    Type KGZ LHe Glass Cryostate With LN2
    Cooling Shield And Aluminium Cover

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 gluedon metal flange can be delivered as a pump flange. The top flange of the cryostats is a Schott flange with an O-ring groove.

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.For a small additional charge, we can equip them with a bottom cap or with a aluminum protective cover and viewing strip. For a small additional charge, we can equip them with a bottom cap or with a aluminum protective cover and viewing strip.
