LN2 Glass Cryostats With Head Flange

LN2 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 nitrogen. They are used either as a single cryostat or as an LN2 cooling shield for liquidhelium cryostats.

Cryostats are only made to order. 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.

Standard cryostats are available in pure glass. For a small additional charge, we can equip them with a bottom cap or with a aluminum protective cover and viewing strip.
