Stuart SB1 Tube Rotator with 20-Place Rotor Holder for Sample Mixing and Incubation

The Stuart SB1 Tube Rotator is a versatile benchtop tube mixer designed for gentle and continuous rotation or tilting of up to 20 sample tubes, ranging from 1.5 ml to 50 ml in volume. Engineered for applications such as incubation, suspension mixing, and antibody protocols, it ensures homogeneous sample agitation critical in molecular diagnostics and bioprocessing workflows.

Key features include:

• Dual rotation modes: continuous tilting or peanut-shaped rotation to optimize mixing efficiency
• Capacity: accommodates 20 tubes simultaneously, ideal for parallel processing in cell culture and synthetic biology research
• Robust motor: quiet, durable drive providing approximately 20 rpm for stable mixing without vibration
• Secure rotor holder: engineered for uniform sample movement, minimizing sample sedimentation and shear stress
• Compact dimensions: 220 × 140 × 120 mm footprint and lightweight 2.0 kg design, suitable for routine laboratory benchtops
• Material construction: metal housing with plastic rotor grip free of medical-grade PTFE or Teflon, ensuring chemical resistance and biocompatibility
• Power supply: standard 230 V, 50 Hz compatible with typical lab infrastructure

Widely adopted in biochemistry, microbiology, and biotechnology laboratories, the Stuart SB1 supports live-cell imaging sample preparation, antibody binding assays, and molecular cloning protocols. Its reliable performance is particularly valuable in biomanufacturing processes requiring consistent and gentle mixing of cell suspensions and reagents.

Designed for easy assembly, maintenance, and cleaning, this tube rotator is a practical solution for daily use in clinical diagnostics and bioprocess development environments.
