The IDEX Stainless Steel Sample Loop, 10 µL, 7125/7010 (IDEX 7021, Cole-Parmer item 02016-34) is a 316 stainless steel sample loop designed for IDEX 7125 and 7010 injection valves. It provides a nominal 10 µL sample volume with 1/16" OD x 0.012" ID tubing and a 20° port angle for connection to the compatible valve ports.
Key Features
- Designed for 7125 and 7010 injection valves, with geometry configured to match the compatible valve ports
- Nominal 10 µL sample volume, providing a defined loop volume for sample injection
- 316 stainless steel construction, providing high pressure resistance and low permeability
- 1/16" OD x 0.012" ID tubing, with a verified inside diameter of 0.30 mm
- 20° port angle, configured for the specified 7125 and 7010 valve models
- Square-cut, burr-free tube ends, supporting a firm and flush connection to the valve ports
- Supplied with unswaged fittings, allowing the tubing to be fully bottomed in the injection port before the ferrule is swaged
- Includes two fittings with ferrules, providing the connection components required with the sample loop
Benefits
- Supports accurate and repeatable sample handling with a defined nominal 10 µL loop volume.
- Allows proper seating in compatible injection valve ports through square-cut tubing ends and the specified port geometry.
- Simplifies initial fitting installation because the supplied fittings are unswaged before connection.
- Provides durable fluid handling performance through stainless steel construction with low permeability.
- Supports continued use of compatible 7125 and 7010 injection valves without replacing the complete valve assembly.
