KINEMATICA POLYMIX® Overhead Stirrer PX SR 90 D

Ideally suited for quality control, research, and industrial laboratories, KINEMATICA POLYMIX are the perfect overhead stirrers for mixing, dispensing, and stirring applications in almost any vessel up to 25 liters. Available in either analog or digital models, this new benchtop series carries the safety-certified CE mark and the latest safety features, including an integrated antiblocking mechanism, built-in overheating protection, and a sturdy, nontilting stand. A complete line of stirring rods and accessories for different samples is available.

Areas of application

  • Mixing, dispensing, and stirring applications in almost any vessel up to 25 liters
    • Dissolving tablets and other solids in solvents
    • Tissue grinding of small samples
    • Stirring viscous solutions to achieve a homogeneous mixture
    • Mixing heat-sensitive samples with minimal shear force
  • Ideally suited for quality control, research, and industrial laboratory settings

Product features

  • Choice of digital or analog rpm speed control
  • High-torque motor for viscous samples and demanding applications
  • Selectable rotational direction for various sample properties
  • Overload protection indicator helps to protect motor from excessive wear and tear
  • Sturdy space-saving stand with support rod for safe, convenient benchtop use
  • A complete line of stirring rods and accessories for different samples is available

Stirrers and mixing aggregates/applications chart

Stirrers and mixing aggregates Applications
Stir Propeller with 4 blades For standard applications that require axial flow and low shear forces
Stir Propeller with 3 blades For applications that require strong flow and low shear forces
Turbine Stirrer For applications that require top-down suction and low shear forces
Dissolving Stirrer For applications that require high turbulence, shear forces, and particle crushing
Centrifugal Stirrer with 2 variable blades For the mixing of samples in narrow-neck bottles that requires low shear forces—propellers spread out as speed increases
Paddle Stirrer For applications involving sensitive samples that require low turbulence and low heat generation
Anchor Stirrer For applications involving highly viscous samples that require high shear forces concentrated at the outer diameter of the stir blade
Kneading Stirrer For applications involving low-to-medium-viscous samples that require low shear forces concentrated at the outer diameter of the stir blade
Tissue Grinder/Mortar* For homogenizing small amounts of tissue, cells, and bacteria (requires no solvent for disruption)

*Each model includes choice of: 2 ml, 5 ml, and 15 ml sample vessels; or 2 ml, 5 ml, and 15 ml water-cooled sample vessels for temperature-sensitive samples
