Vibratory Micro Mill
PULVERISETTE 0
Please note: For the FRITSCH Vibratory Micro Mill PULVERISETTE 0 you require a mortar, which must be equipped with a grinding ball. The mortar material must always be harder than the material to be ground. Generally mortars and grinding balls of the same material are used. All FRITSCH mortars are rimmed, regardless of the material, in a robust shell of shock-resistant aluminum, which protects the actual mortar. For fast embrittlement of soft, slightly oily, fatty or moist materials for cryogenic grinding, we offer the FRITSCH cryo-box.
For grinding and sieving in one unit convert the PULVERISETTE 0 into the
Vibratory Sieve Shaker ANALYSETTE 3 SPARTAN

SPECIAL ACCESSORIES
For cryogenic grinding: the perfect fast embrittlement of soft, slightly oily, fatty or moist materials, we offer the FRITSCH cryo-box: Simply insert the filled grinding set into the cryo-box and fill it with liquid nitrogen with this method even extremely difficult-to-grind samples can be ground down to analysis fineness. And the thick insulation ensures a particularly efficient use of coolant
Clamping lids for dry and wet sieving are also available.
To reduce the grinding sound we recommend a sound absorption hood.
ACCESSORIES FOR CRYOGENIC GRINDING
Device for grinding in liquid nitrogen.
The grinding set is placed in a cryo-box to grind soft, oily, fatty or moist materials by adding liquid nitrogen to embrittle the grinding material. This method is used to reduce samples which are very difficult to grind (e. g. slivers of soft PVC) to analytical fineness. The thick insulation of the cryo-box keeps coolant costs low.
For cryogenic grinding, a mortar and a grinding ball made of stainless steel, tempered steel or hard metal tungsten carbide should be used.
Please note: Grinding sets made of agate and sintered corundum cannot be used in the cryo-box.
SOUND ABSORPTION HOOD
To reduce the grinding sound, we recommend the sound absorption hood made of plexiglas.
CLAMPING LIDS
For dry sieving with test sieves 200 mm/8" dia.
The clamping lid made of plexiglas allows the operator to observe the sieving process.
For applications, where it is not required to observe the sieving process, a clamping lid without window insert article no. 31.2050.00, is also available.
This clamping lid can also be used if you would like to use the Vibratory Micro Mill PULVERISETTE 0 as a Vibratory Sieve Shaker ANALYSETTE 3 SPARTAN. The needed sieve pan and the sieves must be ordered separately.
For dry sieving for all test sieves up to 200 mm/8" dia.
The POM plastic clamping lid without window for applications, where it is not required to observe the sieving process, respectively in order to sieve materials where a metallic contamination must be avoided. For applications, where it is required to observe the sieving process, a clamping lid with window insert article no. 31.2020.00, is also available.
This clamping lid can also be used if you would like to use the Vibratory Micro Mill PULVERISETTE 0 as a Vibratory Sieve Shaker ANALYSETTE 3 SPARTAN.
The needed sieve pan and the sieves must be ordered separately.

With 2 rotation nozzles for wet sieving with test sieves 200 mm/8" dia.
The wet clamping lid features 2 rotation nozzles which sprays the entire interior chamber, thus helping to flush the material through the sieve apertures.
Especially recommended for materials with a high electrostatic charge or very high content of fine material. This clamping lid can also be used if you would like to use the Vibratory Micro Mill PULVERISETTE 0 as a Vibratory Sieve Shaker ANALYSETTE 3 SPARTAN. The needed sieve pan and the sieves must be ordered separately.
Certification
IQ/OQ documentation (questionnaire format - implementation by customer) for the independent support of instrument qualification in the quality management system for the Vibratory Micro Mill PULVERISETTE 0.
