Mixer Mill MM 500 Vario

Processing 2 to 50 samples in one batch

The new Mixer Mill MM 500 vario is a versatile bench-top unit which provides ultimate performance with maximum flexibility for your sample preparation process.

It is used for dry, wet and cryogenic grinding of small sample amounts with high throughput. The MM 500 vario can be equipped with screw-top grinding jars from 1.5 ml to 50 ml. Available materials include hardened steel, stainless steel, tungsten carbide, agate, zirconium oxide, PTFE.

For biological applications such as homogenization of plant materials, tissues or for cell disruption via bead beating, the MM 500 vario can be equipped with different adapters for single-use vials from 0.2 - 5 ml.

• Powerful pulverization with up to 35 Hz
• Twice as fast as mills with only 30 Hz
• Ergonomic design with touch display

Flexibility

• Suitable for dry, wet or cryogenic grinding
• Equally suited for rapid (<2 min) and long-term grinding (up to 99 hours)
• 12 SOPs and 4 program cycles with max. 99 repeats facilitate routine applications
• Grinding jars of various sizes and materials; adapters for single-use vials 

Solutions for biological applications and cell disruption

Mixer mills are widely used for homogenizing biological samples such as tissue, liver, muscle, plants, corn or sputum. For cell disruption via bead beating mixer mills are also the perfect solution. The MM 500 vario accommodates adapters for different single-use vials:

0.2 ml / 1.5 ml / 2 ml / 5 ml

Depending on the tube and the type of adapter, 5-10 tubes can be inserted per adapter, resulting in the following maximum vial capacity per batch:

50 x 1.5 or 2 ml (or 60 x 0.2 ml)

20 x 5 ml

Typical grinding / homogenizing processes of biological materials take less than 2 min. Cell disruption with a good reproducibility and efficiency takes 20 sec to 5 min, depending on the cell type. Cryogenic grinding in single-use vials can also be a suitable way to pulverize tough or temperature-sensitive samples.
