OHAUS Multi-Tube Vortexers are ideal for hands-free, high-throughput sample processing. Interchangeable foam racks for vortexing tubes from 10 to 29 mm in diameter are available. Strong suction cup feet reduce motion and prevent sliding on the work surface for safe operation in the lab. Digital models offer exact speed control for applications that demand repeatable results. Non-digital variable speed models are an economical alternative.
