Frequently Asked Questions
1. When should I choose an overhead stirrer over a magnetic stirrer?
An overhead stirrer is necessary for high-viscosity liquids or large volumes where a magnetic stir bar would lose "coupling." They offer more power and allow for different impeller shapes to suit specific mixing patterns.
2. What is the benefit of a digital hotplate stirrer?
Digital models allow for precise temperature and speed settings, often featuring feedback control via external sensors. This ensures that your sample stays at the exact temperature required, which is critical for sensitive chemical reactions.
3. Do I need a specific shaker for cell culture applications?
Yes, for cell culture, an orbital shaker with gentle motion and low CO2/humidity resistance is often required. These are designed to be placed inside incubators to provide continuous aeration and nutrient distribution without damaging cells.
4. How do I choose the correct impeller for my overhead stirrer?
The choice depends on the desired flow: propeller impellers create axial flow for general mixing, while anchor or paddle impellers are better for high-viscosity fluids or preventing sedimentation at the bottom of the vessel.
5. Are vortex mixers suitable for continuous operation?
While most vortex mixers are designed for short "touch" bursts to quickly mix small tubes, many of our professional models feature a "continuous" mode for use with plate or tube-rack attachments for longer mixing periods.
6. How do I choose the best laboratory mixer or stirrer for my specific application?
