What are the advantages of using a glass fermenter?

Glass fermenters provide excellent visibility, making them ideal for observing microbial or cell culture processes in real time. They are chemically resistant, easy to sterilize, and perfect for research, teaching, and small-scale fermentation experiments.

Are Labtron’s glass fermenters autoclavable?

Yes, Labtron’s glass fermenters are made from high-grade borosilicate glass and are fully autoclavable. This ensures contamination-free operation and easy sterilization between experiments.

What volumes are available for glass fermenters?

Labtron offers glass fermenters in a variety of working volumes, ranging from small benchtop models for lab-scale research to larger pilot-scale systems. Custom volume configurations are also available based on user requirements.

Can I integrate sensors and automation systems with glass fermenters?

Absolutely. Labtron’s glass fermenters support integration with advanced sensors for pH, dissolved oxygen (DO), temperature, and agitation control. They are compatible with digital control systems for automated and real-time bioprocess monitoring.

What industries typically use glass fermenters?

Glass fermenters are widely used in academic research, biotechnology, pharmaceuticals, and food industries. Their precision, transparency, and scalability make them ideal for experimental setups, product development, and training environments.

Glass Fermenter LGF-B12

Name: Glass Fermenter LGF-B12
Brand: Labtron
SKU: LGF-B12
Rating: 4.7 (720 reviews)

Glass Fermenter LGF-B12 features a 5 L double-jacketed borosilicate glass vessel with a stainless steel lid, offering full process visibility. It is equipped with a top-drive mechanical agitator and a six-blade paddle, allowing stable mixing at speeds between 50 to 1000 rpm. Temperature is precisely maintained from +5 °C to 70 °C through an intelligent PID control system using cooling water or electrical heating. Integrated sensors and peristaltic pumps automate pH, DO, and foam regulation for consistent culture conditions.
