Adjustable Slab Gel Manual 07/13
SECTION 5
Maintenance of Equipment
5.1
Care and Handling
The plastic components of the Adjustable Slab Gel units are fabricated from acrylic, delrin 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, glass plate, 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 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.
5.2
Maintenance
The following inspection and maintenance procedures will help maintain the safety and reliable
performance of the Adjustable Slab Gel 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.
