10. Cleaning and Care

The Corning MicroDEN unit is compatible with 70% ethanol and 10% bleach

solution. Lightly spray the unit with 70% ethanol to disinfect before placing

in the biosafety cabinet. After use, the unit can be cleaned with 70% ethanol

or 10% bleach solution. The unit should be stored upright in a cool, dry

environment when not in use.

11. Troubleshooting

Symptom

The unit does not turn on.

Liquid does not properly

perfuse.

Liquid perfuses backwards.

Solution

Ensure the power cord is fully inserted into the

unit and wall outlet. A green light will illuminate

on the AC converter of the power cord when it is

plugged in properly.

Inspect tubing and connections to ensure

everything is connected.

Check the filters. If the filters become wetted

during use, they may not allow gas exchange,

which would cause the bottles to pressurize and

liquid to not perfuse properly.

Filters supplied with the consumables can be

replaced with a new 0.2 µm sterile filter with a

male Luer Lock.

Ensure the tubing is properly placed in the pump.

The pump has guides that keep the tubing in

place. Tubing should be placed in the center of

these guides when the pump is clamped.

Switch the tubing orientation so the tubing

coming from the left side inlet bottle enters the

left side of the pump. The colored marker on the

tubing should be to the left of each pump and

match the colored flag next to each pump head

(Figure 2).

NOTE: Placing the tubing so the colored marker is

on the right side of the pump will cause liquid to

perfuse backwards.
