Digital overhead stirrers for controlled laboratory mixing — from routine low-viscosity workflows to advanced formulation tasks and direct GL-45 bottle mixing.
The Yellow Labware IMS overhead stirrer range is built for stable, repeatable and practical laboratory mixing. Choose a compact efficient-torque system for daily liquid preparation, step up to programmable bidirectional control, or select the right IMS model according to speed range, viscosity, volume and workflow requirements.
Each IMS model is positioned for a different laboratory mixing need, from efficient torque operation to advanced controlled stirring and GL-45 direct bottle mixing.
Precise laboratory mixing for liquids and low-viscosity materials.
IMS-01 is the clean entry point of the IMS range, designed for stable digital mixing in routine laboratory workflows where controlled speed, compact integration and repeatability matter.
Efficient torque overhead stirrer with touchscreen control, recipe support and bidirectional stirring.
IMS-02 adds workflow intelligence to efficient torque mixing with recipe/recall mode, audible buzzer support and CW/CCW direction control for repeatable protocols.
High torque overhead stirrer with touchscreen control.
IMS-03 is built for stronger mixing performance in more demanding laboratory conditions, especially when working with higher viscosity samples or larger mixing volumes.
Advanced overhead stirrer with wide speed range and controlled laboratory operation.
IMS-04 is designed for controlled mixing workflows that require a wider speed range, digital operation and reliable performance for routine to advanced laboratory applications.
Direct bottle overhead stirrer for GL-45 laboratory bottles.
GL-45 is designed for compact, closed-container mixing in standard GL-45 laboratory bottles, reducing footprint and supporting safer direct bottle workflows.
Compare the IMS range by control features, speed range, torque class, viscosity support, stirring volume and workflow fit.
