Biocompatible valve technology for precision lab systems

Biotech Fluidics has developed a range of compact rotary valves designed to simplify liquid handling in life science instrumentation. Engineered with advanced polymeric sealing surfaces, these valves are fully biocompatible - making them ideal for use in analytical, diagnostic, and preparative systems where sample integrity is critical.

Replacing traditional banks of solenoid valves, a single Biotech Fluidics rotary valve can manage up to 24 channels, helping instrument manufacturers reduce both hardware complexity and costs. The design also minimises swept volume and effectively eliminates reagent carryover, supporting precise fluid control even in demanding applications.

These valves offer further advantages for laboratories working with magnetic bead separation, segmented flow techniques, or systems sensitive to pulsatile fluid motion. Their compatibility with air gaps and smooth flow profiles enhances performance in both automated and manual workflows.

Designed for versatility, Biotech Fluidics valves are available in a wide range of standard and custom configurations and can operate under pressures ranging from vacuum to 2.76 bar. Each unit is subjected to rigorous durability testing to ensure consistent, long-term performance.

Digital control options include RS232, I2C, or UART interfaces, all supported by smart closed-loop logic that allows real-time tracking of valve position - an essential feature for high-precision instruments.

For specialised applications, Biotech Fluidics offers collaborative design services. Using advanced CAD tools and computational fluid dynamics (CFD) modelling, the team develops optimised valving systems tailored to unique instrument needs - always with a focus on minimising reagent use and maximising component lifespan.

With robust internal gearing and a focus on reliability, these biocompatible valves are built to deliver maintenance-free operation across years of daily use.
