Frequently Asked Questions
§3.1
With a fluidic “on/off” switch configuration, should I fill with liquid the plugged path inside the 2-SWITCH™
before screwing the plug?
If you are planning to use a 2-SWITCH™ as a fluidic on/off switch, you will need to plug either port #1 or port #2
on the 2-SWITCH™.
For example if you plug port #2, when in Position 2 the common port will be connected to the plug inside the 2-
SWITCH™. As there is still some internal volume inside the 2-SWITCH™ (12µL per position), it is better to fill the
2-SWITCH™ in Position 2 with distilled water before connecting the plug to close the position. This way, during
the experiment when the valve is actuated in Position 2 to close a path, there will be minimal liquid displacement
in the Position 2 internal volume, as it will have already been filled with liquid.
§3.3.1
How can I make a junction between a 2-SWITCH™ and tubings with external diameters different from
1/16’’?
The 2-SWITCH™ device can only be connected with
1/16’’ OD tubing and the provided fittings
, as explained in
§3.3.1. There is a wide variety of materials and internal diameters available with 1/16’’ tubing to suit your
application. However, if you have constraints on your fluidic setup that force you to use tubings of other external
diameters than 1/16’’, a wide range of
adaptors and unions
are available from the fittings suppliers, to make a
junction between your specific tubing and the 2-SWITCH™ tubing.
Warning
: Please note that
sleeves cannot be used directly in the 2-SWITCH™ fluidic ports
(risks of trapping the
smaller tubing and possible non-tight connection).
§4.3.1
How can I make a junction between an M-SWITCH™ and tubings with external diameters different from
1/16’’?
The M-SWITCH™ can only be connected with 1/16’’ OD tubing, as explained in §4.3.1. The same strategy as for
the 2-SWITCH™ can be followed if it is needed to use tubing with other external diameters on the fluidic setup
(read above).
Warning
: Please note that
sleeves cannot be used directly in the M-SWITCH™ fluidic ports
(risks of trapping the
smaller tubing and possible non-tight connection).
§8
I do not remember which device is connected to a SWITCHBOARD RJ45 port.
To identify the linked SWITCHBOARD RJ45 ports and devices, you can use the
Check connection feature
by
pushing the corresponding Check connection buttons on the SWITCHBOARD (one for each RJ45 port, see §6.2).
This will light up the green RJ45 indicators on the associated SWITCHBOARD RJ45 port and on the RJ45 port of
the device connected to it.
Other methods are applicable if using the ESS™ Control software (see the ESS™ Control User Manual).
