Foxy® R1 Fraction Collector

One-rack Fraction Collectors

The Foxy® R1 fraction collector is ideal to adapt to a wide range of applications and can distribute fractions into 96-well microplates, standard tube sizes, and bottles. The single-rack design supports flexible use while maintaining a compact footprint. For essentially unlimited collection volumes, funnel racks can be used to direct fluids to any collection vessel or downstream process.

The Foxy® R1 is the basic model in the series and uses a single collection rack to maintain a compact system footprint.

Fraction collection capabilities

The system supports multiple collection modes and can reliably separate peaks by monitoring detector output, helping ensure that only relevant fractions are collected.

Fractions can be collected uniformly by:

• Time
• Drop count
• Pumped volume

Additional capabilities include:

• Storage of up to 8 collection methods
• Choice of rack configurations (specified when ordering)
• Coldroom-compatible design
• Sturdy cast aluminum frame
• Symbolic touch screen interface
• Built-in Ethernet and RS-232 communication
• Fast tube change capability
• µL delay volume between diverter valve and drop former
• Flow rates up to 25 mL/minute

Peak collection options

The Foxy® R1 allows selective collection of peaks using programmable detector-based strategies:

• Level sensing: collects peaks above a detector threshold, enabling “heartcut” collection of the concentrated peak portion
• Slope detection: collects peaks based on inflection points and can separate closely eluting peaks using valley triggers
• Time window: collects fractions only within a defined time interval
• Delay compensation: ensures peak cutting at the diverter valve regardless of tubing length

Slope-detected peaks 

You can combine accurate peak detection with uniform fraction collection modes to collect selected peaks while directing unwanted peaks and baseline effluent to waste. You can also use time windows to define collection intervals, ensuring that it collects only the desired peaks.
