CARR Biosystems About Us


The CARR Biosystems Story

CARR Separations was founded in 1993 by Robert “Bret” Carr and his father Bob Carr in Medfield, MA. Together, they introduced the Powerfuge Separation System, the first high-speed, solid bowl centrifuge with automatic solids discharge. Through the 1990's, CARR Separation established itself as an industry innovator and a world-class supplier of liquid-solid separation to the Life Sciences and Specialty Chemical markets.
In 2000, CARR Separations was acquired by Kendro Laboratories Products LLC. The Powerfuge and Viafuge Separation Systems were combined with Centritech Separation Systems to form the Kendro Bioprocess division.
In 2004, Barry-Wehmiller (Pneumatic Scale Angelus) acquired CARR Centritech Separation Systems, relocating all functions to Clearwater, Florida. In 2009, the company introduced the UniFuge® Single-Use Separation System.


In 2022, CARR Centritech became CARR Biosystems. Today, CARR Biosystems draws on our decades of expertise with a renewed focus on high-quality centrifugal separation systems. Our high-quality products are designed to meet the most stringent safety and quality standards across multiple applications.
