cryostats for liquid nitrogen and liquid helium. useable with all cryogenic liquids
Cryostats
LN2 bath cryostats (Dewar flasks) are made from DURAN borosilicate glass 3.3 in compliance with DIN/ISO 3585 and have been designed for use with liquid nitrogen. They are used either as a single cryostat or as an LN2 cooling shield for liquid-helium cryostats. Cryostats are made to order. Changes as to the dimensions, connections or volumes can usually be made at no extra charge. The standard LN2 cryostats come with opposing viewing strips. The cryostats can also be delivered with one viewing strip or fully silvered. Standard cryostats are available in pure glass. For a small additional charge, they can be equipped with a bottom cap or with a aluminum protective cover and viewing strip

The top flange of the cryostats is a Schott flange with an O-ring groove. Changes as to the dimensions, connections or volumes can usually be made at no extra charge. The LN2 cryostats listed in the table correspond to the most common dimensions and volumes. The standard LN2 cryostats come with opposing viewing strips. The cryostats can also be delivered with one viewing strip or fully silvered. Sizes from 2liters to 38 liters
Cryostats are only made to order. Changes as to the dimensions, connections or volumes can usually be made The LN2 cryostats listed in the table correspond to the most common dimensions and volumes. The standard LN2 cryostats come with opposing viewing strips. The cryostats can also be delivered with one viewing strip or fully silvered. Versions with reduced lower diameter
LHe bath cryostats (Dewar flasks) are made from DURAN borosilicate glass 3.3 in compliance with DIN/ISO 3585 and have been designed for the use of liquid helium. Glass cryostats must be designed so that they can be re-evacuated, as DURAN borosilicate glass 3.3 is not helium-tight. The standard vacuum connection used is an NW25 glass flange with clamp and O-ring, which makes it possible to establish the connection to the vacuum pump using small flange components made from metal. Upon request, a vacuum glass tap or a glued-on metal flange can be delivered as a pump flange. The helium cryostats are only made to order. Changes as to the dimensions, connections or volumes can usually be made at no extra charge. The LHe cryostats listed in the table correspond to the most common dimensions and volumes. The standard LHe cryostats come with opposing viewing strips. The cryostats can also be delivered with one viewing strip or fully silvered.

LHe bath cryostats Type KGZ are made from DURAN borosilicate glass 3.3 in compliance with DIN/ISO 3585 and have been designed for the use of liquid helium. The cryostats have an LN2 cooling shield to reduce the heat load on the liquid helium. Glass cryostats must be designed so that they can be reevacuated in the area of the LHe tank, as DURAN borosilicate glass 3.3 is not helium-tight. The standard vacuum connection used is an NW25 glass flange with clamp and O-ring, which makes it possible to establish the connection to the vacuum pump using small flange components made from metal. Upon request, a vacuum glass tap or a glued on metal flange can be delivered as a pump flange. The top flange of the cryostats is a Schott flange with an O-ring groove.
