PRECAUTIONS FOR CULTURES
z
Leave space between culture containers.
Always leave space for ventilation between culture containers (Petri dishes, flasks, etc.). Inadequate
spacing may result in uneven temperature distribution and CO
2
gas concentration.
z
Do not place harmful materials in the chamber.
Never place samples that release acidic, alkali, or corrosive gas in the chamber. Doing so may cause
damage resulting from discoloration or corrosion.
z
Close the inner door and all gastight split doors.
Always close the inner door and all gastight split doors before closing the outer door. Failure to close the
inner door or any gastight split door will adversely affect performance even if the outer door is closed.
z
Open and close the doors gently.
Always open and close the doors gently. Closing the doors forcefully may cause spillage of the culture
medium, incomplete closing, or damage to the gasket. Before opening the inner door, check through the
glass to confirm that the UV lamp is OFF (if the MCO-19M(UVH)/19M(UV) or the optional MCO-19UVS is
installed).
z
Be careful when closing the outer door.
Use the handle when closing the outer door. Holding the door in other places may cause injury by getting
fingers caught in the door. Do not lean on the outer door. Doing so may result in injury from the outer door
coming loose or the Incubator falling over, or it may cause current leakage or electric shock.
z
Be careful of the inside of the outer door.
The inside of the outer door may become hot.
z
Avoid using excessive force on the inner door.
Do not put your hand on the glass, poke it with sharp objects, or apply strong force. Doing so may result
in injury from breaking the glass.
z
Check the cause of any alarm buzzer.
If an alarm buzzer sounds while the Incubator is in use, immediately check the cause of the alarm. For
details on what may cause an alarm buzzer to sound, refer to page 55.
