Please note: For the Planetary Mono Mill PULVERISETTE 6 classic line, you require at least 1 grinding bowl of your choice and the corresponding number of grinding balls. The grinding bowl material must also be harder than the material to be ground. In normal cases, grinding bowls and balls of the same material are used. To shorten the grinding time, grinding bowls and balls with a higher density and correspondingly higher impact energy can be used. Please take note of the useful capacity, this is not identical with the bowl volume!

For the Planetary Micro Mill PULVERISETTE 7 premium line/classic line / Planetary Mill PULVERISETTE 6 premium line / Planetary Mill PULVERISETTE 5/2 classic line / Vario-Planetary Mill PULVERISETTE 4 classic line, you require at least 2 grinding bowls of your choice and the corresponding number of grinding balls. The grinding bowl material must also be harder than the material to be ground. In normal cases, grinding bowls and balls of the same material are used. To shorten the grinding time, grinding bowls and balls with a higher density and correspondingly higher impact energy can be used. Please take note of the useful capacity, this is not identical with the bowl volume!

For the Planetary Mill PULVERISETTE 5/4 classic line, you require at least 4 grinding bowls of your choice and the corresponding number of grinding balls. The grinding bowl material must also be harder than the material to be ground. In normal cases, grinding bowls and balls of the same material are used. To shorten the grinding time, larger or heavier grinding bowls and grinding balls with a higher density and correspondingly higher impact energy can be used. Please take note of the useful capacity, this is not identical with the bowl volume!

 

For achieving best grinding results grinding balls are available in 0.1 - 15 mm/20 mm/40 mm diameters and in 7 different materials, thus directly preventing contamination of the samples as a result of undesired abrasion. The recommended number of balls per grinding bowl can be found in the selection aid.

 

For the Mini-Mill you require 1 grinding bowl and the corresponding number of grinding balls. To avoid undesired contamination of the sample through abrasion, we offer a selection of 4 different material types. Normally, grinding bowls and balls of the same material are used. In principle, the grinding bowl material must be harder than the material to be ground. 
Grinding bowls and grinding balls made of zirconium oxide for absolute metal-free grinding are also offered. Important: please keep in mind the specified useful capacity as this is not identical to the bowl volume.

For achieving best grinding result grinding balls are available in ≤ 3 mm - 15 mm diameters and in 4 different materials, thus directly preventing contamination of the samples as a result of undesired abrasion. The 5 ml PTFE bowl is especially suited for biotechnology applications. The recommended number of balls per grinding bowl can be found in the selection aid.
It may also be useful to work with grinding balls ≤ 3 mm diameter. We have not listed these here because we would like to advise you personally regarding this application. Please contact Leos Benesour laboratory manager.

 

General material specification:
Material: zirconium oxide - ZrO2
Abrasion resistance: very good
Suitable for: fibrous, abrasive samples

 

100 grinding balls made of zirconium oxide with 5 mm dia. weigh approx. 38 g. With the weight information, the high number of balls per grinding bowl can be determined by weighing.

ADDITIONAL INFORMATION

Grinding balls with diameter 3 mm and smaller must be weighed out. The above table provides you with the necessary weight to be included per grinding bowl.

The quantity of grinding balls can be reduced by up to 15 %; however, increased wear can then be expected. The specified number/mass of balls per bowl is the minimum quantity; depending on the material behaviour, it may be necessary to increase this.

In normal cases, grinding bowls and balls of the same material are used. To shorten the grinding time, grinding bowls and balls with a higher density and correspondingly higher impact energy can be used.

To shorten the grinding time, grinding bowls and balls with a higher density and correspondingly higher impact energy can be used. Please take note of the useful capacity, this is not identical with the bowl volume!

For the Planetary Micro Mill PULVERISETTE 7 premium line/classic line / Planetary Mill PULVERISETTE 6 premium line / Planetary Mill PULVERISETTE 5/2 classic line / Vario-Planetary Mill PULVERISETTE 4 classic line, you require at least 2 grinding bowls of your choice and the corresponding number of grinding balls. The grinding bowl material must also be harder than the material to be ground. In normal cases, grinding bowls and balls of the same material are used. To shorten the grinding time, grinding bowls and balls with a higher density and correspondingly higher impact energy can be used. Please take note of the useful capacity, this is not identical with the bowl volume!

For the Planetary Mill PULVERISETTE 5/4 classic line, you require at least 4 grinding bowls of your choice and the corresponding number of grinding balls. The grinding bowl material must also be harder than the material to be ground. In normal cases, grinding bowls and balls of the same material are used. To shorten the grinding time, larger or heavier grinding bowls and grinding balls with a higher density and correspondingly higher impact energy can be used. Please take note of the useful capacity, this is not identical with the bowl volume!

 

For achieving best grinding results grinding balls are available in 0.1 - 15 mm/20 mm/40 mm diameters and in 7 different materials, thus directly preventing contamination of the samples as a result of undesired abrasion. The recommended number of balls per grinding bowl can be found in the selection aid.

 

For the Mini-Mill you require 1 grinding bowl and the corresponding number of grinding balls. To avoid undesired contamination of the sample through abrasion, we offer a selection of 4 different material types. Normally, grinding bowls and balls of the same material are used. In principle, the grinding bowl material must be harder than the material to be ground. 
Grinding bowls and grinding balls made of zirconium oxide for absolute metal-free grinding are also offered. Important: please keep in mind the specified useful capacity as this is not identical to the bowl volume.

For achieving best grinding result grinding balls are available in ≤ 3 mm - 15 mm diameters and in 4 different materials, thus directly preventing contamination of the samples as a result of undesired abrasion. The 5 ml PTFE bowl is especially suited for biotechnology applications. The recommended number of balls per grinding bowl can be found in the selection aid.
It may also be useful to work with grinding balls ≤ 3 mm diameter. We have not listed these here because we would like to advise you personally regarding this application. Please contact Leos Benesour laboratory manager.

 

General material specification:
Material: zirconium oxide - ZrO2
Abrasion resistance: very good
Suitable for: fibrous, abrasive samples

 

100 grinding balls made of zirconium oxide with 5 mm dia. weigh approx. 38 g. With the weight information, the high number of balls per grinding bowl can be determined by weighing.

Grinding balls with diameter 3 mm and smaller must be weighed out. The above table provides you with the necessary weight to be included per grinding bowl.

The quantity of grinding balls can be reduced by up to 15 %; however, increased wear can then be expected. The specified number/mass of balls per bowl is the minimum quantity; depending on the material behaviour, it may be necessary to increase this.

In normal cases, grinding bowls and balls of the same material are used. To shorten the grinding time, grinding bowls and balls with a higher density and correspondingly higher impact energy can be used.
