circulatoren

Circulatoren are a class of compact, programmable fluid circulators used in laboratory and clinical settings to maintain continuous, closed-loop flow in bioprocessing and microfluidic systems. The term appears in Dutch literature and in English-language discussions of microfluidics as a designation for these devices.

They typically use magnetically coupled pump heads or compact motors to drive small impellers, enabling precise flow control from microliters to tens of liters per minute. Designs emphasize biocompatible materials, sterile construction, and options for incubator or clean-room use. Many models include sensors for temperature, pressure, and flow, with software that supports ramps, feedback loops, and safe shutdowns.

Applications include perfusion bioreactors for tissue engineering, organ-on-a-chip research, and continuous-flow sampling in downstream processing. The devices are valued for low shear, small footprint, and compatibility with existing laboratory infrastructure.

Adoption is growing in biotechnology, academic research, and hospital laboratories. Key considerations when selecting a Circulatoren system are flow range, fluid compatibility, sterilization method, and ease of integration with monitoring systems. Safety and maintenance requirements influence long-term performance and reliability.
