5 Key Points to Selecting the Correct Ultrasonic Cleaner Size
Ultrasonic parts cleaners are manufactured in a tremendous variety of sizes. By “size” we mean the dimensions and capacities of tanks in which ultrasonic parts cleaning is accomplished. For example the Elmasonic E Plus series is offered in 9 tank capacities from 0.25 to 7.5 gallons and the Select Series in 11 capacities from 0.7 to 23 gallons. Industrial-sized units such as SHIRACLEAN can hold 100 gallons or more. This post will help you select the correct ultrasonic parts cleaner size.
Five Points to Selecting your Ultrasonic Parts Cleaner Size
Here are the key points to consider:
- Parts you are cleaning
- Cleaning tank dimensions
- The importance of “working depth”
- The role of cleaning baskets
- Cleaning solution volume and service volume
1. What Parts are you Cleaning?
Ultrasonic parts cleaning has proved a very effective and economical way to remove all types of contaminants from nearly anything that can be safely … Read the rest
Explosion Proof Ultrasonic Cleaner Options
Explosion-proof ultrasonic cleaners must be used when cleaning tasks call for the use of volatile solvents to achieve the desired results. See examples below. When low flash point flammable solvents are involved in an ultrasonic cleaning operation, a number of precautions are called for in addition to using an explosion-proof ultrasonic cleaner. This is because using these solvents creates what the NEC and NFPA term a hazardous location.
A flash point is the temperature at which a particular organic compound gives off sufficient vapor to ignite in air when given an ignition source. In view of this, selection of an ultrasonic cleaner must take into account that not only do volatile solvents evaporate, but the heat generated by the ultrasonic cleaning process accelerates solvent evaporation and vapor generation.… Read the rest
Powerful Lab Sonicator Speeds Sample Prep in Pharma Research
Ultrasonic cavitation is often employed for sample preparation in pharmaceutical labs. High ultrasonic power density is ideal for these applications because it accomplishes the job quickly. This minimizes cavitation induced heat buildup that can cause chemical degradation of samples.
Sample prep is generally accomplished by suspending sample flasks in ultrasonic cleaners containing water and a surfactant. Cavitation generated by ultrasonic transducers passes through the flask walls to act on the sample.
Most equipment used in this application handles several flasks at once for production-scale operations. An alternative design has proved especially efficient by speeding up the sample prep process in pharmaceutical research laboratories. The secret is in the design.
