Laboratory Mixers for

Every Need

or more than 30 years, Stir-Pak® and ServoDyne™ overhead stirrers have
helped laboratory scientists with virtually all their mixing and stirring needs.

F

Whether working with relatively simple and straightforward applications
such as water-like solutions, to viscous and precise mixing times or cycles, the
line of Stir-Pak and Servodyne mixers has the answer to your requirements.

Stir-Pak General-Purpose Mixers

Full-range performance at a very
affordable price!

• Highly reliable—perfect for your easy, light-duty mixing needs

• Variable speed from 40 to 4000 rpm

Our general-purpose mixer is ideal for routine mixing of water-like
viscosities. Speed ramps to set speed.

Brushed DC motor has a compact speed controller integrated by
a custom anodized aluminum potentiometer, which controls both
on/off and variable-speed settings for single-direction mixing. LED
light indicates when motor is turned on, or when an overload, over­temperature situation occurs.

Keyless chuck accepts mixing shafts from 5⁄16" to 3⁄8" (8 to 10 mm) dia.

Mixer includes: 3⁄8" (9.5 mm) dia x 12" (305 mm) L, 316 stainless steel

shaft; 11⁄2" (38 mm) dia propeller; 6" (152 mm) mounting rod; and 6-ft
(1.8-m) grounded cord with power supply.

Complete system adds: double clamp and support stand.

Stir-Pak Dual-Shaft Mixer

Ideal for applications with changing
viscosity requirements

• Use for either high-speed or high-torque mixing

• Solid-state controller for precise speed control

Two motor axles give you two mixers in one! The direct-drive axle provides
high-speed, low-viscosity mixing; switch to the gear-reduction axle for your
low-speed, high-viscosity mixing needs.

Rugged, permanent-magnet, totally enclosed nonventilated (TENV) motor has
permanently lubricated ball bearings. Gear-shaft gear ratio is 20:1. Our solid-state
controller maintains speed regulation better than ±2%—critical for materials that
change viscosity as mixing progresses.

Improved torque limiting feature protects against motor gear failure. Controller is
totally enclosed and has an IP24 rating for protection against dust and water; it is
UL-listed and CSA-approved. A 6-ft (1.8-m) cord connects the controller and the
motor.

Keyless chuck accepts shafts from 5⁄16" to 3⁄8" (8 to 10 mm) dia.

Mixer includes: Controller 6" (152 mm) L mounting rod and 6-ft (1.8-m) three-

wire cord with plug.

Complete system adds: 3⁄8" (9.5 mm) dia x 12" (305 mm) L, shaft; 3" dia

(76 mm dia) propeller; double clamp; and support stand.
