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

Consumable supplies (pictured) and optional accessories sold separately.

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, 0.05 µm, 0.2 µm, and 0.45 µm 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 cm² nominal. Recommended for sample volumes over 200 mL and/or more complex or turbid matrices.
• Mini 25 CPTs  - The membrane surface area is 25 cm² nominal 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)
