Features:

  • Includes MultiFlow8 for precision flow splitting with equal flow rate in each channel.
  • MultiFlow8 contains 8 valves which can be switched on/offi independently.
  • Higher throughput enabling 8 assays in parallel.
  • Patented flow damper to decrease syringe pump pulses - particularly important when connecting to microfluidic biochips to prevent pusling/jerking motion comapred to standard syringe pump.
  • Flow rate: 100nL/min - 10mL/min ± 1%.
  • Standard syringes: 50µL - 5mL.
  • Dead volume: ~600µL.
  • Flow direction reversible.
  • PC controlled via VenaFluxAssay software.
  • Mirus Evo may be sold separately without MultiFlow8. MultiFlow8 can be purchased later if required.
  • Includes tubing kit for Vena8 biochips or alternative tubing kits for connection to any microfluidic biochip.

Applications: Microfluidic applications, single cell analysis, Microfluidic syringe pump for cell analysis under shear flow in biochips. Suitable for cell samples and whole blood samples.
