SECTION 7

Maintenance of Equipment

7.1 Care and Handling

The plastic components of the Quadra 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 com-

ponents 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 sufcient after a thorough

wash, followed by a quick rinse in 50% ethanol.

7.2 Maintenance

The following inspection and maintenance procedures will help maintain the safety and

reliable performance of the Quadra 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), re-

place 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.
