Overhead Stirrer 40W (10L) (100-2500rpm)

An Overhead Stirrer 40W (10L) (100-2500rpm) is a laboratory or industrial device designed for mixing, stirring, and homogenizing liquid samples or suspensions. It operates by suspending a stirring shaft in a container and rotating it at a set speed to achieve uniform mixing. Here's a detailed breakdown:

Key Features:

1. Power Rating (40W):

   • The stirrer is powered by a 40W motor, which provides sufficient torque for mixing liquids up to 10 liters in volume.
   • This power is suitable for moderate to heavy stirring tasks, ensuring that the sample is agitated effectively, especially for liquids with moderate viscosity.

2. Capacity (10L):

   • The device is designed to handle a maximum liquid volume of 10 liters. This makes it ideal for small to medium-scale laboratory applications, such as mixing chemical solutions, biological suspensions, or food products.

3. Speed Range (100-2500 rpm):

   • The stirrer offers a wide range of speeds, from 100 to 2500 revolutions per minute (rpm), allowing for precise control over the stirring process.
   • The speed range makes it versatile, suitable for both gentle mixing (at lower speeds) and vigorous agitation (at higher speeds).
   • Variable speed control allows the user to tailor the mixing speed based on the characteristics of the material being stirred (e.g., for mixing delicate solutions or ensuring thorough blending of viscous substances).

4. Design and Functionality:

   • Overhead Stirring: The motor is mounted above the container, and the stirrer shaft (which can be fitted with various types of mixing blades or paddles) extends into the liquid.
   • The overhead design prevents the stirrer from coming into direct contact with the liquid, which reduces the risk of contamination and allows for the stirring of larger volumes.
   • Safety Features: Many overhead stirrers come with features such as overload protection, automatic shut-off in case of malfunction, or thermal protection for the motor.

5. Applications:

   • Commonly used in laboratories for chemical reactions, cell culture preparation, solution mixing, dissolution processes, and more.
   • Also useful in industries such as pharmaceuticals, food and beverage production, and cosmetics manufacturing.
   • The stirrer is ideal for applications where uniform mixing is essential, including processes involving suspensions, emulsions, or homogeneous solutions.

6. Material Compatibility:

   • The stirrer is typically made of durable materials, such as stainless steel for the motor housing and stirrer shaft, ensuring resistance to chemical corrosion and wear.
   • The stirring elements (e.g., blades or paddles) may be made from materials like PTFE or other chemical-resistant materials depending on the application.

Advantages:

• Versatility: Wide speed range allows for precise control over mixing intensity.
• High Torque: The 40W motor provides enough torque to stir dense and viscous fluids effectively.
• Capacity: Suitable for larger volumes (up to 10L), making it ideal for batch processing in laboratory settings.
• Ease of Use: Simple interface and variable speed control make operation straightforward.
• Space-Efficient: The overhead stirrer design is compact and can be placed on standard laboratory workbenches.

Considerations:

• The motor and stirrer shaft must be cleaned thoroughly between uses to prevent cross-contamination, especially when working with different substances.
• While it can handle liquids up to 10L, very high viscosity materials might require specialized stirring blades or attachments.

In conclusion, an Overhead Stirrer 40W (10L) (100-2500rpm) is a reliable and efficient tool for various laboratory and industrial mixing tasks, offering flexibility in terms of speed control and material compatibility for both simple and complex stirring needs.
