ULC Series
Ultra low carryover valve
The Ultra Low Carryover Valve features both unrivaled low carryover and the ability to reduce fluidic circuit complexity by replacing multiple valves with a single valve. The valve uses a patent pending approach to increase throughput and decrease liquid waste by reducing wash times. Additionally, the Ultra Low Carryover Valve offers superior performance as a gradient proportioning valve for HPLC, HbA1c and other life science applications.
Features
- Best in class low carryover performance
- 3 port valve offers four modes of operation: flow off, flow channel A, flow channel B, flow channel A + B.
- Simplifies OEM instrument design by using fewer valves
- Internal volume as low as 4.13 μL from common port to orifice seat
- CE, IP-65 Rating, REACH and RoHS compliant
