Single-Use, Irradiated 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 are 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.

Fine upstream clarification for difficult, high-particulate liquid samples

The FluidPrep™ 1 µm Upstream Clarification Filter is a single-use fine prefiltration tool for reducing persistent suspended particulates before concentration. Use it when cloudy, clay-like, wastewater-impacted, environmental, or other difficult liquid samples contain fine solids that may interfere with CP Select™ or EasyElute™ workflows.

Because 1 µm filtration may retain cells, protozoa, fungi, organism fragments, biofilm-associated material, particle-associated eDNA/eRNA, or solids-associated targets, users should evaluate target recovery before routine use.

Some complex liquid samples contain fine suspended particles that remain after settling or coarse screening. These particles can contribute to slow flow, premature filter loading, or inconsistent concentration performance.

The FluidPrep™ 1 µm Upstream Clarification Filter supports the Clarify step of the InnovaPrep® 4C Workflow — Characterize → Condition → Clarify → Concentrate — by reducing fine particulate burden before concentration when a less aggressive approach is not sufficient.

Best used when samples contain:

• Persistent fine suspended solids
• Cloudy or clay-like turbidity
• Fine mineral or sediment load
• Wastewater-impacted water with difficult fine particulates
• Environmental water, stormwater, canal water, lagoon water, or receiving water with persistent haze
• Large-volume samples that remain difficult after coarse debris removal
• Samples where direct CP Select™ or EasyElute™ concentration is limited by fine particulate burden

For gross debris, use coarse screening (e.g. 100 µm Mesh Upstream Clarification Filter). For CP Select™ workflows where fouling occurs during concentration, consider CPT-Attached Matrix Prefilters.

The BeFlat™ Degassing Jar is a patented, reusable sample-preparation tool designed to reduce dissolved gas in beer, soda, hard seltzer, cider, sparkling beverages, and other gasified liquids before concentration or downstream analysis.

Carbonated beverages can release CO₂ during sample handling, creating bubbles and foam that may slow or disrupt concentration. BeFlat™ helps prepare these samples for more reliable and efficient CP Select™ processing, supporting faster microbiology workflows that concentrate bacteria and other spoilage organisms from large sample volumes before culture-based or molecular testing.

When paired with CP Select™ Concentration Tips and Wet Foam Elution™, BeFlat™ enables a streamlined carbonated beverage workflow:

           Degas → Concentrate → Elute → Test

Benefits

Prepares carbonated beverages for CP Select™ concentration

Helps reduce bubbles, foam, and CO₂-related flow disruption

Supports beer-spoilage organism and beverage QC workflows

Useful before 0.45 µm or 0.2 µm CPT workflows

Reusable, autoclavable borosilicate glass jar

Supports culture-based or molecular downstream testing workflows

Streamlined Workflow

1 - Degas with BeFlat™
- Pour the carbonated beverage into the BeFlat™ Degassing Jar to release CO₂

2 - Concentrate with CP Select™

Coarse upstream debris management for FluidPrep™ concentration workflows

The FluidPrep™ 100 µm Mesh Upstream Clarification Filter is a simple, single-use prefiltration tool for reducing gross debris before concentration. It helps make large-volume, debris-containing, or wastewater-impacted liquid samples more processable before CP Select™ or EasyElute™ workflows.

Use it when fibers, vegetation, grit, algae, large particulates, produce debris, or other coarse material may interfere with downstream concentration.

Main product description

Complex liquid samples often contain large debris that can slow processing, clog downstream components, or make concentration less reliable. The FluidPrep™ 100 µm Mesh Upstream Clarification Filter provides a practical first clarification step before FluidPrep™ concentration workflows.

As part of the InnovaPrep® 4C Workflow

 Characterize → Condition → Clarify → Concentrate

The 100 µm Mesh Upstream Clarification Filter supports the Clarify step by removing coarse debris only when needed.

The goal is not maximum solids removal. The goal is target-aware matrix management: reduce gross debris and improve processability while preserving the biological fraction needed for downstream analysis.

Best used for

• Wastewater and wastewater-impacted waters with visible debris
• Environmental water, stormwater, canal water, and surface water samples
• Produce rinse or wash water with pulp, fibers, soil, or plant material
• Aquaculture, pond, lagoon, or recirculating water samples
• Large-volume water samples containing grit, algae, vegetation, or sediment
• Workflows where coarse debris should be removed before CP Select™ or EasyElute™ concentration

Common applications
