Xover® Internal Pinch-Tube Solenoid Valve

Flow selection has never been easier.

Ideal for use in cytometry, gene sequencing, in vitro diagnostics, scientific instruments, and drug discovery.

Xover – the new standard in efficient flow selection

The Lee Company is excited to introduce Xover – a groundbreaking internal pinch-tube solenoid valve designed to switch quickly and efficiently between samples, reagents, cleaning solutions or calibrants. The Xover solenoid valve features an exceptionally low carryover volume of just 3.7 μL, and a total internal volume of just 11 µL. Xover’s innovative design combines the flow path of a pinch valve with the versatile, maintenance-free performance of a chemically inert isolation valve. Xover is ideal for critical applications in flow cytometry, gene sequencing, in vitro diagnostics, urinalysis, and hematology instruments.

Key Highlights
  • Low carryover volume
  • Zero dead volume
  • Ultra-low internal volume
  • Inert materials
  • Long cycle life
