微型珠磨式研磨器

The micro-MiniBeadbeater is an entry-level, small sample cell disrupter. Samples are processed one vial at a time. Disruption performance is comparable to other MBB models. For applications requiring a selection of shaking speeds, see the MiniBeadbeater-1. For processing more than one sample at a time, see MBB-8, MBB-16 and MBB-96.

Up to 300 mg of cells or tissue are sealed inside a special screw-cap microvial (see below) that also contains 0.1 - 1.5 ml of extraction solution and tiny ceramic or steel beads. The vial contents are violently agitated inside the micro-MiniBeadbeater. Spores, resistant yeast, and fresh or frozen fibrous tissues from plants or animals can be completely homogenized in 1-3 minutes of operation.

 

This non-foaming, non-aerosol method is the method of choice for isolating enzymes, nucleic acids and organelles from small samples. It is commonly used with PAGE, polymerase applications and diagnosis using antibody or oligonucleotide probes. High yields of intact DNA or RNA are obtained by simultaneous disruption and extraction in phenol, guanidinium-SCN solution, or a commercial kit reagent. Sterile techniques are easily accommodated to recover viable intracellular virus and bacteria from plant and animal cells.  Because the beads and vials are disposable, there is absolutely zero cross-contamination between samples - an essential feature for PCR techniques.

 

The microMiniBeadbeater also is used for dry grinding.  Here, steel beads are added to hard samples such as bone, teeth, seeds and minerals and are completely powdered in 10-60 seconds.  Softer materials such as biological tissue, rubber or plastics are powdered by pre-chilling the sample to liqN2 temperatures first.

* This product uses special 1.5 ml vials.  See below for details.
