Laboratory Equipment: A Guide to Mixer Selection

When choosing laboratory equipment such as a mixer, several variables should be considered specific to your application. For mixers, gather the follow information:

Stir-Pak High-speed, Low-Torque Mixer System (23-2300rpm, 115 VAC)

• What container capacity do you need?
• What liquid viscosity?
• What are your torque requirements?
• What are your horsepower requirements?
• What rotational speed or RPM do you need? What diameter for the mixing propeller?
• What are your requirements for duty cycle?
• What will be the source of your power supply?

Laboratory Mixers are available with permanent magnet, universal, or air-drive motors. Choose different mixer mounts for mounting on tanks or stands. A variety of impellers and paddles lend versatility to the mixer you select.

Industrial Mixers are available with electric- or air-driven motors for up to 1-hp. Fixed- or variable-speed and direct- or gear-driven options are available.

Specialty Mixers include:

Sanitary Mixers for all applications requiring extra clean processes.

Bulk-Container Mixers mount atop tote containers and mix liquids that are in long- or short-term storage.

Handheld Mixers for mixing thin or heavy liquids in open or closed containers.

Static Mixers are installed inline and mix fluids as you pump them through a pipeline. The fluid moves through the mixer in an alternating clockwise/counterclockwise motion to ensure a homogeneous product. They are virtually maintenance free and need no spare parts.
