Moon Rock Primary Transport and Storage Container - LRL Serial # 004
The Bolt-Top Container (BTC) was the primary storage and transport
device used for lunar material. The BTC held a vacuum of pure nitrogen
gas, which is inert and does not react with the lunar material
inside.
Above: This BTC was received by me in it's original double sealed
vacuum bag. This is the first time this BTC has seen the day of light
in over 35 years. The last person to handle this artifact was a lunar
scientist in the LRL. These artifacts were sterilized after use and
vacuum sealed for future use. Rigorous procedures were used to
sterilize BTCs before being transfered into various cabinets
in the LRL. The surface of the BTC was sprayed with peracetic acid in
the R-102 (LRL atmospheric decontamination) cabinet . After 30 minutes
of soak-time, the acid was removed by sterile water spray, then dried.
This process provided biocidal sterilization without heat, as heat
would alter the lunar material.
After sterilization in the R-102 Cabinet, the BTC would arrive in the
F-201 Cabinet via a monorail to be opened, examined, and photographed.
The BTC was first inserted into a special tool called the Canholder
Assembly. The Canholder had two pegs that slid into corresponding holes
in the bottom rim of the BTC. This allowed the scientist to secure the
BTC for opening via a T-handle with socket.
Moon Rock Secondary Sample Containers
The secondary sample storage container allowed for easy division of
samples within vacuum cabinets and had high, large threads to hold
a vacuum seal in case of emergency.
You can see these containers in use in the stock NASA Apollo LRL photo below (Far Right)
Cold-Weld Container Brush
Some lunar chips and lunar soil were sealed in aluminum containers to
transfer to other labs and principal investigators. A special tool
developed by JPL would produce a cold-weld and seal the container.
Lunar dust on the containers was a problem in this cold-welding process
and as a result the stainless steel wire brush shown below was
fabricated to clean the containers prior to the cold-weld. The brush
has a large handle to compensate for stiff vacuum chamber gloves.
Moon Rock Splitting Chisel - LRL Serial # MP-1
Apollo 11 requirements mandated that all rock samples be split and
distributed to other scientific labs. These split or smaller pieces
were called daughters. Rocks were split using a mechanical
rock-splitter or a chisel like the LRL tool shown below.
Moon Rock Fines and Soil Container - LRL Serial #031
The stainless steel container shown below was used for screening
and seperating various sizes of lunar material from small chips to
dust. Different sized screening trays would fit into the top of these
containers once the lid was removed. You can see these containers in
use in the NASA Apollo LRL photo shown below (Far Right).
Lunar Fines Pouring Container - LRL Serial # 1
This
stainless steel container was used to pour lunar material into the
screening tray and other cabinet containers. It has a large handle and
lip to make tasks more efficient.

Headed by Dr. Elbert King, the LRL was constructed for quarantine,
examination, and photography of the Lunar material brought back by
the Apollo Moon Missions and was a distribution point for outbound
samples. Located in building 37 at what is now known as the
Johnson Space Center in Houston, it was also used to prepare tools and
containers used on the Lunar surface for outbound Apollo missions.

Lunar Specimen Transport Device
This
primarily stainless steel device was used by the Lunar Receiving
Laboratory (LRL) at Johnson Space Center to facilitate transportation
of sterile lunar specimens returned by Apollo crews to the Principle
Investigators (PIs) located through-out the U.S. at major institutions.
The sequence of images show a Varian gate being opened (the gate
comprises part of a sealed airlock) and the specimen cup being
exposed/extended (there are two separate knobs which regulate this).
Prior to extension the flange would have been mated to the analysis
tool (scanning electron microscope or perhaps an energy dispersive
spectrascope). The Teflon specimen cup has a ground wire which is
likely to support the SEM analysis.
