Stirrer Heads

Rigid, light and unbreakable. The ideal replacement for glass rods.

With R 270 bosshead.

The 4-blade propeller stirrers provide axial flow and create increasing shear forces at higher stirring speeds. Recommended for medium to high speed operations.

The dissolver stirrers create a radial flow with high turbulence. The mixture is drawn from top to bottom. High shear forces are created at the dissolver disk, which provides effective particle reduction. Recommended for medium to high speed operations.

Stainless steel 1.4301. With screwthread fitting as outlined below.

Stable stands with H-shaped base. Stands have a levelling screw to compensate for unevenness on the laboratory bench. Max. load 10 kg.

Powerful Stirring

Shaft diameter: 8mm

Useful extension to the existing range of Bola stirrer shafts. The additional blades can optionally be fixed in your preferred position on every stirrer shaft with diameter 8,10 or 16 mm (a flat spanner is included). The stirrer blades are entirely made of PTFE, the mounting devices are made of a special PTFE-compound. A high chemical and thermical (-200 to +250 °C) resistance is assured. This "building block system" allows the user to define a stirrer of their own special requirements.
