The Best Lab Orbital Shakers

Key Features to Consider

When selecting a lab orbital shaker, several key features warrant careful consideration to ensure it meets your specific laboratory needs.

• Speed Range: Orbital shakers operate within a defined speed range, typically measured in revolutions per minute (RPM). The required speed depends on the application; some processes need gentle agitation, while others demand vigorous mixing. Ensure the shaker's capabilities align with your experimental protocols.
• Orbit Size: The orbit size, or diameter of the circular motion, influences the mixing intensity. Larger orbits generally provide more vigorous mixing, suitable for larger volumes or denser solutions. Smaller orbits offer gentler agitation, ideal for delicate cultures or smaller volumes.
• Capacity and Platform Size: Consider the types and number of vessels you intend to use. Shakers come with various platform sizes and can accommodate different vessel types, such as flasks, beakers, or microplates. Ensure the platform can securely hold your typical load and that the shaker's capacity matches your throughput requirements.
• Durability and Construction: Look for shakers constructed from robust materials designed for continuous operation. Stainless steel or chemically resistant surfaces are beneficial in laboratory environments where spills or corrosive substances may be present.

Types of Orbital Shakers

Orbital shakers are available in several configurations, each suited for different laboratory tasks.

• Standard Orbital Shakers: These are the most common type, offering a basic orbital motion for general-purpose mixing. They are versatile and suitable for a wide range of applications.
• Incubating Orbital Shakers: These models combine shaking functionality with temperature control, allowing for experiments that require both agitation and a specific incubation temperature. They are ideal for cell culture growth and other temperature-sensitive processes.
• Refrigerated Orbital Shakers: For applications requiring sub-ambient temperatures, refrigerated models provide precise temperature control below room temperature.

Maintenance and Safety

Proper maintenance and adherence to safety guidelines are essential for the longevity and safe operation of any lab orbital shaker.

• Regularly clean the shaker and its platform to prevent contamination and maintain optimal performance.
• Ensure all vessels are securely placed on the platform to prevent spills and accidents.
• Follow the manufacturer's guidelines for operation and maintenance to avoid damage and ensure consistent results.
• Be aware of the maximum load capacity to prevent motor strain or instability.
