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.

Kinematica™ Polytron™ PT-DA 30/2MEC-F250 Generator
Outside blades pre-cut samples that are larger than the rotors diameter. Subsequently, they can be dispersed inside the generator.
Kinematica™ POLYTRON™ PT 1300D Stand
Stainless steel hinge stand with gas spring and base mounting support. The drive support can be rotated in any direction. It can be raised or lowered.
Kinematica™ Polytron™ 10-35GT, 3100D, 45-80GT & 6100D Generator/Probes
Polytron™ dispersing aggregates are available in different designs, like rotor with knives for pre-cutting, rotor/stator with several teeth rows for fine or double emulsions, mechanical seals for vacuum and pressure applications, and more.
Kinematica™ Polytron™ 20 mm generator, PT-DA 20 / 2WMEC-E192
The W-design prevents fibrous, stringy or solid samples from clogging the aggregate. W-design aggregate with knives.
Kinematica™ Polytron™ 2500E Generator/Probes
The most diverse generators on the market, the POLYTRON™ dispersing aggregates are solution driven, designed specifically with the customer's adaptive markets in mind. Polytron aggregates vary in design, for process and sample purposes, and shaft length, for differing mixing vessel purposes.
Cole-Parmer™ Grinding Vials, Polystyrene with Slip-On Polyethylene Cap
2.5 mL polystyrene grinding vial that includes a slip-on polyethylene cap.
Ops Diagnostics 100 micron Zirconium Beads, 1200 mg Pre-Filled Tubes (100 count)
Tougher than silica, less expensive than stainless steel, and inert in most solutions, 100 µm Acid Washed Zirconium Beads are suitable for homogenizing bacteria and small tissues. May also be used as a sonication additive.Beads are available in Acid Washed, Low Binding, and and Molecular Biology Grade format. Since untreated beads are notorious for containing large amounts of debris and dust, all beads are acid washed, at a minimum, prior to packaging. Low Binding Beads are chemically altered using a proprietary process to bind less biomolecules liberated from homogenized samples. Pre-Filled Tubes are a convenient solution for labs seeking time savings by no longer requiring researchers to weigh, fill and QC individual tubes. They are available in 2 mL skirted (i.e., self-standing) or unskirted polypropylene tubes to ensure compatibility with most tube homogenizers. Clear screw caps with O-rings included.
