Care and Maintenance
Cleaning
• Do not autoclave or heat any part above 45 °C.
• Do not expose the unit or its parts to organic solvents.
• If using radioactive reagents, decontaminate the unit with a cleaning agent such as
CONTRAD 70 or Decon 90 from Decon Laboratories, Inc.
Rinse the DALT Tank, cassettes and sponges with distilled water immediately after each
use. Allow the unit to air dry completely. Periodically wash with a dilute solution of a
mild detergent.
Clean gaskets with mild detergent and rinse with distilled water. Allow to air dry.
Clean glass plates and spacers with a dilute solution of a laboratory cleanser such as
RBS-35, from Pierce Chemical Company. Rinse thoroughly with tap and distilled water.
Glass plates can also be treated with (but not stored in) acid cleaning solutions.
Removing the Electrode Panels from the DALT Tank
You can remove each electrode panel for more thorough cleaning, or to replace
damaged electrodes.
1. Use a Phillip’s head screwdriver to loosen the white plastic retaining screws on the
exterior of the DALT Tank. You do not need to remove the screws.
2. Lift and slide the panel out.
