fritsch Ball Millsare the most effective laboratory mills for rapid batchwisecomminution of medium-hard to hard samples down tothe fi nest particle size. The grinding can take place dryor wet. Grinding sets of many different materials areavailable. fritsch Ball Mills are also the ideal andreliable lab assistants for mixing and homogenising.Mini-MillPULVErisEttE 23Vibratory Micro MillPULVErisEttE 0the smallest instrumentfor small quantitiesfine comminution andsieving in one unitOperating principle Impact force Impact forceOptimal for material typeMedium-hard, brittle, moistMedium-hard, brittle,temperature-sensitive, moistGrinding bowl sizes 5, 10, 15 ml –Grinding ball diameter 0.5 – 15 mm 50 – 70 mmMax. feed size (depending on the material) 6 mm 5 mmMin. sample quantity 1 ml 1 mlMax. sample quantity 5 ml 10 mlfinal fineness (depending on the material) 5 µm 10 µmtypical grinding time (depending on the material) 2 min 10 mincryogenic grindingLiquid nitrogen can be used forpre-cooling in the PTFE bowlYesGrinding process Dry/wet Dry/wetGrinding bowl oscillations per minute 900 – 3000 at 9 mm amplitude 3000 – 3600 at 1 – 3 mm amplitudeElectrical details 100-240 V/1~, 50-60 Hz, 90 watt 100-240 V/1~, 50-60 Hz, 50 wattWeight Net: 7 kg, gross: 8 kg Net: 21 kg, gross: 22 kgDimensions w x d x h Bench top instrument: 20 x 30 x 30 cm Bench top instrument: 37 x 40 x 20 cmPacking details Cardboard box: 37 x 25 x 34 cm Cardboard box: 50 x 43 x 30 cmGrinding in a Ball Mill takes place through impact andfriction of the sample between the grinding balls and theinside wall of the grinding bowl respectively the mortar.For this, the grinding bowl or mortar performs verticallyoscillating movements of high amplitude and high frequency,which are transferred to the grinding vessel.3

Your advantage: Unmatched grindingperformance with a signifi cantly improved grinding effect,much easier recovery and simpler cleaning.Typical FRITSCH!The 5 ml PTFE bowl is specially suited for using the FRITSCHPULVERISETTE 23 in biotechnology applications. Forexample, it is possible to break up fungus or yeast cells,deep frozen tissue and cells in only a few minutes withthis special plastic bowl and a 10 mm steel ball. It is alsopossible to pre-cool the entire bowl in liquid nitrogen.Especially practical: The spherical grinding bowls of thePULVERISETTE 23 are assembled simply and quickly, justtwist and turn!4

To avoid undesired contamination of the sample through abrasion, we offer a selection of 5 different materialtypes. Normally, grinding bowls and balls of the same material are used. In principle, the grinding bowl material must beharder than the material to be ground.

P U L V E R I S E T T E 0M O R T A R A N D G R I N D I N G B A L L SFor the FRITSCH Vibratory Micro Mill PULVERISETTE 0, you require a mortar, which must be equipped with a grinding ball. Tooptimally adapt the grinding to any sample type, you can choose between 6 different materials, whereby mortars and grindingballs of the same material are generally used. Important: The mortar material must always be harder than the material tobe ground. For cryogenic grinding, use mortars and grinding balls made of steel or tungsten carbide. The PULVERISETTE 0can also be converted to a Vibratory Sieve Shaker ANALYSETTE 3 SPARTAN for dry and wet sieving.
