Luer-Activated Access 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.:  BNCHSSBH0005


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.

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
