Flexsafe STR® Bags - Microbial - AseptiQuik® Connector - Electrochemical pH, Optical DO & Probe Ports

Flexsafe® STR Microbial bags are optimized for predictable mixing and gassing performance while at the same time bringing robustness, flexibility, and speed to any stage of your microbial process.Flexsafe STR® Microbial design featuresFlexsafe STR® Microbial bags feature two 6-blade Rushton impellers ideal for microbial cultures and a ring sparger for submerse gassing. All gassing lines are equipped with either OPTA® SFT or AseptiQuik® sterile connectors for easy assembly of the included filter transfer sets. Substrate lines are made from weldable tubing for the secure connection of media, acid, base, antifoam agents and any other required feeds. Addition can be achieved either via the head space or through dip tubes. A temperature sensor sleeve, a small volume sampling line with clave connector and a bottom drain harvest line complete each Flexsafe STR® Microbial bag.Process monitoring is a complex topic and therefore Flexsafe STR® Microbial bags are available in different configurations for DO and pH monitoring. The combination of single-use optical DO and a single-use electrochemical pH sensor combines the advantages of electrochemical pH measurement with the flexibility and speed of single-use equipment. If you prefer to use conventional multi-use probes, Flexsafe STR® Microbial bags are available with sensor ports for convenient connection. The sensor ports can also be used for turbidity sensors or to perform metabolite analysis with BioPAT® Trace.Enhance safety and ease-of-useFlexsafe STR® bags are delivered gamma irradiated and ready to use. All necessary gassing line filters are included with the delivery and can easily be installed using sterile connectors. Installation into Biostat STR® bag holders is easy and straightforward. To reduce process risks, the single-use exhaust cooler in addition to the standard filter heater mitigates the risk of filter blocking. Water loss through exhaust is minimized by a separate condensate return line.Do you need more?For more specific requirements of your microbial organism of choice, reach out to your Sartorius representative to learn more on how Flexsafe STR® bags can be adapted to your process.
