Endy:Microfluidic Setup

This page describes the setup needed to operate a microfluidic chip via computer controlled pressure actuation. The setup described below is what we use in the Endy lab, and is adapted from the setup defined in Steve Quake's lab at Stanford.

Pressure Control

Pressure Guage (PSI Traix)

• digital pressure guage
• PG500-30-G
• I would probably find a normal, analog one instead, these have been a bit problematic -- the buttons often stick and they turn off after awhile to conserve batteries.

Microfluidics

Luer Stab Adapter (Clay Adams)

• 23 Guage
• Cost $1.5/each
• These look like needles for syringes, but have a blunt end. They are used to load the tubing with fluids. (you’ll also need standard syringes to go along with them).

Small Tubing

• Tubing, Tygon, 0.02 X .06", 100' (Cole Parmer)
• Reorder# 06418-02
• Cost $31.00 / roll (100ft)
• This tubing connects the manifold to the pins.

Large tubing

• You will need tubing to connect the pressure source to the manifolds. This will in part depend on your pressure source, but at the end you will need to reduce to tubing of size X (in order to interface with the manifold).

Pins

• Cut Tube, Type 304 (New England Small Tube Corporation)
• P/0# 67A-1064005
• 23 Guage

Computer Control / Electronics

I/O card for the BOB3 (National Instruments)

• Direct I/O to the BOB3 from the computer.
• PCI-DIO-32HS
• Jasonk 11:02, 28 July 2006 (EDT):Ty, was this specific to our computer, I forget how this played out.
• Will also need to get the cable.

Labview Controller Card (Fluidigm)

• BOB3 card, can operate 4 manifolds, so a total of 32 valves (the 6X chemostat uses 31 valves)

Automatic Manifolds (Fluidigm)

• Only one type available contains 8 valves
• $1K/each (will need 4 of them).
