Troubleshooting for Cellbags

The Cellbag appears to be overinflated

Possible cause	Suggested remedy
Too high airflow	Check that the airflow to the bioreactor does not exceed 0.5 Lpm. (The Cellbag should be inflated so that it requires force to squeeze it. However, it should not be so pressurized that creases form near the attachment points.)
Faulty relief valve	Check that air is passing out of the pressure relief valve: attach a short length of tubing to the exhaust vent and immerse the tubing in water to a 1 cm depth. Bubbles should appear indicating flow. If no flow is observed, remove the pressure relief valve. The outlet filter may be plugged and removing the pressure relief valve may allow continued operation. (The Cellbag should be inflated so that it requires force to squeeze it. However, it should not be so pressurized that creases form near the attachment points.)
Faulty Cellbag	If the Cellbag continues to overinflate, transfer the contents to another Cellbag. (The Cellbag should be inflated so that it requires force to squeeze it. However, it should not be so pressurized that creases form near the attachment points.)

Possible cause

Check that air is passing out of the pressure relief valve: attach a short length of tubing to the exhaust vent and immerse the tubing in water to a 1 cm depth. Bubbles should appear indicating flow.

Faulty Cellbag

If the Cellbag continues to overinflate, transfer the contents to another Cellbag.

(The Cellbag should be inflated so that it requires force to squeeze it. However, it should not be so pressurized that creases form near the attachment points.)

Collapse

The Cellbag appears to be underinflated. (An underinflated Cellbag will generate excessive foam and poor mixing.)

Possible cause	Suggested remedy
Too low airflow	Check that there is sufficient air flow to the inlet filter. (An underinflated Cellbag will generate excessive foam and poor mixing.)
Inlet air supply wrongly connected	Check that you have connected the inlet air supply line to the inlet filter.
Missing pressure relief valve	Check that the pressure relief valve is present on the exhaust filter.
Obstructed flow paths	Check that air inlet and out flow paths are unobstructed.
Clogged exhaust filter	If the exhaust filter is clogged then transfer the contents to another Cellbag.

Collapse

Excessive foaming in the Cellbag. Some amount of foam is typical. Foam should not cover more than 50% of the surface area.

Possible cause	Suggested remedy
Poorly inflated Cellbag	Check that the Cellbag is rigidly inflated. A poorly inflated bag will foam rapidly.
Too high rocking rate	If foam is still excessive after a few hours of operation, reduce the rocking rate. Make sure that the new rocking rate provides a sufficient dissolved oxygen concentration.
Too big rock angle	Reduce the rock angle. The bioreactor base units are factory set to ±6° from the horizontal. This angle has been found optimal for most cell lines.
