P-0

The P-0 vibratory micro mill offers laboratories a versatile solution for the fine grinding of medium-hard, brittle, moist or temperature-sensitive samples with the smallest sample volumes of 1-10 ml. With an achievable final fineness of up to 5 µm, the device is particularly suitable for loss- and agglomeration-free grinding in areas such as chemistry, biology, the environment, pharmaceuticals and materials research.

Optimum sample preparation for RoHS tests

The P-0 vibratory micro mill is especially recommended for sample preparation for RoHS (Restriction of Hazardous Substances) tests. When analyzing electronic components for prohibited substances such as lead, mercury, cadmium or hexavalent chromium, loss- and agglomeration-free grinding is crucial for reliable measurement results. The vibratory micro mill enables the precise preparation of printed circuit boards, plastic parts, housings and cables for subsequent spectroscopic analyses. Unwanted contamination can be avoided by selecting different grinding bowl materials.

Unique functionality for cryogenic grinding

The P-0 vibratory micro mill is currently the only vibratory ball mill on the market that can be used to cryogenically grind viscoplastic materials in direct contact with nitrogen. The optionally available cryo-box enables the rapid embrittlement of soft, slightly greasy or moist materials. By simply inserting the filled grinding set and filling it with liquid nitrogen, even samples that are extremely difficult to grind are easily reduced to analysis fineness. The strong insulation ensures particularly economical coolant consumption.

Grinding and sieving in one device

The device combines fine grinding and sieving functions: by simply inserting the appropriate sieves, the P-0 vibrating micro mill can be converted into a vibrating sieve shaker for quantitative particle size analysis - for both dry and wet sieving. The measuring range covers 32-63 µm for solids and 20 µm-10 mm for suspensions.

Precise adaptation to every sample

Comminution is achieved by impact and friction by electromagnetically vibrating the mortar. The oscillation amplitude is freely adjustable and can be precisely adapted to the sample to be ground. At 3,000-3,600 vibrations per minute with an amplitude of 1-3 mm, the coarse particles are first crushed by the impact of the grinding ball. The fines are then crushed by the tumbling motion of the grinding ball as the oscillation fades out due to friction. This two-stage grinding avoids agglomeration phenomena and ensures reproducible results.

Versatile material options and applications

Five different materials for mortars and grinding balls are available for optimum adaptation to each sample type. All mortars are encased in a robust aluminum shell that protects the mortar itself. In addition to RoHS analysis, the mill is also suitable for the rapid homogeneous production of emulsions and pastes.

With a compact design of 37 × 40 × 20 cm, a weight of 21 kg and a low energy requirement of 50 watts (100-240 V/1~, 50-60 Hz), the device can be used flexibly in the laboratory. The ergonomically positioned membrane keypad is splash-proof (IP65), a window allows the grinding progress to be monitored and a digital timer ensures reproducible results.
