Help with Laboratory Homogenizers specifications:
Media Type
Back to Top
|
|
| ||
| Media Type: | Other media characteristics, such as pH, concentration, and specific gravity, are important and should be discussed with the vendor for compatibility. | ||
| Your choices are... | |||
| Liquids, Solutions, Emulsions | Mixers and Homogenizers used for mixing combinations of liquids, solutions and emulsions. Solutions consist of a substance (called a solute) dissolved in a liquid (called a solvent). Emulsions are combinations of immiscible (unblendable) liquids, such as oil and water. | ||
| Suspensions, Slurries, Pastes, Colloids | Mixers and Homogenizers process liquids containing solids. Suspensions (including slurries and pastes) are liquids that contain solid particles sufficiently large for sedimentation. Colloids have smaller particles that will not settle. | ||
| Powders or Granules | Devices process powder or granular materials, such as dry cement. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| Media Viscosity | Viscosity is a measure of a fluid's thickness. Thicker materials require more energy for mixing, homogenizing, or blending. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
Operating Capacity

|
|
| ||
| Capacity | Capacity is the volume of product that a device can accommodate. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
Operating Configuration

|
|
| ||
| Mixer Type: | |||
| Your choices are... | |||
| Fluidized Bed | Fluidized bed mixers fluidize the complete product bed and are very efficient and thorough, as indicated by higher applied horsepower, rotational speeds and more durable vessel construction. | ||
| Rotor-Stator | Rotor-stators are single-shaft mixers with an impeller rotating in close proximity to a stationary housing. They are used to rapidly break apart solid particles in a liquid, and for emulsification. The impeller or rotor mechanically imparts high shear forces to the ingredients. Clumps of particles are also broken apart by the hydraulic shearing forces generated as particles are ejected through openings in the stator into the rest of the batch. Rotor-stators are particularly effective at chopping coarse particles such as rubber or flake resin. The stator directs the flow and confines the particles. The rotor imparts shear. | ||
| Ultrasonic / Vibrational | Ultrasonic mixers or vibrational mixers apply ultrasonic waves to a mixed medium to produce a steep gradient of acoustical pressure which moves the fluid and provides a very fine level of mixing action. | ||
| Other Mixer Type | Other unlisted, specialized or proprietary mixers, homogenizers, and blenders. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| Mounting | |||
| Your choices are... | |||
| Handheld | Handheld units are typically smaller-scale mixers or homogenizers that are often used in laboratory settings. | ||
| Portable | Portable mixers are smaller mixers (5 hp or less), some of which are portable enough to be moved from tank to tank. Truly portable mixers are normally clamped at an angle to the top edge of the tank or an adjacent support. | ||
| Benchtop | The homogenizer is a permanent, benchtop instrument. | ||
| Stand Mounted | The homogenizer is mounted on a stand, and may be removed for manual use. | ||
| Overhead | Overhead mixers are mounted above the mix tank and inserted into the fluid. The vertical position can be adjusted to accommodate the quantity of fluid and fluid viscosity. | ||
| Floor-Mounted | Floor-mounted mixers and homogenizers are large-scale systems that are permanently installed as part of a manufacturing process. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
Mix Rate / Motor Speed

|
|
| ||
| Motor Speed | Motor speed is the speed range of the mixer. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| Motor Power | Motor power is the power range of the motor. | ||

Optional Features / Capabilities
Back to Top
|
|
| ||
| Additional Features | |||
| Your choices are... | |||
| Cooling | The mixer has an internal cooling element. | ||
| Heating | The mixer has an internal heating element. | ||
| Mag Drive | A magnetic mixer is ideally suited for continuous stirred reactors (CSTR), and batch reactors where mixing and agitation must be contamination-free and leakage cannot be tolerated. The magnetic drive eliminates seals, and also the problems associated with rotating seals, such as leakage, contamination, and constant maintenance. | ||
| Lined or Coated | The interior surface of the mixer is lined or coated to provide a non-stick, chemically resistant interior, especially desirable for acidic processes, high-purity chemicals, pharmaceuticals, certain polymers and other multi-use applications. | ||
| Timer | The mixer has a timer for timed runs. | ||
| Programmable | Products are programmable or adjustable to provide for different ranges, materials, levels, outputs, etc. | ||
| Explosion Proof | The mixer has an explosion-proof housing or intrinsically-safe wiring to prevent an explosion during use. | ||
| Interchangeable Rotors | The homogenizer uses interchangeable rotors to accommodate different types of samples. | ||
| Disposable Rotor | The rotor can be thrown away after one or multiple uses. | ||
