Countermeasures against Biohazard
Some countermeasures are needed for a culture process of biohazard using DNA recombinant or pathogenic microbes.
The following techniques are adopted for containment and sterilization.
Features
- Exit gas sterilization by filtration
- Taking sample by closed system
- Stirring shaft seal by double mechanical seal and lubrication by sterile water
- Separated drain piping only for collecting biohazardous liquid waste
- Liquid waste sterilization system (kill tank)
*We're ready to design the total system assembly suitable for the fermentors' size and installation site.
Process automation system
All operations needed for every process are automated or semi-automated with using PLC(Programmable Logic Controller) program.
As we can supply not only our own basic package program but also customized one.
