Mortar Grinder RM 200

For efficient and contamination-free grinding processes, mortar and pestle are available in 7 different materials (no undesired abrasion):

• Hardened steel (density 7.6 g/cm³; hardness ≤ 250 HB, medium abrasion resistance):
  typically used for pulverizing medium-hard to hard and brittle samples
  
  
• Stainless steel (density 7.7 g/cm³; hardness ≤ 245 HB, medium abrasion resistance):
  typically used for pulverizing medium-hard to hard and brittle samples. Stainless steel is also used for homogenizing frozen yeast cells.
  
  
• Tungsten carbide (density 14.8 g/cm³; hardness 93.6 HRA; high abrasion resistance):
  used for grinding very hard, brittle sample materials. By using tungsten carbide, contamination of the sample with iron is prevented.
  
  
• Agate (density 2.65 g/cm³; hardness 6.5 – 7 Mohs, low abrasion resistance)
  a highly pure natural material suitable for pulverizing soft to medium-hard or fibrous samples.
  
  
• Sintered aluminum oxide (density 3.9 g/cm³; hardness 1750 HV, medium abrasion resistance):
  a ceramic material suitable for grinding soft to medium-hard or fibrous samples. It is mainly used for heavy-metal-free grinding processes.
  
  
• Zirconium oxide (density 6.05 g/cm³; hardness 1250 HV, high abrasion resistance):
  a ceramic material suitable for pulverizing medium-hard to hard and fibrous samples. It is typically used for heavy-metal-free grinding processes.
  
  
• Hard porcelain (density 2.4 g/cm³; hardness 1200 HV, high abrasion resistance):
  a ceramic material suitable for grinding medium-hard to hard or fibrous samples. It is mainly used for heavy-metal-free grinding or pharmaceutical samples.
  
  

Please note:

The grinding tool material should be harder than the sample. For further information on materials please see the document “Material Analyses of Equipment & Accessories“ in the Downloads section.

Three different scrapers are available.

The scraper made of polyurethane (PU) is the standard. The beech wood scraper is especially suitable for pharmaceutical applications. The PTFE scraper is used for cryogenic applications.
