Karıştırıcı Kafaları

With R 270 bosshead.

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

The stirrer shafts consist of a PTFE-jacketed, stainless steel shaft and a stirrer paddle made of solid PTFE. The stainless steel core assures stability of the stirrer shaft and allows safe attachment of the stirrer chuck. Thanks to the thick PTFE coat and the paddle made of solid PTFE, the medium will only come into contact with PTFE. High chemical resistance makes it almost universally suitable. PTFE is extremely nonstick so that residues are repelled from shaft and paddle. The stirrer shafts are similar in size to (KPG) glass stirring rods and are therefore interchangeable easily.

Operating temperature: -200°C to +250°C

Additional sizes and accessories are available on request.
Information on the mixing effects of the different stirring geometries can be found in the descriptions of the stainless steel stirring rotors.
The semi-circular shape of the paddle is ideal for mixing in round-bottom flasks. The pivoting blade allows insertion into vessels with narrow necks and/or ground joints.

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.

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

Blade and Half-Moon Impeller

• These impellers are recommended for applications which require an average speed
• For mixing products with average viscosity
• Models BR 12, BR 14 and HR 18 come with collapsible blade for narrow neck vessels

• These impellers are recommended for applications which require an average or high speed
• For mixing products with medium or high viscosity
• Excellent mixing properties for homogenisation and suspensions
• These models create an axial flow

• These impellers are recommended for applications which require an average speed
• For mixing products with average viscosity up to <500mPas
• Ideal for gassing of liquids
• These impellers create a radial flow

• These impellers are recommended for applications which require a low speed
• For mixing products with medium or high viscosity

The paddle stirring rotor creates a tangential flow with minimum turbulence. Its design ensures a gentle action on sensitive products and good heat exchange. Recommended for low to medium speed operations.
