The Mini-Beadbeater-16 is a high-energy cell disrupter designed to handle four to sixteen samples at a time.

The Mini-Beadbeater-Plus™ is an upgraded version of the venerable Mini-BeadBeater-1.  Improvements include a programmable timer, a powerful brushless motor and 115/230 VAC compatibility. The high-energy bead-mill rapidly and completely disrupts microorganisms and plant and animal tissue.

The SoniBeast™ is our newest addition to our stable of high energy BeadBeater cell disruptors. Small samples of tissue or cells are completely disrupted in seconds rather than minutes. It processes up to twelve 0.6 ml locking-cap PCR microtubes, each containing 1-100 mg of sample, or three 2 ml microvials each containing 10-400 mg sample. The SoniBeast is designed for wet milling in water-based media. Common applications are…

The NEW SpiralPestle™ and 1.5 ml Microtube grinder is an significant improvement over traditional smooth-walled polypropylene pestle and tube combinations.  It is used to homogenize culture cells and small samples (<100 mg wet weight) of soft tissue such as liver, brain, and muscle.  It can also be used to disperse centrifugal pellets, precipitates, and other solids.

The Tissue-Tearor is a rotor/stator type tissue homogenizer which can rapidly homogenize, disrupt, and emulsify samples in 0.5 - 1000 ml of liquid. Complete homogenization of tissues (muscle, liver, breast tissue, etc.) is usually achieved in ten to thirty seconds. Little, if any, heat is produced during the process.

The BioPulverizer quickly fragments hard frozen tissue samples into tiny pieces the size of grains of sand or course powder. The primary benefit of pulverizing pieces of tissue is to optimize subsequent rapid and complete cell lysis using lytic solutions or mechanical homogenizers. For difficult tissues such as tendon, skin, and tumors it is an essential step (read more). The BioPulverizer is also used at room temperature to…
