Plastic dispersing heads: Autoclavable
Stainless steel dispersing heads: Ultimate fineness emulsions 1 to 10 µm and suspensions 10 to 50 µm, sterilisable by all methods.

High speed laboratory stirrer designed for intensive stirring tasks for quantities up to 20l (H2O). It automatically adjusts the speed through microprocessor controlled technology within the speed range of 0/150 to 6000rpm. Safety circuits installed ensures automatic cut-off in an anti-stall or overload conditions. Continuous comparison of shaft speed to desired speed is maintained and variations are adjusted automatically. This guarantees a constant speed even with changes in viscosities of the sample.

The anchor stirrers create a tangential flow and high shear forces between the vessel wall and stirring blades. Especially suitable for medium to high viscosity fluids. Recommended for low speed operations.

Suitable for disposable and reusable grinding chambers. By using the disposable grinding chambers the possibility of cross-contamination and the effort of cleaning is eliminated. The mills can be used for hard (Mohs hardness up to 5), dry and brittle materials. They are especially suitable for grinding seeds, such as corn and wheat. Increased safety, the operation of the mill is only possible with properly closed grinding chamber and closed lid.

Generates a radial flow. For drawing the material to be mixed from the top and bottom. For aerating of low viscosity media and for homogenizing solids in liquids. Used at medium to high speeds.

The folding blades of this 2-blade centrifugal stirring rotor open with increasing speed, allowing use with narrow-neck vessels. The stirring effect it provides is similar to a standard diagonal blade stirring rotor. Recommended for medium to high speed operations.

Due to the material separation at medium speeds, this midi centrifuge is ideal for all types of separation processes, such as in molecular biology. It can be used with standard 1.5 / 2 ml tubes as well as with PCR strips. The cover opens automatically at the press of a button.

• High-performance motor
