Multi-Position Magnetic Stirrers for High-Throughput Applications
These multi-position magnetic stirrers deliver synchronized and uniform mixing across multiple samples simultaneously. Available in four-position and nine-position configurations, these powerful stirrers feature microprocessor-controlled speed regulation for repeatable performance. Choose between digital models with touchpad controls or non-digital models with adjustment knobs to suit your laboratory workflow requirements.
Key Product Advantages
The 318 x 279 mm glass-filled nylon top plate provides a chemical-resistant work surface with reflective white color that minimizes unintended sample heating. The generous platform accommodates up to 9 x 250 mL flasks or 4 x 1 L flasks depending on model selection.
Speed ramping functionality gradually increases motor speed for enhanced coupling and improved stirring safety. This feature prevents splashing, improves spin bar control, and provides excellent low-end speed control for sensitive applications.
Digital models offer touchpad controls for precise input of speed and time parameters. Non-digital models utilize an adjustment knob with dial markings from 1-10. All models employ microprocessor regulation to maintain consistent speed adjustments throughout the operating range.
