5 L 316L Stainless Steel Fermenter Bioreactor

SJ-FS-DJ-5L — 5 L total volume; 1.5-3.5 L planning working range. Small-volume microbial screening, media development and training. 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 316L stainless steel fermenter?

A 316L product-contact vessel provides a metal construction for repeated laboratory development campaigns. The separate thermal jacket supports heating and cooling around the culture. Surface finish, cleaning access, seals and drainability are specified for the application. The proposed manual SIP package requires an agreed vessel pressure design, steam utility, valves and drainage; automated SIP is an option.

Functions and customer benefits

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.

Configuration and technical parameters

Measurement ranges are not control-accuracy guarantees. Performance, utility requirements and acceptance tests follow the approved technical specification and FAT checklist. Images are concept illustrations, not photographs of a measured production unit.

*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.

Information to include in your enquiry

Tell us the organism, total and working volume, batch or fed-batch process, broth viscosity, target temperature, aeration / oxygen demand, sterilization route, utilities, electrical supply, recipe and data requirements, delivery address and documentation scope. This lets us match the vessel, drive, probes, gas train and software to your process.
