Screw-top grinding jars are dust- and air-tight which makes them suitable for dry, wet and cryogenic grinding. Moreover, they safely enclose inert atmosphere, for example after the jar was filled inside a glove box.

Always select a grinding jar size suitable for the sample volume (approx. 30% of the jar is filled with sample material). Grinding jars are provided in sizes ranging from 1,5 ml to 50 ml (not all sizes available in all materials).

The document “Grinding Jar Ball Charge” in the Downloads section provides details about usable volumes, maximum feed sizes and correct filling of the jars with grinding balls for dry and wet milling as well as cell disruption.

For efficient and contamination-free grinding processes the grinding jars are available in 6 different materials (no undesired abrasion).

The energy input increases with the density of a material. For pulverizing soft samples, materials with a low to medium density should be used, whereas for hard samples it is better to use high-density materials.

Available materials:

  • Hardened steel (density 7.8 g/cm3; hardness ≤ 235 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. 

  • 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 2.6 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. Due to its low-density agate is suitable for gentle grinding processes with low energy input. 

  • Zirconium oxide (density 6.05 g/cm3; hardness 1250 HV, high abrasion resistance) 
    ceramic material suitable for pulverizing medium-hard to hard and fibrous samples. It is typically used for heavy-metal-free grinding processes or applications which aim at ultrafine particle sizes.

The conical centrifuge tubes are perfectly suitable for mixing powders or liquids, e. g. for the extraction of pesticide residues with the QuEChERS method.

They can also be used for enzyme extraction from cell suspensions – up to 8 x 30 ml cell suspension are disrupted in one step. Soft tissue like liver may also be homogenized in these tubes.

For biological applications like cell disruption or homogenization of small tissue samples a variety of single-use vials are available. For cell disruption glass beads are the best choice.

The document “Grinding Jar Ball Charge” in the Downloads section provides details about usable volumes, maximum feed sizes and correct filling of the jars with grinding balls for dry and wet milling as well as cell disruption.

Toebehoren voor koude vermaling MM 400

For cold grinding (cryogenic grinding) we recommend using the Cryo kit which consists of two pairs of tongs, two insulated containers (1 & 6 liters) as well as a pair of safety goggles.
Please only use grinding jars of hardened or stainless steel for cryogenic grinding. When using jars made of other materials, inner tension may build up and lead to damages of the jar under extreme temperature variations.

Attention:

First, the jar is filled with sample and ball(s), then the lid is screwed tightly, and the jar is immersed with the tongs in the container filled with liquid nitrogen. After a few minutes (the liquid nitrogen should no longer boil) the sample has been indirectly embrittled inside the jar which can now be removed with the help of the tongs and clamped into the mill. Please never fill liquid nitrogen into the grinding jar because it evaporates and causes a considerable overpressure inside the jar.

Grinding balls and grinding jars should always be selected from the same material.

Grinding balls are available in different diameters. The rule of thumb is: for efficient milling the ball should be at least 3 times larger than the largest particle in the sample. To avoid abrasion and wear it is essential to only use balls with identical diameter.

The number of grinding balls depends on the jar volume used. The document “Grinding Jar Ball Charge” in the Downloads section provides details about usable volumes, maximum feed sizes and correct filling of the jars with grinding balls for dry and wet milling as well as cell disruption. For further information on materials please see the document “Material Analyses of Equipment & Accessories“ in the Downloads section.

  • Hardened steel (density 7.8 g/cm3; hardness ≤ 235 HB, medium abrasion resistance) 
    typically used for pulverizing medium-hard to hard and brittle samples.

  • Glass beads are suitable for applications like cell disruption, for example of yeast, bacteria or microalgae. For yeast larger glass beads are best suited whereas microalgae require small beads. Glass beads are also used for washing bacteria off surfaces or tissue samples for subsequent diagnosis.
