The IDEX Analytical Injection Valve, Dual Mode with Switch (7725i; Cole-Parmer item 02013-14) is a manual chromatography valve for introducing liquid samples into a flowing mobile phase. It features a front-loading dual-mode design, two-position six-port configuration, included 20 µL sample loop and maximum pressure rating of 5000 psi.
Key Features
- Dual-mode sample loading, allowing partial or complete filling of the sample loop
- Convenient front-loading design, introducing samples by syringe through the needle port built into the valve shaft
- Two-position six-port configuration, providing defined load and inject operating positions
- Integrated position switch, distinguishing the 7725i configuration from the standard 7725 valve
- Included 20 µL sample loop, providing the specified sample loading volume for analytical injections
- High-pressure operation, rated to 5000 psi or 345 bar
- Durable wetted flow path, combining stainless steel, ceramic and polyimide materials
- Standard 10-32 coned ports, supporting secure chromatography fluid connections
- Compatibility with 1/16 in OD tubing, matching common analytical chromatography tubing dimensions
- Manual operator control, supporting workflows that require direct timing and control of sample injection
Benefits
- Supports controlled introduction of small liquid samples into analytical chromatography systems.
- Provides flexibility to use either partial-loop or complete-loop filling according to the analytical method.
- Simplifies initial setup through the included 20 µL sample loop.
- Handles demanding high-pressure applications up to the verified 5000 psi rating.
- Integrates readily with common 1/16 in chromatography tubing and 10-32 coned fittings.
Why Choose the IDEX Analytical Injection Valve, Dual Mode with Switch (7725i / 02013-14)?
The IDEX 7725i combines front-loaded dual-mode sample injection, a six-port valve arrangement and an included 20 µL loop in a manually controlled analytical configuration. Its 5000 psi pressure rating, integrated switch and established chromatography connection format make it suitable for demanding sample-injection workflows.
