Stuart SRT9D Digital 9-Roller Tube Mixer for Biological Samples

The Stuart SRT9D Roller Mixer is a benchtop digital tube mixer engineered for precise and gentle mixing of biological samples including blood, cell suspensions, viscous liquids, and various laboratory solutions. Featuring nine rollers with a 16 mm mixing amplitude and a speed range from 5 to 60 rpm, the unit delivers a combined rolling and slight tilting motion to ensure thorough and homogeneous sample agitation with minimal aeration—*critical for applications such as molecular diagnostics, gene editing workflows, and bioprocessing sample preparation*.

Key technical specifications:

• Digital control system with LCD display shows real-time speed and timer settings, incorporating memory functionality for repeat protocols.
• Supports a maximum load of up to 10 kg distributed across the 340 × 30 mm rollers, accommodating tubes, flasks, and bottles up to approximately 100 mm in diameter.
• Operating conditions compatible with laboratory incubators (up to 60 °C) and cold rooms (down to 4 °C) with humidity up to 80%, suitable for diverse experimental setups.
• Compact footprint (565 × 360 × 110 mm) and relatively lightweight (6.9 kg) for flexible placement in busy biotechnology or clinical diagnostic laboratories.
• Continuous and quiet operation enables long-term use in research environments focused on live-cell imaging, synthetic biology protocols, and biopharmaceutical production pipelines.

This roller mixer is widely adopted in synthetic biology research and essential for molecular cloning workflows where gentle agitation preserves sample integrity, making it a reliable asset in biomanufacturing and molecular biology laboratories.
