Homogenizers and Immersion Blenders
Devices designed for overhead immersion into substances; ideal for pulverization of plant/animal tissue, grain/seed, sample prep, and more. Includes accessories such as generator probes of varying tips, stand assemblies, bead mill tubes, and more.
Homogenizers can be used with tissue, plant, food, soil, and other sample types. Homogenization is a common sample preparation step for analyzing nucleic acids, proteins, cells, metabolism, pathogens, and other targets.
Cell fractionation releases the contents of cells, and newer methods have been designed to consider quality and environmental aspects, cross-contamination, aerosol generations, infection risk, and noise levels. Different methods have been developed for disrupting cell walls and other structures. These include bead mills, sonication, rotor-stator mechanical, high pressure, and other physical methods.
For biological work, sonication may adequately disrupt or deactivate biological material via the process of sonoporation. Sonic dismembrators can break up cells and fragment DNA molecules by subjecting the sample to ultrasonic waves that create small fragments.
Some substances can be mechanically homogenized using beads and other small pieces of metal or minerals. The sample is added to a vial that contains these small particles; the tubes are then rapidly agitated, which breaks down the materials. Depending on the equipment, many samples can be processed simultaneously with this method.
Another mechanical homogenization method is the rotor-stator; these devices have a fast-spinning inner rotor and a stationary outer sheath (stator). Samples are subjected to tearing, shear fluid forces, and cavitation (bubble formation and collapse). A rotor-stator processes a single sample at a time; high-throughput and continuous use models are available.
An immersion blender has an electric motor that powers rotating blades at the end of a shaft. The device is lowered into the sample or mixture and the motor activated. The device may be hand-held or clamped to a stand.
Homogenizer packages are also available for motorized methods.

Electron Microscopy Sciences BeadBug™ Microtube Homogenizer, 230V, EU Plug
The BeadBug sets the performance standard for personal sized cell disruption and lysis instruments. Developed for samples too tough to be homogenized in a common lab vortexer, the BeadBug provides a convenient and economical alternative to the traditional, over-priced homogenizers.
With a foot print of just 7 x 8" and a capacity of up to three tubes, the BeadBug is the ideal homogenizing instrument for low to medium throughput laboratories.
Simultaneous homogenization takes place (often within 45 seconds) of up to 3 samples inside the disposable 2 ml screw cap microtubes. The optimized mixing motion causes rapid cell disruption through constant high velocity impact from the hardened micro-beads chosen specifically for your sample type.
Thomas Scientific Tubes (empty) pack of 1000 with caps and sealing ring
Supplied in bulk or in 2.0mL tubes-prefilled with beads Compatible with all common bead homogenizers Available in glass, ceramic or stainless steel Unique Triple-Pure™ grade: Acid washed, heat treated and tested free of nuclease Bead beating is quickly becoming the preferred process used to break up (lyse) samples in order to release the DNA, RNA and proteins contained within cells. Samples are placed in tubes with the appropriate grinding beads and subjected to high energy mixing. The beads impact the sample, eventually breaking it down on the cellular level releasing subcellular contents. A variety of prefilled tubes are available for homogenizing samples including those with stainless steel, glass and Triple-Pure™ zirconium beads. All three bead types are acid washed and processed to remove nucleases and proteases. The Triple-Pure bead tubes undergo special handling during filling and are quality tested to ensure the elimination of DNase, RNase, protease, and nucleic aci
