Sonication is the act of applying sound energy to agitate particles in a sample, for various purposes such as the extraction of multiple compounds from plants, microalgae and seaweeds. Ultrasonic frequencies (>20 kHz) are usually used, leading to the process also being known as ultrasonication or ultra-sonication.. In the laboratory, it is usually applied using an ultrasonic bath or an .
Laboratory hot plates present obvious dangers, such as the potential for people to burn themselves or even start a fire. While newer hot plates are manufactured to avoid sparks, older hot plates are more of a spark risk due to the position of the "on-off" switch on the unit itself as well as the bimetallic thermostat, which can become corroded.
This cut water use 80 percent, saving the laboratory 24.8 million gallons of water and 235,000 annually. 5. Use Water-Smart Landscaping and Irrigation. Planting native and drought-tolerant plant species minimizes the need for supplemental irrigation. Landscape water use can also be reduced 10 to 20 percent by having an irrigation water audit.
Jun 23, 2019 · Hotplates are perhaps the most versatile heat source in the laboratory and can be used to heat beakers, Erlenmeyer flasks, and various hot baths (water, sand, and oil baths).
