B.Braun Mikro Dismembrator U Vibration Laboratory Ball Mill for Sample Homogenization

The B.Braun Mikro Dismembrator U is a precision vibration grinding mill designed for efficient and reproducible fine grinding, homogenizing, and mixing of small sample volumes typically required in molecular biology, biotechnology, and clinical diagnostics. Featuring an adjustable shaking frequency from 50 to 2000 rpm and a 16 mm shaking amplitude, it supports both dry and wet milling protocols, including the treatment of frozen samples essential for maintaining biomolecular integrity.

Key technical specifications:

• Shaking frequency: 50–2000/min, suitable for controlled disruption of biological tissues and inorganic materials
• Shaking amplitude: 16 mm for effective particle size reduction reaching final fineness of ~1 µm
• Digital display for precise time adjustment up to 98 minutes enables reproducible processing and protocol adherence
• Compact dimensions: 300 x 250 x 200 mm and a weight of 19 kg, providing bench-top feasibility in laboratory environments
• Mixing bowls (grinding jars) are sold separately, allowing customization based on sample type and processing needs

This equipment is widely used in biotechnology research fields such as gene editing workflows, synthetic biology, and bioprocessing, where sample homogenization and particle size reduction are critical. It is essential for preparing contamination-free samples for trace element analysis, nucleic acid and protein isolation, and other molecular diagnostics applications. Its versatility in handling organic and inorganic materials makes it valuable across biomedical engineering and clinical research sectors.
