Universal, High Performance Mortar Grinder for Processing of solid materials in dry, wet or

cryogenic condition

• Dry Grinding / Wet Grinding / Ultra Fine Grinding / Cryogenic Grinding
• Mixing
• Cell disruption for DNA / RNA extraction
• The MG100 can handle samples from 10 up to 200 ml

Superior Mortar Grinder engineered to reproducibly grind and mix sample volumes from 10 of up to 200ml.

Method of operation

The Mortar Grinder Model MG 100 is used to reproducibly grind, homogenize and mix a wide range of solid materials in dry / wet or cryogenic condition. The material to be processed falls into the Pulverizing area between Mortar and Pestle by top feeding via the opening which is at the inlet cover. The material is then pulverized and mixed between the Mortar inner surface area and the bottom of the pestle.

In order to match the necessary top pressure with the requested end fineness and the breaking behaviour of the sample to be prepared the MG 100 is equipped with and adjustable Top Pressure Mechanism with scale and a variable speed setting 50-130 rpm and a flexible scraper setting.

Only due to the combination of this 3 key adjustment features a wide range of sample preparation tasks can be reached.

No other grinding system is more easy to clean then the MG 100 Mortar Grinder. When the grinding process is finished the Mortar and Pestle can be taken out with a bayonet lock in order to perform a quick cleaning of the grinding tools.

Grinding, homogenizing, triturating

The Mortar Grinder is the central machine in a sample prep. Laboratory of today. This system is suitable for the fine grinding of any dry substance, as well as for suspensions with different viscosities for analysis, quality control and material testing. It is perfectly suitable for the homogenization of crèmes and pastes. Typically samples with a feed size of up to 8-10mm and a total batch of up to 200 ml (volume depending on the characteristic of the samples) can be ground down to 10-20µm.

High operator convenience and maximum safety

Maximum Grinding performance and maximum safety is important for Laarmann Mills. Due to an integrated safety switch the machine can only be started when the “Easy Lock Cover” is closed. The “Adjustment mechanism” allows the simple and fast settings and fine adjustment.

The cover as well as the housing of the MG 100 is made from solid steel. The ergonomic design of the machine and the front panel ensures the easy and simple setting of all working parameters.
