Environment Control Option Operations
The ImageXpress® Environment Control option is designed to maintain an
environment for living cells to enable multi-day live-cell timelapse
imaging. Temperature, carbon dioxide, and humidity can all be
maintained within the sample plate so that cells can be kept alive for
many days, growing at a rate comparable to that expected in a standard
cell culture incubator. In addition to offering kinetic and timelapse
imaging capabilities, the environmental enclosure can accommodate a
single-channel fluidics robot for delivering compounds during
experimentation.
The ImageXpress Environment Control option can be installed together
with either the Fluidics option or the Transmitted Light option.

ImageXpress Micro High Content Imaging System Options User Guide
Environment Control Hardware
The ImageXpress Environment Control option consists of a sealing ring
on top of the sample plate and a top door above the plate that together
forms a small, sealed volume. Humidified carbon dioxide is sourced into
this small volume to form the required environment above the plate.
Temperature is controlled within the upper half of the instrument.
The ImageXpress Environment Control option consists of the following
hardware subsystems:
• Temperature control within the upper half of the base
instrument. Warm air is provided from the Environmental
Control Option Controller or the Systems Power & Options
Controller through an air hose. Feedback from temperature
sensors installed near the plate maintains the temperature. The
temperature can be controlled within a range of 30°C to 40°C,
when the ambient room temperature is 22°C or lower.
• Carbon dioxide is provided from a customer-supplied tank of
pre-mixed 5% CO2 and 95% air. The tank regulator must be set
between 15 PSI and 20 PSI. The Environmental Control Option
Controller or the Systems Power & Options Controller controls
the flow to the space above the plate, maintained by the live-cell
sealing ring. If a plate is ejected and loaded, the system conducts
a purge cycle automatically.
• Humidity is passively provided by bubbling the carbon dioxide
through a water reservoir, minimizing evaporation from the
sample plate over the duration of a timelapse experiment.
Items Included in the Installation
The following hardware components are included in an ImageXpress
Environment Control option installation:
• ImageXpress Micro Environmental Control Option Controller or
the ImageXpress Micro Systems Power & Options Controller.
See Figure 1-1 on page 11 and Figure 1-2 on page 11.
• Warm air hose and carbon dioxide tubing. See Figure 1-3 on
page 12 and Figure 1-4 on page 12.
• Temperature sensors. To ensure accurate readings, the sensors
are located near the sample plate.
• Water reservoir. See Figure 1-5 on page 13.
• Live-cell sealing ring. Compatible with 96-well and 384-well
standard height plates. The standard height for these plates is
14.35 mm ± 0.25 mm (0.5650 inches ± 0.0098 inches). See
Figure 1-6 on page 13.

After setting up the carbon dioxide
Load an unlidded plate with the live-cell sealing ring on top. If there are
concerns about contamination, a breathable seal can be used over the
top of the plate. See Loading the Sample Plate on page 18.
Note: Before you do imaging experiments, wait for the system and
plate to reach equilibrium. Allow at least two hours for the system and
30 minutes for the plate. Because focus settings and offsets change with
temperature, you might need to optimize them after the system and
plate have reached equilibrium.
5014166 D 17
ImageXpress Micro High Content Imaging System Options User Guide
Loading the Sample Plate
You must use the live-cell sealing ring to maintain the CO2 flow to the
sample plate. The sealing ring helps to contain the inputted air directly
over the cells and maintains the proper CO2 and temperature levels.
WARNING! BIOHAZARD! Wear gloves when handling sample plates.
Note: To ensure that it is at the proper temperature, before you load
the sample plate, make sure that the live cell sealing ring is in the system
or in the incubator.
To load the sample plate
1. In the MetaXpress software, click Screening > Plate acquisition
and Control > Eject Plate to open the top door of the instrument.
2. Insert the sample plate into the stage and then remove the lid
from the plate. If there are concerns about contamination, a
breathable seal can be used over the top of the plate.
18 5014166 D
Environment Control Option Operations
3. Place the live-cell sealing ring directly on top of the plate, making
sure that it fits securely onto the plate.
Figure 1-9: Environment Control option live-cell sealing ring
4. In the MetaXpress software, click Screening > Plate acquisition
and Control > Load Plate to close the top door of the instrument.
Note: Temperature fluctuations in the plate and its
surroundings cause the plate and its cells to shift in X,Y, and Z
direction. To minimize these temperature fluctuations, take the
following precautions.
5014166 D 19
ImageXpress Micro High Content Imaging System Options User Guide
Before you run an experiment:
• Allow the instrument to warm up for at least two hours.
• Make sure the plate sealing ring is at 37°C before use, either by
keeping it inside the instrument or inside an incubator. Incorrect
sealing-ring temperature can cause temperature fluctuation.
• Wait 30 minutes to 1 hour for the plate to reach equilibrium. You
can use a journal to set this waiting period.
The current temperature in the chamber is displayed on the
front of the controller.
• If there is interstitial space between wells, pipette deionized
water or media into these areas. This helps to increase the
thermal mass of the plate and reduces overall evaporation.
1.
Note: Due to the changes in Z height over time, you might need
to adjust the plate focus parameters in the MetaXpress software
occasionally. To do so, open the MetaXpress software, and then
click Screening > Plate Acquisition Setup > Plate tab > Edit Plate
Bottom Settings. Increase the adjacent well max variation to
accommodate the added Z-height variation introduced by the
fluctuation of temperature.
When setting laser autofocus options, make sure that the
instrument and plate temperatures are at equilibrium. Roomtemperature laser autofocus settings are not ideal when the
system is used at higher temperatures.
20 5014166 D
Environment Control Software
The MetaXpress software controls the ImageXpress Micro System
screening and monitors the system’s environmental parameters. You can
check Environment Control settings and connections in the MetaXpress
software.
To check the Environment Control settings
1. In the MetaXpress software, click Devices > Environment
Control.
In the simplified menu, click Control > ImageXpress >
Environment Control.
In the Environment Control dialog, the Current Temperature
and the Temperature Setpoint values are displayed.
Temperature is recorded in degrees Centigrade.
Carbon dioxide pressure is recorded as Low or OK.
Environment Control Option Operations
Figure 1-10: Environment Control dialog
When the top door of the ImageXpress instrument is opened, the
MetaXpress Software triggers the environment control to increase the
flow rate of the carbon dioxide in order to flood the chamber with
humidified and carbon dioxide-controlled air. When a plate is loaded, the
system transiently purges the carbon dioxide at a higher flow rate.
However, the MetaXpress Software does not control the parameters,
such as the level of CO
or temperature. These parameters are controlled
2
directly through their hardware devices, such as the temperature
controller on the Environmental Control Option Controller or the
Systems Power & Options Controller (Figure 1-1 on page 11 and
Figure 1-2 on page 11) and the regulator on the carbon dioxide tank.

ImageXpress Micro High Content Imaging System Options User Guide
Environmental Parameters in Image Information
The MetaXpress Software records environmental information when
images are captured as shown in Figure 1-11 on page 22.
Note: There are wire sensors in the system to detect water, but the
software does not record this as an image annotation.
Figure 1-11: Image information annotation with environmental
parameters

Doing Timelapse Experiments
The ImageXpress Environment Control option incubates live cells,
enabling imaging experiments to be performed over hours or days. Wells
can be imaged repeatedly at fixed time intervals, and movies can be
constructed from a series of images.
Note: In a timelapse experiment, the time starts when the first well is
acquired. If the acquisition time exceeds the time specified for the
timelapse experiment, the system proceeds as fast as possible. As a
result, the time between time points might not match the time
specified, but timestamps on images are accurate.
To Set Up a Timelapse Experiment
1. In the MetaXpress software, click Screening > Plate Acquisition
Setup.
2. In the Plate Acquisition Setup dialog, in the Configure tab, open
the Acquisition tab. See
Environment Control Option Operations
