KxS process refractometers for bioprocessing
KxS process refractometers set the standard for accuracy, hygiene and safety in the bioprocessing industries. Our refractometers seamlessly integrate through Ingold or Sanitary Tri clamp with pilot and high-volume bioreactors and ultrafiltration (UF) systems.
Typical applications:
- Fermentation to ensure consistent output quality
- Membrane filtration efficiency in protein UF separation
- Blood plasma UF quality control
- Sucrose density to capture virus rich fractions of influenza vaccines
- Enhancing evaporation and crystallization with precise steam feed optimization
Experience the high accuracy and reliability with KxS process refractometers, designed to meet the rigorous safety demands and continous manufacturing (CM) initiative in the bioprocessing industries.
Our refractometers feature industry-leading solid optics and are designed for maintenance-free operation with true stand-alone concentration monitoring. They offer a full measurement range of 0-100%, utilizing two independent 4-20mA outputs and a digital Ethernet output for versatile connectivity.
For enhanced functionality, an optional HMI unit provides a local display and interface, ensuring ease of use.
KxS Process refractometers, designed for bioprocessing and food industry applications, comply with food safety and safe food contact materials (FCMs) according to U.S. and EU regulations, including European Regulation (EC) No 1935/2004 on materials and articles intended to come into contact with food. We also comply with Commission Regulation (EC) No 2023/2006 on Good Manufacturing Practice (GMP), ensuring that our manufacturing processes are well-controlled so that specifications for FCMs remain in conformity with the legislation.
