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.

Grainger Magnetic Retrieval Tool Cushioned 29
The Grainger 16W186 is a compact fluorescent light bulb that provides 800 lumens of light output. This 13 watt bulb has a medium screw base and is designed to replace a 60 watt incandescent bulb. With an estimated life of 10,000 hours, this CFL bulb has an A19 shape and emits a soft white 2700K light. The bulb has an energy star certification for efficiency. This is a good option for energy savings in table lamps, floor lamps and other general purpose lighting fixtures that accept medium base bulbs.
Grainger Back Chamfering Tool
The Micro 100 Back Chamfering Tool is a carbide insert tool designed for back chamfering and deburring. It has a 45 degree entering angle and features replaceable carbide inserts with four cutting edges. The tool body is made from tool steel and accepts inserts with a .250" IC size. It is available in shank diameters ranging from 1/4" to 1/2", and overall lengths from 2" to 4". The chamfering tool can be used on most materials including steel, stainless steel, cast iron, aluminum, brass, bronze, plastics and composites. It provides an economical way to deburr holes and add a precision chamfer.
