ANY QUESTIONS?

To learn how to connect the 2-Switch™ on the Switchboard, go to the ESS™ section.

Concerning the tubing connection:

  • Cut the 1/16’’ OD tubing to the desired length, leaving a square-cut face.
  • Slide the nut over the tubing with the nut thread facing the tubing end being connected.
  • Slip the ferrule over the tubing, with the tapered portion of the ferrule facing the nut.
  • Insert the assembly into the receiving port, and while holding the tubing firmly against the bottom of the port, tighten the nut finger tight.
  • To check the tightness of your connection, you may pull gently on the tubing: it must stay fitted in the ferrule and nut.

Warning:

  • The 2-SWITCH™ device can only be connected with 1/16’’ OD tubing.

You can clean the 2-Switch™ in the same way than the Flow Unit.

Besides, Fluigent strongly advises you to use filtered solutions. Wetted material is Teflon® only.

The 2-SWITCH™ can only be connected with 1/16’’ OD tubing and the provided fittings. 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 set-up that force you to use tubing 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).

Back to FAQs

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 no air bubble and a minimal liquid displacement in the Position 2, as it will have already been filled with liquid.

HIGH-THROUGHPUT CELL DNA SCREENING USING DIGITAL PCR

The use of water-in-oil droplets in microfluidics in high-throughput screening is rapidly gaining acceptance. The main application areas currently involve screening cells as well as genetic material for various mutations or activity. Here the aim is to isolate single DNA molecules and analyze the enzymes and proteins resulting from their expression.

FLUID RECIRCULATION FOR CELL PERFUSION WITH REDUCED SHEAR STRESS

Many microfluidic applications require expensive solutions to be injected at a controlled flow-rate into a microfluidic system, such as cell cultures, PCR processes, cell injections or simulation of blood capillaries with a controlled minimal mechanical stress.

IMPEDANCE SPECTROSCOPY ON CHIP FOR CHARACTERIZATION AND COUNTING OF CELLS AND PARTICLES

Information, such as cell size, type discrimination and other quantitative characteristic information can be measured for biological systems using impedance spectroscopy. Our electrical impedance spectroscopy platform (or EISP) offers the advantage of acquiring this information from cells, or particles such as beads, without the need to label them, as would be needed for characterization using […]
