Plan for the day

Equipment

  • 0.5 ml Eppendorf tubes
  • tube rack for holding Eppendorfs upright
  • pipette
  • distilled water (or growth medium)
  • low gelling temperature agarose
  • small beaker
  • heater
  • precision balance
  • microscope at 37C

Gel procedure

  • start microscope heater to 37C
  • put circuit and pipettes inside microscope box to heat to 37 C
  • heat water bath in small beaker to 60C on hot plate
  • for 0.5 ml 1 wt % agarose gel
  • 0.5 g = 500 mg water = 500 ul
  • weigh 5 mg agarose
  • put eppendorf in water bath and mix with pipette while heating

Gel into microfluidic procedure

  • Start PC and camera on microscope, choose magnification and test imaging of circuit
  • connect 2 ml syringe to output of gel channel
  • prepare connection of ul micropipette to input of channel
  • withdraw tube/syringe tip from circuit inlet
  • Fill ul pipette with agarose gel solution
  • reconnect ul pipette to gel channel input
  • On microscope with camera recording
    • inject gel
    • adjust counter pressure with outlet syringe to get lamella filled
    • when filled, aspire from inlet syringe and press with outlet syringe to get an open channel between lamellae

Execution

  • weighed 6 mg = 0.006 g + 0.6 g water = .6 ml = 600 ul water pipetted into 1.5 ml Eppendorf
  • put eppendorf in water bath on hot plate (alu paper as lid and support for eppendorf)
  • cut sharp tip off an 18 gauge syringe tip
  • blunted (320 gauge paper) the tip
  • curved the tip to get access under condenser of microscope
  • 1st try: largest
