The large main housing is precision ground from a single piece of high grade material and then optically polished on several of its exterior as well as interior surfaces. Four holes are bored through the housing and honed to a high degree of accuracy and finish. A closed tube, open to the outside only, accepts a thermistor probe used to monitor the temperature of materials inside the chamber. Another precision tube which has one end finely ground to a sharp angled point. This tube is closed to the outside.
Dendritic growth begins at the tip of the stinger tube.
A quartz tube bent to a 90 degree angle and constricted to an hour-glass shape at one point. This tube is used to evacuate the chanber and to fill it with test material. It is then thermally closed off at the point of the constriction. The pump is by far the most complex of the four attachments and is actually an operating piston and cylinder manufactured from 6 separate pieces of synthetic quartz. A metal core is encapsulated under a vacuum process within the quartz and this, after precision cylindrical grinding and lapping to an 8 microinch finish, becomes the piston.
