General Care & Maintenance
Tank
• Disconnect leads from power supply before servicing unit.
• To remove the safety lid, push thumbs down on the plastic lugs and lift the lid vertically
with your fingers.
• Before use, clean and dry the apparatus with DISTILLED WATER ONLY.
IMPORTANT: Acrylic plastic is NOT resistant to aromatic or halogenated hydrocarbons,
ketones, esters, alcohols (over 25%) and acids (over 25%); they will cause crazing and
cracking of UV transparent plastic and should NOT be used for cleaning. DO NOT use
abrasive creams or scourers. Dry components with clean tissues prior to use.
• Before use, check the unit for any leaks at the bonded joints. Place the unit on a sheet
of dry tissue and then fill with DISTILLED WATER ONLY to the maximum fill line. Any
leakage will be seen on the tissue paper. If any leakage is seen DO NOT ATTEMPT TO
REPAIR OR USE THE APPARATUS, but notify Harvard Apparatus immediately.
• The replacement platinum electrodes are partially shrouded for protection. However,
when cleaning the main tank DO NOT use cleaning brushes in the electrode area.
Usually a thorough rinse with distilled water is all that is required.
• Ensure that the connectors are clean and dry before usage or storage.
PTFE Chambers
• Clean by rinsing with deionized (DI) water prior to each use.
• Take care to not damage the threads.
• For cases where contamination is severe, low concentration detergents may be used,
followed by rinsing thoroughly with deionized (DI) water.
Membranes
• Prior to use, rinse with deionized (DI) water and treat with your buffer solution.
• Discard membranes after use. Do not reuse.
