Superior Mill engineered for rapid and reproducible sample preparation procedures. The LAB WIZZ can handle simultaneously two or more samples from 0.2 ml up to 160 ml. Grinding, Mixing and Cell Disruption in one machine.

The Laarmann LAB WIZZ is designed for “1001 laboratory applications”. Typical Processing times are between 15 and 45 seconds. The LAB WIZZ can prepare 2 or more samples from 0,2ml of up to 160 ml. It is designed as well for high-sample througput.

High operator convenience and maximum safety

Maximum Grinding performance and maximum safety is important for ESSA Mills. Due to an integrated motor break the machine can only be started when the “Easy Slide Cover” is closed. The unique “Easy Clamp system” allows the simple and safe clamping of all grinding jars up to 160ml.

The integrated stainless steel drawer can be taken off for cleaning purposes.

The grinding chamber, easy clamp system as well as the swinging arm is made from high precision stainless steel to meet all food and pharmaceutical requirements. The housing of the

LAB WIZZ is made from stainless steel as well. Due to the new motor concept and a direct motor drive, the Laarmann LAB WIZZ is maintenance free.

Advantages

Due to the unique combination of a wide range of grinding jars of various materials the LAB WIZZ is capable to practically meet all demands of today’s laboratory needs.

This mainly include:

Grinding (wet and dry) / cell disrup- tion / mixing XRF Prep / turbulent blending (Static Mixer) and cold grinding.

Due to the combination of high energy vibration and the punch of the grinding balls the LAB WIZZ cannot only grind hard and brittle materials but as well all medium soft, soft materials and elastic materials.

Features

-Universal and highly efficient grinding, blending and disruption
-Large range of grinding jars and accessories
-Large range of grinding balls and accessories
-Extremely short processing times
-Designed for high sample throughput
-Reproducible results by digital pre-setting of all working parameters

Fast clamping jars for grinding applications

• Dry grinding

• Wet Grinding

• Ultra Fine Grinding

• Mechanical alloying

Grinding jars for Static Mixing applications

All LAB WIZZ Static Mixers, have some helical mixing element which directs the flow of material radial toward the pipe walls and back to the centre. Additional velocity reversal and flow division results from combining alternating right- and left-hand elements, thus increasing mixing efficiency. All material is continuously and completely mixed, eliminating radial gradients in temperature, velocity and material composition.

• Turbulent Blending

• Laminar Blending

• Liquid Dispersion

• Gas Liquid Dispersion

Micro vial holder for cell disruption

Designed for high analytical screening, the LAB WIZZ efficiently and safely disrupts samples of spores, microorganisms, plant and animal tissue or soil samples at a time.

The samples along with extraction media and small metallic or ceramic balls are placed in micro vials. After 2 minutes of preparation in the LAB WIZZ more than 95% of the cells are disrupted. Because balls and vials plates are disposable the method is ideal for PCR, PAGE, and Probe applications where cross contamination between samples cannot be tolerated.

Stainless steel Micro vials

Stainless steel Micro vials are used for cryogenic grinding of small sample amounts or for standard grinding applications of small samples such as soil or grain using a steel or tungsten carbide bead.

Steel vials ensure a much higher heat transformation in order to optimize the heating and cooling.

The stainless steel Micro vials are available with a grinding ball pre-filling optional.

Ice bath for cryogenic grinding

For heat sensitive materials such as plastics and rubber it is possible to embrittle the material with liquid nitrogen and 

perform an additional external freezing of the fast clamping jars. Those jars are either made from Teflon or from stainless steel and are suitable for cryogenic grinding applications.
