common dimensions and volumes. Lhe cryostats are supplied with opposing viewing strips as standard. Of course, the cryostats can also be offered with a visible strip or fully silver-plated.
