Standalone Vacuum Pressure-Based Controller

  • Best Seller


The LineUp™ Push-Pull is a standalone vacuum pressure-based controller with the ability to deliver finely regulated pressure or vacuum through a single outlet over the range of -800 to +1000 mbar. It can be used without a PC or controlled with Fluigent Software Solutions to benefit from control in real-time, protocol automation, graphic displays and custom integration. Combined with a FLOW UNIT, it allows for direct control of flow rate.

Features of Push-Pull vacuum pressure-based controller

Expand as needed

Combine up to 12 modules as your workflow grows. Each module is a separate and independent pressure channel.

Wide range

The Push-Pull allows for the regulation of pressure and vacuuming down to -800 mbar and up to 1 bar from one single channel.

Local control

Control without a PC using the Push-Pull hardware interface with one hand. Focus on the experiment instead of looking at the PC.

Precise volume delivery

When combined with a FLOW UNIT, one can control flow rate directly or deliver dispensed volumes as needed.

Various reservoir sizes

Support reservoir sizes from 2 mL to one liter laboratory bottles. The Push-Pull can maintain continuous, pulseless flow for days without refilling.

Description of Push-Pull Vacuum Pressure-Based Controller

Based on our industry leading experience, Fluigent has developed the patentedQuadCore pneumatic system, the most advanced microfluidic pumping technology available. Its at the heart of the Fluigent’s next generation performance, providing the fastestmost stable and compact system for microfluidics available.

In the base configuration, the system controls pressure or vacuum, and the liquid flow is a function of system resistance, fluid viscosity, etc. The addition of a FLOW UNIT enables one to control or monitor flow rate as well as measure a dispensed volume. The pressure automatically adjusts in the background to maintain the set flow rate.

When combined with the LINK module, the Push-Pull vacuum pressure-based controller capabilities are extended by using Fluigent software to control the system, or to generate time based protocols and record data (OxyGEN software).

The Push-Pull modules are available in different pressure and vacuum ranges to provide the optimum level of pressure control and resolution. These can easily be combined to match all application requirements or reconfigure the system for a new experimental design.

Discover the Push-Pull and see how microfluidics should work

With a compact and modular design, the Push-Pull allows you to set and benefit quickly from the pressure-based flow control advantages for your experiments.

“The device is well designed and allows for easy control of my microfluidic chips. What I like most is that you are independent of a computer and can directly control both positive and negative pressure.”

Christoph Trenzinger  – Stratec

Control flow rate with the benefits of responsive, pulse-free flow

With the use of pressure instead of mechanical action, the Flow EZTM microfluidic flow controller reports a responsiveness ten times faster than syringe pumps. A low response time allows users to quickly execute operations such as stop flow and pressure/flow rate steps.

Vacuum Pressure-Based Controller responsive, pulse-free flow

“The Fluigent LineUp series, including the new push-pull pump, enables precise and highly controlled aspiration and respiration of liquids. The set-up allows us to further advance our research in both continuous flow and droplet microfluidics.”

Prof. Jeroen Lammertyn, KU Leuven Belgium – Biosensors group.

Control flow rate with the benefits of responsive, pulse-free flow

Pulse-free flow is critical for generating high quality and repeatable results. The Push-Pull vacuum pressure-based controller integrates the all-new DFC (Direct Flow Control)algorithm. This allows the user to set a flow rate directly on the instrument display. The applied pressure will automatically adjust to maintain the flow rate

Focus on the microscope. No PC is required

Instead of looking at the PC, users can keep their eyes on the microscope by adjusting the control dial with one hand. In this stand-alone configuration, the vacuum pressure-based controller allows for pressure or flow rate control and volume dispense, making it ideal for benchtop use.
