CP Select

Experience the efficiency of the FluidPrep™ Concentrating Pipette System by InnovaPrep, engineered to simplify workflows and boost assay sensitivity. This system is highly effective in recovering microorganisms and particles, including bacteria, parasites, molds, fungal spores, whole cells, viruses, and synthetic particles, from sample volumes between 0.5 mL and 5 L.

The one-pass method uses robust filtration followed by instant sample recovery using InnovaPrep's patented Wet Foam Elution™ process delivering a highly concentrated sample ideal for detection by culture, PCR, sequencing, and more – with unprecedented speed and efficiency. For applications needing rapid, reliable sample concentration, this system provides a faster, simpler alternative to traditional culture enrichment, centrifugation, and ultracentrifugation methods.

Includes: 

  • CP Select Instrument
  • Accessory Kit  -  Includes the Storage Fluid Adapter, Permeate Line, Maintenance Tip
  • One-year manufacturer warranty

System Features

The CP Select™ when paired with your choice of filtered Pipette Tips and choice of Elution Buffer provides concentration factors beyond competing technologies, exponentially increasing detection of trace microorganisms in just minutes. Its versatility shines in its ability to process a variety of sample matrices and sample volumes. 

 

Exceptional Concentration Factors:  The combination of high recovery efficiency + large sample volume concentration maximizes concentration factors while simultaneously providing a clean buffer exchange.

  • Excellent Recovery Efficiency: High recovery efficiency is achieved using Wet Foam Elution
  • Exponential Concentration:  Variable starting sample volumes, up to 5L, can be concentrated into a single, nominal volume as low as 0.2 mL.

Fast Concentration

  • The large surface area of the filter (98cm2) enables concentration from larger sample volumes than other methods allow.
  • Customizable Run Modes:  12 customizable menu parameters for optimizing performance across different matrices.  
  • Displaces Traditional Methods: Replaces centrifugation, ultracentrifugation, and culture enrichment with a faster and more efficient process.  

Reliable Results

  • Robust System Design:  Single-use consumables eliminate risk of contamination between samples. 
  • Repeatable Results: Simple button press operation ensures consistent results between users for reliable analysis.  
  • User friendly: Standard operating protocols drive reliable consistent results.

Compatible with your Target, Matrix and Downstream Application

  • Targets: The high surface area (98 cm2)of the filtered Pipette Tips combined with the option of four pore sizes (0.45µm, 0.2 µm, 0.05 µm and an ultrafilter) enable capture of virtually any target.
  • Matrix: The  robust filtration  paired with operational menu setting options accommodates concentration from even complex matrices like clinical specimens and turbid samples.  
  • Gentle Buffer Exchange:  Variety of buffers and the gentle concentration process preserves the integrity of concentrated organisms, and are compatible with downstream applications ranging form standard analytical techniques, viability studies, or culture enrichment. 

Workflow

The Concentrating Pipette System integrates robust filtration and patented Wet Foam Elution™ process, to efficiently release particles into microliter sample volumes with maximum efficiency, delivering a highly concentrated sample ready for immediate analysis.  

Collect

Collect your liquid sample in sample container.

Prep

Capture particles onto a hollow fiber filter (Concentrating Pipette tip). Then with a button press, the particles are eluted from the filter in just seconds.

Detect

The eluted samples pair with both traditional culture or rapid molecular analysis methods, including PCR and next-generation sequencing.

FluidPrep™ CPT - Unirradiated

Single-use, Unirradiated, Concentrating Pipette Tips (CPTs) are available in a variety of formats. Selecting the ideal CPT for use with the FluidPrep Concentrating Pipette System is crucial to achieving optimal performance - both in terms of speed and concentration factor of your target. 

 

Selecting the Right CPT - Factors to consider

1 - Pore Size based on Nature and Size of Target Particle

CPTs are available in four pore sizes – Ultra, 0.05um, 0.2um and 0.45um to accommodate the wide range of target particle types and sizes. 

*Volume and flow rates will vary by matrix and selected menu settings

2 - Surface Area by Sample Matrix and Sample Volume

The complexity of your sample and overall volume to be processed will influence the speed and overall volume that can be processed effectively. Two options area available.

  • Standard CPTs Membrane surface area is 98 cm²nominal. Recommended for sample volumes over 200 mL and/or more complex or turbid matrices.
  • Mini 25 CPTs  - The membrane surface area is 25 cm²nominal and capable of smaller elution volumes with optimized menu settings. Recommended for sample volumes 200 mL or less and of low complexity/turbidity. Short-walled sample containers and the CP Sample Carousel are required for use.

As a general Rule of Thumb, we recommend using the smallest tip that provides the desired concentration factor for your application.

 

3 - Packaging Format by Target Application

All products are produced aseptically in a cleanroom environment. Understanding your downstream application will help identify which package format is best suited.

  • Non-irradiated CPTs -Bulk packaged and suitable for most applications due to the inherent low background.  Recommended if target organisms are non-ubiquitous or using selective assays.
  • Irradiated CPTs  - Individually wrapped and irradiated to provide added protection against bioburden. Best for culture-based downstream applications.

Tips are designed for use with the CP Select (sold separately) 

We recommend use with the CP sample carousel item #HC08042, and our selection of short-walled sample containers, Sample Cup Flip-Top 200ml item #HC08040-10, Sample Vial Flip-Top 10ml item # HC08041-10, and Sample Cup with Conical Bottom item #AC08106-10.
