Hints for Handling CA
NEVER use the system without first protecting the inside surfaces of the
clear chamber with Rain-X® or Rain Block
TM glass water repellent.
Labconco has tested these two treatments, and found they protect the clear
chamber from CA fumes for up to 20 uses, if the treatment is not disturbed.
Always follow the treatment manufacturer’s instructions when applying the
treatment. Labconco has not tested any other brands of glass treatment
chemicals, and cannot recommend their usage.
CA will react and polymerize on any surface or material that is wet or damp.
NEVER use the system on wet or damp evidence.
If the relative humidity of the operating environment is less than 30%, and
you wish to increase the humidity in the clear chamber before developing
fingerprints, place NO MORE THAN 1-2 drops of water in a heating pan,
and place it on the heater. Using more than 1-2 drops of water will result in
saturation of the air and condensation inside the clear chamber. The CA
fumes will react with condensation, reducing the clarity of the chamber.
NEVER use the system when there is condensation on the inside of the clear
chamber or on evidence.
If you are trying to reuse CA heating pans, discard them after the second use.
If reused more than a single time, buildup of residue on the bottom of the pan
will affect the transfer of heat to the glue.
Don’t use any heating pan with a dented or warped bottom; it will not heat
the CA as efficiently.
Because the presence of moisture causes the glue to set, exposure to moisture
in the air can cause a tube or bottle of glue to become unusable over time. To
prevent an opened container of glue from setting during long term storage,
store it in a freezer, or in an airtight jar or bottle with a package of silica gel.
