A retractable specimen holder tip protects the specimen during transport. An optimized Dewar design is positioned at a fixed, tilted angle with respect to the axis of the holder, providing a means of continuously cooling the specimen irrespective of the high tilt angle and amount of liquid nitrogen present in the vessel.
