15 L Jacketed Glass Fermenter Bioreactor
Jacketed Glass Fermenters
SJ-FG-DJ-15L — 15 L total volume; 4.5-10.5 L planning working range. Intermediate process development and scale-transition studies. A double-wall water jacket, 10-inch MCGS touchscreen, PLC control, pH / DO monitoring and four liquid-addition channels provide an integrated platform for microbial process development.
Why choose a glass fermenter?
Borosilicate glass makes the culture, mixing pattern and foam visible during trials. The separate water jacket transfers heat without an internal cooling coil taking up culture space. Wetted metal fittings are specified in 316L stainless steel. The proposed sterilization route is off-line autoclaving of approved components, after removal of non-autoclavable electronics and drive parts; confirm the assembled vessel fits your autoclave.
Functions and customer benefits
| Function / feature | What it does | Benefit to your workflow |
|---|---|---|
| 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. |
Optional automation and project upgrades
Multi-stage recipes can define temperature, pH, DO, agitation limits, feeding and stage-transition conditions. Automatic gas-flow / oxygen cascade requires the agreed MFC package. Data export, access roles, SCADA and qualification documentation are specified separately in the quotation. These options are not included automatically.
Applications in biotechnology and pharmaceutical research
Designed for laboratory microbial fermentation: bacterial and yeast culture, media optimization, enzyme production research, probiotic process development, recombinant microbial expression and training. Batch and fed-batch workflows are configured to the organism, feeding strategy and oxygen demand.
For pharmaceutical process development, send the URS and required documentation scope. Mammalian cell culture, high-viscosity broths and unusual solvents require a separate engineering review; a standard microbial package is not automatically suitable for every process.

*Planning working ranges depend on mixing, aeration, foam and the organism. Model capacity refers to total vessel volume.
Made to order in Zhejiang, China. Request a quotation matched to your selected configuration, utilities and documentation needs. External utilities and optional upgrades are supplied only when specified. Planning lead time: 60 calendar days after technical and commercial approval; confirm before ordering. Proposed warranty: 12 months for manufacturing defects, subject to quotation terms.
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.
