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.

It provides an economical way to deburr holes and add a precision chamfer.
Grainger Tool Safety Cover 14x5x14 In Clear
The HUOT Tool Safety Cover is a durable plastic cover designed to protect tools and equipment. It measures 12 inches wide x 18 inches long x 6 inches high and features a hinged lid for easy access. The cover is made from high-density polyethylene plastic to withstand impacts and has ventilation holes to allow airflow. It can accommodate most hand tools up to 12 inches long. The HUOT safety cover comes in orange for high visibility and has a latch to securely close the lid. This tool box helps organize, transport, and protect shop tools and power tool accessories.
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.
