I've done various experiments with liquid nitrogen and used regular glass thermos bottles and never had a problem with breakage. Tell us what leads you to believe breakage is a problem (like your experiences with glass dewars).
A neat experiment with LN is to take a high intensity red LED and immerse it in LN. Hook it to a variable power supply and use no current limit resistor. At room temp, the forward voltage is about 1.7 volts. In the LN the LED behaves more like a resistor rather than a diode. I got the forward voltage to about 20 volts and 2 amps before it blew (yes 40 watts!). It was extremely bright before it blew. Also, around 10 volts the spectrum shifted from red to yellow. Quite interesting..
