The Deerac GX reagent dispensers and Deerac LX bulk fillers use unique magnetic feedback-controlled (MFC) technology.
 

• Fast
  High-speed valve actuation means that most plates fill in just a few seconds (e.g., 15 seconds to dispense 100 nL to 1536 wells).
• Reliable and Precise
  Wide dispense range from 0.05 µL (50 nL) to 20 µL without tip or hardware changes.
  Dependable, syringe-free system simplifies set-up and eliminates the need for helium.
  Excellent volumetric precision across a wide range of viscosities.
• No Contamination
  Non-contact. The MFC dispense mechanism eliminates risk of cross-contamination between wells.
  No system fluid. Proven air displacement pipetting eliminates contamination or dilution of sample

Real-Time Control

MFC technology is based on a dispensing tip (the valve) connected to a constant vacuum/pressure source. The tip is coupled to a real-time feedback control system. The tip contains a magnetic boss that is moved by applying a current to electronic coils situated outside the tip.
