Microbial screening and media development
Start with 5 L total volume for small-volume trials, culture observation and operator training.
Applications and customer needs
Match the working volume and control package to your organism and development stage.
Batch and fed-batch process development
Select 10 L for laboratory trials involving feeding, pH correction and oxygen-demand assessment.
Scale-transition studies
Use 15 L to study a larger working volume before moving to a pilot system. Scale-up requires process-specific engineering.
Choose your fermenter size
All capacities are total vessel volume. Working ranges are planning values; final values depend on organism, mixing, aeration and foam. Contact us to configure the system for your process.
| Model | Total / working volume | Control platform | Application | |

| SJ-FS-DJ-15L | 15 L / 4.5-10.5 L | 10-inch HMI + PLC | Intermediate process development and scale-transition studies | View configuration |
Functions and customer benefits
Core functions in the proposed base package; agreed engineering and acceptance criteria govern final supply.
10-inch touchscreen + PLC
Centralizes process values, settings and operating commands. Check the process from one interface and organize routine operation.
Water-jacket temperature control
Circulates a heating/cooling medium around the culture vessel. Adjust culture temperature without a cooling coil occupying culture space.
Variable-speed agitation
Adjusts stirring within the selected drive and impeller range. Tune mixing to culture volume, viscosity and oxygen-transfer needs.
pH monitoring and dosing
Measures pH and uses acid/base pump channels under agreed control logic. Correct pH changes with less repeated manual addition.
Dissolved oxygen monitoring
Measures oxygen availability; agitation response is configured to the process. Identify oxygen limitation and guide the control strategy.
Four peristaltic pumps
Provides acid, base, nutrient feed and antifoam channels. Keeps addition duties separate and supports planned feeding.
Foam contact detection
Detects foam at a chosen height and triggers limited antifoam pulses. Respond to foam without relying only on visual checks.
Air / oxygen gas channels
Indicates flow through manually adjusted rotameters. Set the gas supply for each trial; automatic flow requires an MFC upgrade.
Exhaust condenser
Condenses part of the moisture in outgoing gas. Helps reduce evaporation and moisture carry-over; sterile filtration is separate.
Rear-access sheet-metal cabinet
Places cabinet fasteners at the rear with clean front and side panels. Provides an uncluttered operator-facing surface and an organized service layout.
Specify the right package
Make utilities, sterilization and software scope explicit before ordering.
Material and sterilization
Manual SIP engineering package proposed, requiring agreed pressure design and steam utility; automated SIP optional
Optional automation
Multi-stage recipes, MFC gas control, data export, access roles and SCADA are quoted to your requirements.
Utilities and shipping
Chiller, air compressor and sterilization utilities are separate unless quoted. Final packing dimensions and gross weight follow approved design and crating.

Frequently asked questions
Does 10 L mean 10 L of culture?
No. Capacity identifies total vessel volume. The planning working ranges are 1.5-3.5 L, 3-7 L and 4.5-10.5 L for the 5 L, 10 L and 15 L models.
How is heat removed?
Cooling water circulates through the jacket. An external chiller may be needed when available water is too warm or the culture heat load is high.
What does the exhaust condenser do?
It helps condense moisture in the exhaust and reduce evaporation and carry-over. It does not replace the sterile exhaust filter.
Does the foam probe measure foam percentage?
No. The conductive probe detects contact at a chosen height. The PLC can apply limited antifoam pulses; this is a point-detection system.
Are all stainless models automatically SIP-ready?
No. Sterilization depends on the agreed vessel, pressure design, seals, valves, steam conditions and drainage. Automated SIP is a separate option.
Can the glass vessel be steam-sterilized in place?
Do not assume this. The proposed glass route is off-line autoclaving of approved components within their permitted cycle and pressure/temperature limits.
Are chiller, compressor and sterilizer included?
Only if separately listed in the quotation. The base equipment and external utilities are itemized so the quotation matches your site.
Can you support pharmaceutical or biotech projects?
Send your URS, organism and documentation needs. Qualification support and data-integrity functions are agreed separately; no blanket GMP or electronic-record compliance is claimed.
Planning an 316L Stainless Steel Fermenters project?
Send your product type, target daily output, tray size preference, and utility limits. We will help select the model and outline the production workflow.
