What Does “Six Union” Really Mean?
- Six combined modules port:Multiple sampling, gas, nutrient and sensor connection into one aesthetically designed top-head.
- Modular head plate configuration:Six Union allows your head plate to be configured with ports specified to suit your process spargers, sampling, antifoam, sensors, feeding, harvest, etc.
- Large scale at a small size:The 100 L working volume is like a pilot-scale system but without over dominating laboratory space.
Why Choose the Six Union of The Stainless Steel Fermenter (100L)?
1. Versatile Port Configuration
With so many ports confidently available at the head as a union-style union, you can design your ferment process comfortably, with no penalties to sterilization or performance: You can device in filters, harvest lines, probes, or even forthcoming update to your fanciful, all without interruptions to sterilization or activity.
2. Proven Sterility & Clean ability
With SIP (sterilize-in-place) and CIP (clean-in-place), the system lets you maintain aseptic conditions without disassembly. ZERO dead zones, polished SS316 interior (0.4–0.6 μm), and sanitary bottom valves showcase optimized hygienic design.
3. Automation at the Helm
It has a Siemens-driven PLC and a color touchscreen (10 or 15 inches), which allows the users to indulge in a complete control of the stirring, the temperature, the pH, the DO, the gas flow and the pump dosing. Want data logs, trend graphs, or instant alarms? It’s all built-in.
4. Dual Drive Options
With 3 six-blade impellers, and either a stable agitation, 50rpm to 1000rpm mechanical, or a magnetic drive, 50rpm to 400rpm, you can select the top-drive mechanical stirring, or a bottom magnetic drive; or a combination of either one or both.

Engineered to Perform
✅ Stainless Steel Excellence
Made of high quality SS316L/SS304 that has mirror polish finish- this one is hygienic stainless steel at its best. No deader zones just clean and shiny welds.
✅ Six-Way Head Plate
Mount six sterilizable unions that are individually sterilizable which are used most commonly in sparger, antifoam, nutrient, sampling, gas outlet, probes among others. Flexible, modular, and ready for complex fermentation processes.
✅ Clean SIP/CIP Design
SIP steam-jacket sterilization can keep your system aseptic, without the arms-on trouble, as well as CIP spray ball cleaning. Automated sequences bring consistency to every run.
✅ Input-Driven Automation
Peristaltic pumps respond in real-time to the sensor input, e.g., when adding a base to correct pH, antifoam, nutrients, or adjusting the gas and the rotor meters against one another.
✅ Sensor Network
Featuring Hamilton/Mettler sensors for DO and pH, German pressure sensors, and optional additions (ORP, turbidity, biomass, CO₂), data-driven decisions, always.
✅ Powerful Control Hub
Siemens PLC ensures your fermentation is automated in more than one language, and there is logging, alarms, trend monitoring, configuration profiles and export to LIMS or Excel and it does not require additional software.

Frequently Asked Questions (FAQ)
Q: What is “six union” all about?
Each fermenter head carries six individually configurable ports (unions). Wish to retrospectively add an ORP sensor or custom sampling port? Simply swap a blank with a sensor-equipped union.
Q: Is this tank easy to clean and sterilize?
Absolutely, 0.4–0.6 µm internal polish prevents biomass sticking. Sterilization is made easier with automated SIP and CIP cycles and this ensures that each run receives an undefiled tank.
Q: What type of agitation drive is supported?
Choose between top mechanical drive (rigid torque) or magnetic bottom drive (sealed, no penetration). Both use triple six-blade impellers.
Q: How do I extract data?
The Siemens PLC supports USB, RS232, and Ethernet. Directly transfer pH, DO, temperature and setpoint trends to your LIMS or Excel.
Q: Can this ferment complex mammalian cell cultures?
Yes, including CHO, HEK293, or Vero. It is cell culture ready (2) with temperature range 5 70 C, exact DO/pH control, automatic foaming control and sterile harvest.
