Luer-Activated Access Valve with one-way Check Valve on C-Flex Tubing

Safely and securely collect more than hundred samples into syringes through the luer-activated access valve.

Validated to maintain a microbial battier after 140 connections, the system is ideal for high-frequency sampling for process monitoring including pH, gas concentrations, metabolites, nutrients, IgG and more.

Item no.:  BNCHSSBH0004


High Capacity Sampling

The luer-activated access valve on BENCHMARK™ is validated to maintain a microbial barrier after 140 connections with a male-luer device including syringes for sample collection.

Easy to Use

Simply swab the surface of the fitting with a sanitizing agent, connect a sterile syringe and collect your sample.

Clear residual liquid in tubing into a purge syringe before taking the next sample. Protein flushing studies demonstrate 100% clearance from access site after total flushing of 3mL.

Gamma-Irradiated and Ready-to-Use, simply weld-on to tubing from your process vessel.

Added Security

BENCHMARK™ includes a one-way check valve immediatly downstream from the connection site. The valve prevents fluid or air from flowing into your vessel helping to preserve purity in your process vessel.

Sample Smarter

BENCHMARK™ preserves sterility on the vessel the sample is collected from. The sample is open to the environment once the collection container is disconnected from BENCHMARK™ and so not suitable for bioburden|sterility testing, endotoxin testing or retain samples.

Critical Properties

Aside from validation to maintian microbial barrier properites after 140 engagments, BENCHMARK™ meets the following standards:

  • USP Class VI
  • USP 85
  • USP <381>
  • USP <661>
  • 21CFR177.2600
