GP, Explosion-Proof and FMS Lab Refrigerators and Freezers
Intended Use | 3
Intended Use
The General Purpose refrigerators/freezers described in this
manual are for professional use only.
The Flammable Materials Storage and Explosion-Proof
refrigerators/freezers described in this manual are for use in
the storage of flammable inventory/samples. These models
have been listed to the appropriate standards.
These products are intended for use in research for the
storage of samples or inventory in the following temperature
ranges:
Refrigerators
33.8°F to 53.6°F (+1°C to +12°C)
Freezers
-4°F to 10.4°F (-20°C to -12°C)
These are not considered medical devices and have therefore
not been registered with a medical device regulatory body
(e.g. FDA): that is, it has not been evaluated for the storage of
samples for diagnostic use or for samples to be re-introduced
to the body.
Note:
Do not store corrosive materials in these units. Any
damage which occurs due to storage of corrosives will not be
covered under warranty claims.
Corrosive Materials Requiring Refrigerated or Frozen Storage:
•
Only use models rated as Corrosion Resistant.
•
Corrosion Resistant does not mean Corrosion Proof –
Care in storage is still required.
•
Store only corrosive reagents/samples which truly need
reduced temperature storage.
•
Flammable corrosive materials require Flammable
Materials Storage or Explosion-Proof models labeled for
the storage of corrosives
•
Containers must be wiped clean of moisture and
chemical residue before being introduced into the unit
and upon return from use.
•
Containers must be sealed with either vinyl tape or
Parafilm®.
•
Reagents/samples which release HX (X= F, Cl, Br, I) on
contact with moisture (e.g. Acyl halides, Organosilyl
halides etc.) are particularly damaging to metals.
•
Volatile amines will react with HX depositing salts which
will lead to corrosion of metal surfaces.
•
Volatile organic acids can exacerbate metal surfaces
already compromised, be sure these are securely sealed.
•
Refrigerated compartments are cool or cold areas but
they are not to dry seal your reagents and samples.
•
Bleach solutions release chlorine gas which can react
with other volatiles in the cooling chamber or directly
attacks metal surfaces.
•
Periodically clean the interiors, clean up spills or leaking
containers.
•
Failure to take precautionary actions may lead to damage
not covered by warranty claims.
