Maintenance of Equipment
10 1 Care and Handling
The plastic components of the DGGE 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 gel cassettes, spacers and combs with de-ionized
water. Wipe dry with a soft cloth or paper towel, or allow to air dry. Whenever
necessary, all components 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
undiluted alcohol's.
• 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.
10 2 Maintenance
The following inspection and maintenance procedures will help maintain the
safety and reliable performance of the Cipher DGGEK systems. Replacement
parts can be ordered by calling 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.
