1. A system comprising:
a carrier tray comprising a plurality of ports therethrough, each port having a top edge, a bottom edge, and an interior wall;
a process tube comprising
an annular ledge,
an annular protrusion,
a body below the annular protrusion,
a neck between the annular ledge and the annular protrusion, and

a base,
the annular protrusion comprising an apex, an upper slope from the apex to the neck, and a lower slope from the apex to the body,
the neck having a width that is less than a width of each port,
the process tube configured to be removably received in a port of the plurality of ports of the carrier tray, wherein, when the process tube is removably received in the port, the annular ledge of the process tube contacts a top surface of the carrier tray, the upper slope of the annular protrusion contacts the bottom edge of the port, and a difference in the width of the neck and the width of the port defines a gap between the neck and the interior wall of the port; and
a heater assembly comprising a plurality of heater wells,
each heater well comprising an inner wall and a well bottom,
the process tube configured to be removably received in a heater well of the plurality of heater wells of the heater assembly,
wherein, when the process tube is removably received in the heater well, the body of the process tube contacts the inner wall of the heater well and a gap is formed between the base of the process tube and the well bottom of the heater well, the gap configured to prevent the process tube from bottoming out in the heater well.
