Ultrasonic Processors UP-250 is a multi-functional and multi-purpose instrument that uses ultrasonic waves to produce cavitation effects in liquids; it can be used to break a variety of animals, plants, viruses, cells, and bacteria, and can be used for emulsification, Dispersion, homogenization, extraction, defoaming, cleaning, preparation of nanomaterials, dispersion and acceleration of chemical reactions, etc.

◆Used for crushing animal and plant cells, bacteria, spores or tissues, extracting protein from cells and conducting scientific culture experiments of viruses and vaccines.
◆Accelerate the reaction speed of chemistry and physics and accelerate the degassing of liquid.
◆Scientific analysis of crude oil dilution, oil-water emulsification, accelerated decrystallization, and glass homogenization.
◆Disperse rare earths, various inorganic minerals, and prepare a homogenized mixture of nearly one percent of nanometer latex, etc.
◆Quick, powerful and high-precision lotion for mold micro-holes and blind holes.

Experiment purpose
1. Understand the basic principles of ultrasonic cell disruption
2. Master the basic technology of ultrasonic cell disruption

Experimental principle
When the strong sound wave acts on the solution, the bubble generation, growth and breaking are related to the cavitation phenomenon. The shock wave and the scissors force caused by the cavitation phenomenon cause the cells to lyse.

Materials and reagents
Bacteria 10ml, beaker, shaved ice, 75% alcohol cotton ball.
