Laboratory Stirrers Comparison Chart
Overhead stirrersconsist of a stirring fixture, or stand, a digital controller, a drive shaft, and a motor for mixing viscous solutions. Overhead stirrers are used for a broad range of mixing applications including tissue grinding, cell media preparation, wastewater purification, formulation of polymers, adhesives, and coatings.
Optional lab stirrer accessories include propeller blades, dissolvers, head clamps, manual chucks, telescoping stands, and shaft protectors.
Factory-fitted quick adapters, or chucks, support quick shaft replacement for labs processing a wide range of sample viscosities.
Digital controllersinclude programmable functions, overload protection alarms, mixing speed adjustment, data export and third-party software integration.
A - Application
(back to chart)
A1 - General Mixing
General overhead mixing stirrers, such as theIKA EUROSTAR 40models, are ideal for mixing low viscosity liquids below 7,000 mPas (millipascal-seconds). Applications include cell media preparation or soft tissue grinding for drug development.
A2 - High Viscosity Liquids
High-viscosity overhead stirrers, likeIKA’s EUROSTAR 100,包括可互换的叶片和驱动轴to ensure thorough stirring or homogenization. Ideal for mixing solutions above 7,000 mPas (millipascal-seconds), such as polymers, plastics, adhesives, glues and coatings.
B - Maximum Speed
(back to chart)
Listed in revolutions per minute (rpm), standard overhead stirrers carry a user-adjustable mixing speed range between 30 – 1,500 rpm. However, high-speed models, such asIKA’s EUROSTAR 20, maintain speeds up to 2,000 rpm for low-volume mixing (under 15 ml).
C - Maximum Viscosity
(back to chart)
Max-viscosity stirrers, likeIKA’s EUROSTAR 200, are designed to mix solutions up to 150,000 mPas. The dynamic viscosity, reported in millipascal-seconds (mPas), refers to the thickness of the fluid during mixing. As batch solutions may increase in viscosity during the stirring process, the maximum viscosity specification of the overhead stirrer must meet or exceed the highest attainable dynamic viscosity of the solution.
D - Lab Stirrer Capacity
(back to chart)
Capacity refers to the maximum volume of fluid, reported in liters, safely and effectively mixed by the overhead stirrer. Unless otherwise noted in the manufacturer specifications, the maximum volume assumes the liquid to be water.
High-volume overhead stirrers, likeIKA’s RW47, are designed to homogenize up to 200 liters of fluid.
E - Application-Specific Lab Stirrer Features
(back to chart)
E1 - Wireless Lab Stirrer Controller
IKA’s EUROSTAR overhead stirrersinclude a wireless digital controller featuring automatic speed adjustment, programmable functions, multilingual display, timed interval operation, lock/unlock modes, and integrated temperature measurement.
E2 - Reversible Stirring
Reversible stirring models, likeIKA’s EUROSTAR 100, are designed to rotate the stirring shaft in clockwise (standard) and counter-clockwise (reversible) directions. For highly-viscous solutions, reversible stirring ensures the fluid is thoroughly mixed.
E3 - Lab Stirrer Overload Protection
Stirrers with overload or overheat protection, likeIKA’s EUROSTAR 60, automatically shut down if conditions fall outside of the operating range. Overload protection guards the motor and electronics from heat-related damage during continuous-duty mixing.
E4 - Lab Stirrer Software Integration
Digital overhead stirrers, likeIKA’s EUROSTAR 200, include controllers with data export functions compatible with third-party software, such as laboratory information management systems (LIMS). Password-protected profiles and secure data export operations are optimal for cGMP facilities.
