Single-Use Centrifuges

Benefits of Single-Use Systems

Optimize Product Recovery and Scalability


Since 2009, CARR Biosystems has been providing single-use separation systems to biopharma companies seeking low-shear separation, high-recovery performance, and fast processing time. Avoid the expense and waste of CIP/SIP stainless steel centrifuges and step up to the scalable, industry-leading, UniFuge platform.

More Data in Less Time

  • Get more data in less time while lowering costs. Our smallest scale UniFuge technology - UFMicro - requires minimal cell culture volume and technician time.
  • Optimize your process performance when developing process CTQs with low-shear separation and remarkably high processing speed.

Scale-up Seamlessly with UniFuge

  • De-risk Process Scaling: Establish easily transferable CTQs as you pass clinical milestones.
  • Optimize product quality via tunable process settings (flow, force).
  • Processing volumes to support you from process development to commercial manufacturing:

Max Proc Vol25 L25 L500 L500 L2000+ L

Unsurpassed Performance

  • Optimize separation performance with best-in-class low-shear separation ensuring:
    • High cell viability for cell therapy and cellular agriculture applications
    • Isolation of antibodies from cell culture supernatant
    • Reduction of BSA levels well below the required minimum
  • Achieve high processing speeds without sacrificing the separation efficiency needed for demanding applications

With a small footprint, UniFuge systems are easy to operate, simplify training and require fewer staff than traditional centrifuges.

Title : U2k®
Heading : U2k® Single-Use Centrifugation
Listing description : The U2k is the largest member of UniFuge family, with a 9 L bowl and a flow rate up to 5-20 L/min.
Order : 3

Single-Use System

The U2k® single-use centrifuge is the scaled-up version of our successful UniFuge Pilot product. It uses gamma-irradiated, single-use modules to eliminate cleaning needs. It is designed for primary clarification of mammalian cell cultures (e.g., CHO cells) and harvesting (including washing and concentrating) stem cells and other types of cells for biotechnology and pharmaceutical applications.

  • Bowl capacity: up to 9 L
  • Flow rate up to 20L/min (5 times the flow rate of the UniFuge®.
  • Small footprint: 80 cm x 206 cm x 200 cm high (31” x 81” x 78”)
  • Easily movable with stainless steel casters leveling on skid with vibration isolators
  • Gamma-irradiated single-use modules
  • Scale processes down with the UniFuge® Pilot and UFMini®
Small Footprint

The U2k has a small footprint.

High Capacity

Process hundreds of liters of product per hour.

Confidently Scale Down

Accurately transferring operating protocols to the UniFuge® Pilot or the UFMini® is straightforward.

Streamline Processes

Uses a sterile single-use module that is easy to install and replace after each run.


Low-shear centrifugation allows for high-quality and high-recovery separation.

Save Time

Easily incorporated into a fully-automated workflow and significantly reduces processing time.


Software and automation minimize process upsets and errors.

Minimize Contamination Risks

This single-use, closed system reduces contamination risks. It provides flexibility for multi-product facilities.


The UniFuge systems are designed to resume and recover from an interrupted process without product loss.

Cell Washing

The UniFuge systems can hold materials in the bowl for washing and buffer exchanges.

How It Works

U2k modules can be tube welded to your single-use bioreactor connections (customer-specified single-use connectors available upon request). The U2k is completely automated with flexible cycle parameter entry via touch screen HMI. The feed suspension is gently pumped to the module and the cells settle to the outer radius, while the clear supernatant and concentrate are continuously discharged.
