2.1.3 Compressed Air Supply
Even small amounts of water in the compressed air can lead to a corrosion of the carrier. Other
contaminations can also result in malfunctions. Use only compressed air fulfilling the following
standards.
The air must be absolutely free of water, oil, and any particles.
When air is compressed, the humidity in the air is concentrated into a smaller area, frequently
condensing inside the air hoses. Use a water separator to remove water from the air. The
provided water separator is not suitable to establish the necessary conditions; it serves only
as a control device. If you regularly observe an accumulation of water in the provided water
separator, the compressed air does not fulfill the required standards. This is extremely important!
Water in the system leads to corrosion and can destroy the device.
Use a filter with 5 μm pores or smaller to remove any particles from the air.
Set the external air pressure at least to 3.5 bars, the maximum pressure of 5 bars must
not be exceeded. The actual operating pressure should be set to 3 bars by the included pressure
regulator. The Roboocyte2 needs a minimum flow rate of 20 l/min, when the carrier is moving.
Do not use other compressed air hoses than those provided, that is, ID 4 mm OD 6 mm from
compressor to water separator, and ID 2.5 OD 4 mm from water separator to the Roboocyte2.
The use of other hoses could lead to a decrease of pressure.
2.1.4 Handling of the Carrier
Do not try to lift the carrier off the x/y table. You may move the carrier carefully sideways
by hand if necessary (for cleaning purposes, for example), but not during operation.
If it happens that any liquid spills over the x/y table, please remove it as soon as possible in order
to prevent a corrosion of the carrier.
2.1.5 Handling of the Z-Axes
Do not move the z-axes by hand. Breakage may occur. Always use the software controls
to move an axis up and down.
Change the probe with great care. Stabilize the z-axis with one hand while changing the probe
with the other.
The capillaries of the probe are sharp and may lead to injuries. Stay at a safe distance during
operation and protect your eyes. Especially take care not to move your hands in the range of
the z-axes.
Do not try to plug anything other than 0.4 mm wire or the provided connectors into the
sockets of the recording axis. Damage may occur.
2.1.6 Handling of the Ready to Use TEVC Probes
The chloride coated silver wire is sensitive to light. Always keep it dark. Make sure that all
electrodes (including the reference electrodes) are still well-chlorided before you start a recording.
They should look dark grey, not shiny. The Ag/AgCl layer deteriorates over time, leading to a DC
offset and a voltage drift over time.
We recommend that you use the provided connectors to connect the electrodes to the z-axis.
If you want to plug the silver wire directly into the sockets of the z-axis, use only 0.4 mm silver
wire for the electrodes. A wire with a greater diameter will damage the connectors of the z-axis
irreversibly.
