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 Back Chamfering Tool
The Micro 100 Indexable Chamfering Tool is a high-performance chamfering tool designed for chamfering, facing, and grooving operations. It features a carbide insert with six cutting edges for extended tool life. The tool has a shank diameter of 3/4 inches and an overall length of 4 inches. It can machine a variety of materials including steel, stainless steel, cast iron, aluminum, and more. The chamfering tool provides excellent chip control and consistent chamfer quality in one pass. It is ideal for chamfering holes, slots, keyways, and more in machining applications. The tool requires a holder for mounting and comes with assembled screws for easy insert changes.
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.
Alabama Research And Development Alabama Research and Development,10MM Tissue Coring Tool
Alabama Research and Development has developed new improved coring tools for cutting cylindrical live tissue cores for use in the Alabama R&D Tissue Slicer. Thin wall stainless steel tubing used in other coring tools does not hold an edge well and is difficult to sharpen. The new coring tools are made from heat-treated, knife-quality stainless steel. The cutting edge angles are designed to give sharp, well-formed tissue cores which is important for use in the Alabama R&D Tissue Slicer. With proper handling, the coring tools should more than triple the life of the older tools.The tools can be used either as hand-held tools or with the Alabama Research and Development tissue coring press. The coring tools are available in four sizes.
MSC Bosch Power Tool Hose Adapter, Composite, Quick Click System, Air Regulating Slider
The Power Tool Hose Adapter is designed for efficient dust extraction, connecting to various tools and attachments. It features a rubber-nozzle tool end for a secure friction fit and an air regulating slider to control airflow, which is particularly beneficial for applications like sanding where reduced airflow prevents the tool from sticking to the workpiece. Its quick click feature ensures a secure attachment to the hose, and the nozzle is designed for a comfortable grip.
- Connects to hose with the quick click system.
- Rubber nozzle sized for a friction fit on most dust collection attachments.
- Air regulating slider controls the amount of air flow.
- Prevents tool from sticking to the workpiece during sanding by reducing airflow.
- Quick click feature for secure attachment.
- Nozzle designed for a comfortable grip.
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.
