Instruments - Microarray Processing - FlowTest™ Programmable Microfluidic Controller

Arrayit FlowTest™ Microfluidic Controllers are fully automated and programmable controllers that operate up to eight fluidic or microfluidic control components.  FlowTest™ is adaptable for use with pumps and valves that are actuated with 12 or 24 volts including Lee, Takasago, Burkert, Bio-Chem Fluidics and other solenoid valve and pump manufacturers. These components can be run in parallel or independent of one another. Programming is carried out on a computer, using the dedicated CosDesigner™ software. This programming tool is ideal for the development of new procedures that require liquid displacement, sampling, and injection. Multiple programs can be set up, stored and managed and users can effortlessly retrieve and run their programs. FlowTest™ field of use spans laboratory and industrial applications requiring precise liquid transfers and will prove an invaluable asset in many quality testing applications.

FlowTest™ can also operate as a stand-alone instrument without a computer.  In this case, programs are loaded with the help of a USB key, and the controller is then operated by a “run” and a “stop” button conveniently located on top of the control box.

Bring your ideas to life. Our FlowTest™ controller quickly permits you to design and run your experiments. By controlling up to eight valves and pumps (12 or 24 Volt), a wide variety of fluidic and microfluidic operations can be performed.

Simple and user friendly. The graphic user interface of the CosDesigner™ software is straightforward and intuitive. The biologist, chemist, laboratory technician, quality control technician or other user can efficiently program the controller without having to learn complicated programming languages.  Programming is accomplished in two easy steps:

  • Design your fluidic flow diagram in a graphic window using a library of valve and pump components.
  • Set the parameters (open and closing times, amount of fluid, interrupts) and launch the program.

Efficient and reliable. Improve your productivity with the FlowTest™ controller.  CosDesigner™ allows the user to monitor several precisely timed fluidic flow operations simultaneously. Wide programming parameters allow the controller to run complex sequences for extended periods of time.
