carefully selected to meet the power requirements of the NIFS in all
configurations and to comply with all safety standards.
Aria is a perfusion system which automates perfusion or timed
injection protocols. It allows for the sequential delivery of up to
10 different solutions at the desired flow rate into a microfluidic
chip, perfusion chamber or petri dish.
Do not open or dismantle the NIFS device.
Please refer all servicing to after-sales service
department (support@fluigent.com)
Prevent any objects or liquid from entering the NIFS device, this may
cause a short-circuit failure or other malfunction. Failing to respect
this advice would:
• Expose you to direct current/voltage in case the device is under
voltage which may lead to severe damages
• Void device's warranty
• Discharge our company from any liability regarding physical or
device damages.

The NIFS is dedicated to flow rate measurement and control when
combined with Fluigent pressure controllers. It allows for pressure-
based flow rate control without contact with the liquid.
For applications that require a contamination-free environment,
several types of fluids, continuous operation with slow flow response
time, and flow rates ranging from 100 µL/min to 10 mL/min, we
recommend the NIFS.
INTRODUCING NIFS
This manual will show you how to assemble the NIFS. It will describe
the product’s functionalities and will teach you how to connect and
use it with its required components.

6
GENERAL INFORMATION
The NIFS allows flow rate measurement over the range of 100 µL/min
to 10 mL/min. The liquid flow rate delivered is computed from the
measurement of the gas flow rate sent to the reservoir.

When purchasing a NIFS [1], you receive one ready-to-use flow sensor
with one electric cable [2] (USB-C to USB-A) and an adaptor [3] (USB-A
to micro-USB) to connect it to the software. The sensor consists of
sensing elements and electronics integrated into a compact case.
Standard M3-sized screws can be used for fixing the device.

Reservoirs of three volumes are available with the NIFS: 2 mL, 15 mL
and 50 mL. In order to function properly, the NIFS requires 15 mL and
50 mL reservoirs with a P-CAP screw (a P-CAP lock is not compatible
with the use of the NIFS for these volumes).
The NIFS has two (2) pneumatic ports that are compatible with 4 mm
OD (outer diameter) tubing. To get started, FLUIGENT can provide
different kits that include tubing, and a male luer integral lock ring.
1Cut the OD 4mm tubing to the desired length, leaving a square-cut
face.
2Insert the tubing into the receiving port and press as far as it will go.
3To check the tightness of the connection, pull gently on the tubing: it
should slightly move but stay fitted in the rubbing part of the port.
4Do the same thing on the 2nd port.
5To disconnect the NIFS, push on the rubber part while pulling the
tubing out of the port for each side.

If using the Fluigent F-OEM [1], users can directly connect the NIFS
[2] to the pressure module using the micro-USB connector [3]. They
can also connect the NIFS to the integration board or the computer
using the USB-A connector. It will be automatically detected (the LED
near the USB-C socket becomes green).

The NIFS is fully supported by Fluigent SDK. It has been ported to the
most popular programming language within the instrumentation
field (LabVIEW, C++, C# .NET, Python, and MATLAB).
This SDK merges all Fluigent pressure controllers and sensor
instruments and provides an advanced regulation loop. Specific
functions have been implemented for the NIFS:
fgt_get_sensorValue
fgt_get_sensorBypassValve and fgt_set_sensorBypassValve
To read all functions and the user manual, visit the following webpage:
https://github.com/Fluigent/fgt-SDK
Fluigent OxyGEN software supports the NIFS with version 2.2.0 or
higher. The sensors will be identified and the same level of features of
our end-user products are available.

1First, insert the NIFS between the pressure controller and the
reservoir with the correct tubing.
2Connect the NIFS to the computer for use with the PX, the P-OEM or
the F-OEM, or directly connect it to the F-OEM.
3The NIFS is now ready for your application.
Here is a quick setup guide to get your NIFS up and running.

The NIFS can be used in a large range of temperature, but some
elements need to be taken into account:
- The tubing between the pressure controller and the NIFS and the tubing between
the NIFS and the reservoir should be < 1 m to optimize response time.
- Do not touch the NIFS when operating for measurement stability.
- Performance is not guaranteed for temperatures below 15°C or beyond 37°C.
- The temperature should remain constant during operation.
- It’s recommended to use an air filter to protect the sensor.
- Calibration is required for gases other than clean air.
- The regulation performance is not guaranteed for liquids which flow rate is not
linear with the pressure applied (ex: alginate) but measurement is not affected.

When air flows in the NIFS, it can go through two paths. One has a
sensor that measures the air flow rate and the other has a bypass
valve. If pressure is applied, the sensor reduces the passage of air,
which increases the response time.
When the NIFS is used for regulation or when a manual pressure
command is made, the algorithm automatically optimizes the
response time/stability ratio by controlling the opening/closing of the
valve to facilitate the passage of air.
Please note that when the valve is opened, the LED near the USB-C
socket becomes blue (when the valve is closed, the LED is green) and
the flow rate monitoring is stopped as no air goes through the sensor.
Manual control of the opening of the valve is possible via the dedicated
function of the SDK or the dedicated button on OxyGEN.
FAQ
Is it possible to use the NIFS with other manufacturer’s pressure
controllers?
Flow rate monitoring is possible, but performance is not guaranteed.
