Foxy® R2 Fraction Collectors

Foxy R2 and Foxy R2 High Flow fraction collectors uses two racks with radio frequency identification (RFID) to automatically detect collection rack​​s for easy setup.

The two-rack Foxy R2 fraction collector can be adapted to a broad spectrum of applications. The units can distribute fractions into 96 well microplates, standard tube sizes, and bottles. For essentially unlimited volumes, funnel racks can direct fluids to any collection vessel or downstream process. 

Standard Features

  • Collect peaks of interest separately using any combination of slope, level, and time window reliably separates peaks by monitoring detector output, so you don't have to expend glassware on no-interest effluent
  • Collect uniform fractions by time, drop count, or pumped volume
  • Stores up to 8 collectio​n methods
  • Choice of available racks (specify when ordering). 
  • Coldroom-friendly design 
  • Sturdy cast aluminum frame 
  • Easy to use symbolic touch screen interface 
  • Built-in Ethernet and RS-232 communication capabilities 
  • Faster tube changes 
  • µL delay volume between diverter valve and drop former 
  • Flow rates up to 125 mL/minute​

Get the Peaks You Want

Collect only the peaks you want by programming desired peak detector optio​ns.​​

Level Sens​​ing​​​
slope with horizontal line

Collect peaks above detector threshold, enabling “heartcut” collection of concentrated part of the peak.​

Slope​
slope with vertical bounds

Collect peaks based on inflection points. Separate close peaks by valley triggers.

Time​ Window
clock with time wedge

Collect only during a specific interval of time.

Del​ay Compensation
hour glass

Cut peaks at the diverter valve regardless of system tubing lengths.​​​​​​​

Slope-detected peaks

By combining Teledyne LABS' accurate peak detection with uniform fraction options, desired peaks may be collected, diverting other peaks and baseline effluent to waste. Time windows bracket desired peak fluids. Only desired peaks are collected!
