• Make certain that the pinch clamps on the two waste bags are CLOSED.
• Remove the threaded fittings from the middle ports of the waste bags.
• Remove the waste bag assemblies (waste bag enclosed in netting) from the hooks on the underside of
the center plate of the carousel.
• Set the waste bag assemblies aside for proper disposal of the waste.
CAUTION: The waste solution will contain potentially hazardous organic compounds, hydrochloric
acid, and, most importantly, cadmium ions (Cd
2+
) which are toxic and a potential human
carcinogen. Users should be aware of two important warnings when dealing with this waste
solution:
• Be certain to wear appropriate personal protective equipment including disposable
gloves and proper protective eyewear when handling the waste bags and the waste
solution.
• Be certain to dispose of the waste properly. Unless specifically allowed by your local
wastewater authority, the waste should NOT be emptied into a sanitary sewer, i.e. a sink
drain. Instead, the waste should be collected in a suitable container and disposed of
with an approved waste handler. This waste handler should be contacted BEFORE you
accumulate waste in laboratory or field studies so that the proper storage vessels are
available and a schedule for waste pick-up has been arranged.
• To empty each bag into the appropriate container, invert the bag so that the port is in the “down”
position and is over the waste container. Then carefully open the pinch clamp and allow the waste
solution to flow out of the bag. Use gentle pressure on the bag to facilitate the process and make sure
that all of the solution has been removed. Note, however, that it is not important to rinse the waste
bag before reinstallation.
2.8.2 ATTACHING THE WASTE BAGS
To install the waste bags prior to deployments, place the carousel on the floor or bench in a vertical
position supported by its three legs, as shown in the pictures above, and follow the step-by-step instructions
below.
• Open the pinch clamp on the port of the waste bag and place the bag assembly on a flat surface.
• Place your hand on the closed end of the bag and move it across the bag toward the end with the
fitting, squeezing out any air through the pinch clamp fitting.
• Close the pinch clamp.
• Locate one of the tan-colored threaded fittings on the waste lines and attach it to the pinch clamp port
of the waste bag. Tighten securely with fingers only – no tools should be used.
• Hang the empty waste bag assembly (waste bag in netting) on two of the hooks on the underside of the
center plate of the carousel.
• Install the second waste bag repeating the steps above.
