Mixers and Rockers

Lab Mixers, Rockers & Benchtop Mixing Equipment

How do I choose between an adjustable speed and a fixed speed lab mixer?

Your choice depends entirely on the variety of protocols you perform daily. Consider these key factors before purchasing:

• Adjustable models: These versatile units allow you to change the agitation rate. They are ideal for shared facilities handling highly diverse sample types.

• Fixed models: These devices maintain a constant rotation or shaking rate. They are highly effective for standardized clinical procedures where the required protocols never change.

What is a tube roller used for, and how is it different from a vortex mixer?

These two instruments serve very different sample preparation needs:

• Tube rollers: These devices provide continuous, slow horizontal rotation. They are commonly used for clinical blood collection tubes to prevent sample coagulation without damaging fragile cellular components.

• Vortex devices: These units deliver high speed, aggressive vertical agitation. They are designed to rapidly resuspend small pellets or thoroughly combine liquids in small centrifuge vials.

What lab mixer should I use for viscous samples or suspensions?

Thick liquids require high torque motors to ensure thorough blending. Standard microplate units might stall or overheat under heavy liquid loads. For these challenging applications, we recommend heavy duty models. Devices like the Ohaus Heavy Duty series provide the necessary power to process highly resistant materials safely. These specialized tools keep your workflow moving without burning out the internal motor components.

What RPM or speed range do I need for a laboratory vortex mixer?

The required rotation rate depends entirely on your specific applications:

• Low range: Speeds around 100 to 500 RPM work well for gentle fluid agitation and basic blending tasks.

• High range: Speeds exceeding 2000 RPM are necessary for breaking up tightly packed cell pellets quickly.
  Many multi tube and single plate units offer broad operating ranges to accommodate both gentle and aggressive blending requirements in one footprint.

Can laboratory mixers and rockers be used inside an incubator or cold room?

Yes, many devices are engineered specifically for extreme temperature environments. However, you cannot use just any standard unit in these harsh conditions. Look for models explicitly rated for high humidity or extreme cold. For example, specific Benchmark Scientific 3D rockers and incubator shakers feature sealed internal components. This protective design resists moisture buildup and prevents internal damage during extreme temperature fluctuations.

Can I get a quote for multiple lab mixers or rockers for my facility?

Yes, we frequently help facilities outfit their entire workspaces. Our team is ready to assist you with bulk pricing and specialized equipment packages.
