Stuart SB161-3 Multi-Position Magnetic Stirrer with 3 Independent Stirring Points, 100–1500 rpm

The Stuart SB161-3 magnetic stirrer is a precision-engineered *multi-position magnetic stirring device* featuring three independent stirring points, each with its own variable speed control ranging from 100 to 1500 rpm. This versatile instrument is designed to facilitate simultaneous mixing of multiple samples, making it essential for workflows requiring parallel processing in chemical, biological, pharmaceutical, and bioprocessing laboratories.

• Three individually adjustable stirring positions allow tailored speed control for distinct sample requirements.
• Each stirring position supports a maximum volume of approximately 1 liter of aqueous solution, suitable for tasks such as buffer preparation, solution mixing, cell culture media homogenization, and routine analytical sample processing.
• The stirring surfaces are made of aluminum alloy with a chemical-resistant coating, ensuring durability and easy cleaning, suited for daily laboratory usage.
• Compact design with overall dimensions around 450 × 190 × 90 mm and a weight of approximately 4.5 kg ensures stability and portability.
• Operates on a 230 V, 50/60 Hz power supply and features a robust metal housing with non-slip feet and IP32 protection class, providing electrical safety and operational stability.

This magnetic stirrer is widely used in molecular diagnostics, synthetic biology, and biomanufacturing laboratories, supporting critical applications like parallel reaction mixing, live-cell media preparation, and routine sample homogenization. It is particularly valued in biotechnology research for its reliability in multipoint mixing scenarios essential in gene editing protocols, bioprocessing steps, and other biomedical engineering tasks.

The Stuart SB161-3 is tested, in excellent condition, and ready to integrate seamlessly into advanced laboratory workflows demanding consistent stirring performance across multiple samples.
