Speed Range: 60–400 rpm / 30–2,000 rpm
Floating Blade
Blade (mm): 93 × 11
Shaft Ø (mm): 7
Shaft Length (mm): 400
Speed Range: 250-Max
Viscosity Range: 0-100 / 100-1,000
Flow Pattern: Radial
Description: Floating Blades align during stirring and create radial flow from top to bottom in the vessel. This blade is ideal for stirring in narrow neck vessels
Fixed Blade
Item Number: 30586776
Blade (mm): 50 × 10
Shaft Ø (mm): 7
Shaft Length (mm): 400
Speed Range: 250-Max
Viscosity Range: 0-100 / 100-1,000 / 1,000-10,000
Flow Pattern: Radial
Description: Fixed Blade creates radial flow from top to bottom in the vessel. Ideal for use at medium to high speeds for stirring light solids, mixing thickening materials, flocculation, etc.
Folding Blade
Item Number: 30586778
Blade (mm): 60 × 15
Shaft Ø (mm): 7
Shaft Length (mm): 400
Speed Range: 250-Max
Viscosity Range: 100-1,000 / 1,000-10,000
Flow Pattern: Radial
Description: Folding Blade aligns during stirring and creates radial flow from top to bottom in the vessel. This blade is used for stirring in narrow neck vessels.
Turbine
Item Number: 30586781
Blade (mm): 49 × 10
Shaft Ø (mm): 7
Shaft Length (mm): 400
Speed Range: 250-Max
Viscosity Range: 1,000-10,000 / 10,000-100,000
Flow Pattern: Radial
Description: Turbine creates a high shear, high turbulence radial flow in the vessel. This flow is from top to bottom.
Propeller
Item Number: 30586780
Blade (mm): 60 × 9
Shaft Ø (mm): 7
Shaft Length (mm): 400
Speed Range: 250-Max
Viscosity Range: 0-100 / 100-1,000 / 1,000-10,000
Flow Pattern: Axial
Description: Propeller creates axial flow with limited shearing forces. This flow pulls the sample from top to bottom in the vessel.
Turbo Propeller
Item Number: 30586782
Blade (mm): 46 × 14
Shaft Ø (mm): 7
Shaft Length (mm): 400
Speed Range: 250-Max
Viscosity Range: 1,000-10,000 / 10,000-100,000
Flow Pattern: Axial
Description: Turbo Propeller creates a low shearing axial flow in the vessel. This flow pulls the sample from top to bottom and the ring limits the contact of the blade with walls of the vessel or probes.
Paddle, 6 Holes
Item Number: 30586779
Blade (mm): 69 × 75
Shaft Ø (mm): 7
Shaft Length (mm): 510
Speed Range: Up to 800
Viscosity Range: 100-1,000 / 1,000-10,000
Flow Pattern: Tangential
Description: Paddle creates a reduced turbulence radial flow in the vessel producing gentle mixing of the sample.
Anchor
Item Number: 30586775
Blade (mm): 45 × 54
Shaft Ø (mm): 7
Shaft Length (mm): 400
Speed Range: All Speeds
Viscosity Range: 1,000-10,000 / 10,000-100,000
Flow Pattern: Tangential
Description: Anchor creates tangential flow with high shearing forces on the ends. This flow can prevent sedimentation on the walls of the vessel.
