SECTION 4
Maintenance of Equipment
4.1 Care and Handling
The components of the HTLE-7002 system are fabricated from acrylic, PVC, anodized aluminum
and stainless steel. 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, with de-ionized water. Wipe dry with a soft cloth or paper
towel, or allow to air dry. Whenever necessary, buffer chamber and block 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.
4.2 Maintenance
The following inspection and maintenance procedures will help maintain the safety and reliable
performance of the HTLE-7002. 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.
