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.

Cole-Parmer IKA 3720001 T-18 Ultra Turrax Digital Homogenizer; 115 VAC
The 500-Watt motor offers stable operation in a variety of media samples, and variable speed control from 500 to 25,000 rpm. Stainless steel dispersion elements remove quickly and clean completely for reuse. The digital unit features electronic speed control and overload protection. The rotor-stator generator uses a pump-like action to constantly draw in sample. Through a combination of shear, impact, collision, and cavitation, the generator rapidly disperses and disintegrates the material suspended in the media. Easily detached rotor-stator generators makes the exchange and use of two dispersing elements seamless. Clamp sold separately.
Sigma Aldrich Fine Chemicals Biosciences Micro emulsifying needle w
Widely used for allergens and the mixing of adjuvants and antigens oil based liquids or any two liquid media differing in viscosity. By locking two syringes on to the double hub needle or double hub adapter two liquids such as a mineral oil and an emulsifying agent may be readily pumped between the two syringes to produce a uniform mixture. Indicated lengths are the overall length. Researchers and technicians utilize Micro-Mate(R) 5 mL and 10 mL Luer lock tip glass syringes for micro-emulsifying procedures. The outstanding quality of the glass and the special secure Luer locking tip provide quality and reliability.
