IDEX Health & Science
To be your trusted valve partner in life sciences, our designs are stringently tested in the lab to ensure they meet your system needs. The combination of advanced polymer valve-sealing surfaces ensures complete biocompatibility and longevity. Specifically designed for systems operating at pressures from vacuum to 2.76 bar, our distribution valves are verified through rigorous durability testing to ensure they deliver a robust distribution solution. A smart closed-loop control logic allows users to track the valve positioning in the system, whether controlled by RS232, I2 C, or UART.
HIGH-QUALITY DESIGN
Our valve workmanship is verified through life testing to minimize service needs and ensure a reduced total cost of ownership.
OPTIMIZED FLUID PATHS
Minimizes pressure constrictions, ensures consistent reagent usage, and eliminates reagent crossover concerns.
BIOCOMPATIBLE MATERIALS
Ensures a metal-free, ion-free pathway with full pH range compatibility.
Simplify Your Instrument Design
A single rotary distribution valve replaces a bank of up to 24 solenoid valves, affording a cost reduction as well as:
- Low swept volume
- Eliminate carryover concerns
- Enable the use of air gaps for segmented flow
- Compatible with magnetic beads
- No holding current, low current draw for delayed valve movements
- No pulsation, pumping action
- Each valve is factory-tested to specifications
- Available as standalone (for use with tubing and fittings) or manifold mountable
Selection valves offer the discrete connection of multiple fluids to a common center outport (A) or can be used to direct fluids to different flow paths in the instrument (B). All valves are customizable to your specific fluid distribution needs, whether integrated on a push or pull flow system.
Complete Valve Customization for Your Life Science System
Our design team works with you to develop an optimized valve for your system. Using state-of-the-art modeling systems and computational fluid dynamic (CFD) software, we design for minimum reagent usage and maximum lifetime. Seals are fully customized
to direct fluid as required across your platform, and passage sizes are optimized for flow needs. A wide range of materials provides the flexibility to design for cost and performance.
