Triple point of water cell shipping enhancements

A triple point of water cell designed for reduced breakage during shipping comprising:

• a) a cell body used for realization of the triple point of water for thermometer calibration having a cell body volume,
• b) an upper annular chamber having a storage volume and a central opening,
• c) said central opening substantially coaxially aligned to said cell body,
• d) a transfer tube connected between said cell body volume and said storage volume,
• e) purified water residing within a connected volume of said cell body volume, said transfer tube, and said storage volume, and
• f) said purified water is substantially positioned in said storage volume prior to shipping.

A triple point of water cell designed for reduced breakage during shipping comprising:

• a) an elongated triple point of water cell body having an elongated cell body volume, said elongated cell body volume having a first volume per unit length,
• b) a storage volume having a central opening, said storage volume having a second volume per unit length,
• c) said second volume per unit length is greater than said first volume per unit length,
• d) a transfer tube that connects said elongated cell body volume and said storage volume,
• e) said transfer tube having an arc shape within said storage volume,
• f) purified water residing within a connected volume of said elongated cell body volume, said transfer tube, and said storage volume, and
• g) whereby purified water is substantially sequestered in said storage volume regardless of orientation during shipping.
