Frequently asked questions
What is an overhead stirrer and how does it differ from a magnetic stirrer?
An overhead stirrer uses a motor-driven shaft and impeller to mix liquids, especially suited for higher-viscosity samples or large volumes. Magnetic stirrers use a magnetic field to rotate a stir bar inside the vessel and are generally limited to lower-viscosity solutions and smaller volumes.
How do I choose the right overhead stirrer for my lab?
Consider the viscosity and volume of your samples, the torque needed to mix effectively, and the speed range required. The Ohaus Achiever 5000 series offers models with varying torque and volume capacities to fit different lab applications, from routine mixing to demanding high-viscosity processes.
What are the benefits of digital control in overhead stirrers?
Digital control offers precise speed setting, real-time monitoring via LED displays, and programmable features. This improves reproducibility and reduces human error in critical mixing processes, essential for laboratory consistency.
Are ceramic or aluminum topWhy is torque important in an overhead stirrer? plates better for magnetic mixer hot plates?
Torque measures the stirring force. Higher torque is necessary for mixing viscous liquids or large volumes. Selecting an overhead stirrer with adequate torque ensures smooth operation and prevents motor overload.
How does the Achiever 5000 series ensure safety and durability?
Ohaus Achiever 5000 overhead stirrers include overload protection to prevent motor damage, lock functions to avoid accidental changes, and IP54-rated sealed housings to protect against dust and spills, ensuring long-term reliability in busy labs.
