CP Select™ Concentrating Pipette

Adjustable sample stand for use with CP Select™. 

For use with CP Select™ only

Optimize the performance of your FluidPrep™ Concentrating Pipette System with our specially formulated Elution Buffers. Designed to enhance concentration efficiency through our patented Wet Foam Elution™ process, choosing the right elution buffer ensures optimal recovery, target integrity, and seamless compatibility with downstream applications. Use our guide to select the best elution buffer for your specific needs.

Note:

PBS, PBS-X and Tris Elution Fluids are irradiated and have min. of 90 days shelf-life at time of shipment. 

DMEM Elution Fluid is available in a 5-pack only, is non-irradiated. Store refrigerated.

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)
