Product description

Robust 3L benchtop bioreactor with advanced pH, DO, temperature control for scalable bioprocess development.

The Sartorius BIOSTAT STR 3 is a precise benchtop bioreactor system designed for microbial and mammalian cell cultivation with a working volume of up to 3 liters. It delivers advanced bioprocess control including real-time monitoring of critical parameters such as pH, dissolved oxygen (DO), temperature, and agitation speed. Equipped with *WinISO v9.xx* software on an intuitive touch screen interface, the system facilitates streamlined process management and data acquisition essential for biotechnology research and development workflows.

Key features include:

  • Integrated sensors for pH, DO, and temperature measurement ensuring reliable parameter regulation critical in molecular diagnostics and synthetic biology applications.
  • Modular accessory compatibility, including peristaltic pumps, gas mixing units, and agitator modules, supporting scalable bioprocesses from lab research to pilot-scale biomanufacturing.
  • Compact design (20 × 17 × 17 inches, 66 lbs) ideal for spatially efficient laboratory environments focused on cell imaging, bioprocess development, and biopharmaceutical production pipelines.
  • Robust software control enabling consistent and reproducible cultivation results, widely used by researchers in bioprocessing, gene editing, and biotechnology sectors.

This bioreactor system is critical for researchers and professionals conducting cell culture experiments, live-cell bioprocess monitoring, and scalable microbial fermentation, making it a popular choice in biomedical engineering and biotech research environments.

Why Questpair exists

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.

We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.

We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Yes. Every verified supplier states which service partners cover the instrument, and we list that alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
