SECTION 5
Maintenance of Equipment
5.1 Care and Handling
The plastic components of the Large Format Cooled Vertical Electrophoresis Systems
are fabricated from acrylic and polycarbonate. Electrodes and connectors are made
from pure platinum, stainless steel, and chrome plated brass. As with any laboratory
instrument, adequate care ensures consistent and reliable performance.
After each use, rinse buffer chamber, gel tray and combs with de-ionized water. Wipe
dry with a soft cloth or paper towel, or allow to air dry. Whenever necessary, all compo-
nents may be washed gently with water and a non-abrasive detergent, and rinsed and
dried as above. Never use abrasive cleaners, glass cleaning sprays or scouring pads to
clean the components, as these will damage the unit and components.
Additional precautions:
• Do not autoclave or dry-heat sterilize the apparatus or components.
• Do not expose the apparatus or components to phenol, acetone, benzene,
halogenated hydrocarbon solvents or alcohols.
• Avoid prolonged exposure of the apparatus or components to UV light.
• Do NOT treat with diethylpyrocarbonate (DEPC)-treated water for extended
periods at 37°C. A brief rinse with DEPC-water is sufficient after a thorough
wash, followed by a quick rinse in 50% ethanol.
5.2 Maintenance
The following inspection and maintenance procedures will help maintain the safety and
reliable performance of the Large Format Cooled Vertical Systems. Replacement parts
can be ordered by calling 1-858-755-4959 or by contacting your local distributor.
• Banana plugs and power cords should be inspected regularly. If the banana
plugs become loose or do not feel friction tight replace the plugs or power
cords.
• Should power cord assemblies (connectors, wire or shrouds) show any signs
of wear or damage (e.g. cracks, nicks, abrasions, or melted insulation), replace
them immediately.
• The platinum wire is secured to the banana jack by compression between a
stainless washer and the jack nut. The nut/washer interface should be tight
and free of corrosion.
