Product Overview
Water-Jacketed Glass Bioreactor Vessel for Bench-Scale Fermentation – Used
Product Condition
Used. Visual inspection only. Borosilicate glass vessel appears clear with no visible cracks or chips and shows cosmetic wear consistent with laboratory use. Two rubber top port fittings show cracking and material degradation and will require replacement (shown in the photos). One included bottle contains dried internal residue. No functional testing has been performed.
Carefully packed and shipped same business day from our Idaho warehouse. Online since 1999. Honest equipment and straightforward service.
Product Overview
Sartorius-type jacketed glass bioreactor vessel intended for bench-scale laboratory fermentation and culture work. The system consists of a clear borosilicate glass vessel mounted in a stainless steel support frame with integrated handles and a flat stainless steel multi-port headplate. A double-wall water jacket surrounds the vessel for connection to an external circulating heater or chiller, allowing controlled thermal exchange during operation. The overall mechanical layout and component geometry align with European bioreactor designs commonly used in the 1990s to early 2000s, where modularity and serviceability were prioritized over integrated automation.
Key Features
- Graduated glass vessel marked from 1 L to 4 L working volume
- Additional headspace above 4 L marking; total capacity exceeds labeled volume
- Borosilicate glass construction for chemical and thermal resistance
- External double-wall water jacket with top and bottom circulation ports
- Stainless steel support frame with integrated carrying handles
- Flat stainless steel headplate with multiple threaded ports
- Top-entry geared agitation coupling; no motor or controller included
- Stainless steel internal agitator shaft with fixed-position impellers
- Removable top port fittings; two rubber fittings present but degraded
Applications
- Bench-scale fermentation experiments
- Laboratory culture growth and observation
- Process development and method optimization
- Instructional and teaching laboratory setups
- Preliminary testing prior to automated scale-up
- Custom or retrofit bioreactor system builds
Frequently Asked Questions
Is this a complete bioreactor system?
No. This listing includes only the vessel, headplate, frame, and mechanical agitation components shown. No motor, controller, sensors, tubing, or control electronics are included.
Is Sartorius the manufacturer?
No manufacturer markings, model numbers, or serial identifiers are present. Sartorius is referenced only for design similarity and configuration context.
What is the maximum capacity?
The vessel is graduated to 4 liters, which represents the nominal working volume. The total internal capacity exceeds this but has not been measured and should not be assumed beyond visible graduations.
Are the ports sanitary tri-clamp style?
No. The headplate uses threaded ports, consistent with older European laboratory bioreactor designs.
Has the agitation system been tested?
No functional testing has been performed. The agitation shaft and impellers are present, but no drive motor or controls are included.
A straightforward glass reactor from an era when bench-scale systems were built to be adapted, modified, and kept in service. Its next configuration depends entirely on the laboratory that puts it back to work.
