Using an Ultrasonic Cleaner in the Animal Hospital
Veterinary surgeons in animal hospitals and veterinary clinics will quickly see the benefits of using an ultrasonic cleaner to thoroughly remove blood and tissue from veterinary equipment such as knives, probes, curettes, trimmers and pipettes. The ultrasonic cleaning process is fast and much safer than hand scrubbing surgical instruments because it reduces the potential risk of staff injury and damage to sharp edges.
How it Works
An ultrasonic cleaner operates on the principal of cavitation – the action of billions of minute bubbles imploding on the surface of objects immersed in the ultrasonic cleaning solution. These bubbles are created by generator-powered ultrasonic transducers mounted on the cleaner’s tank and can reach the tiniest cracks, crevices and blind holes in the instruments to blast away contaminants without damaging delicate surfaces.… Read the rest

Ultrasonic Cleaning Options for Plastic Injection Molds
Injection-molded plastic parts are everywhere a part of our daily life. Polymers in a variety of formulations are used to produce these components by being injected into intricately designed molds and subjected to heat and pressure. Because molds represent substantial investments they must be cleaned on a regular basis. Ultrasonic cleaners are recognized across the injection molding industry as a safe, thorough alternative to manual scrubbing, which is a time-consuming process that can damage highly finished mold surfaces while missing contaminants in blind holes, cavities, cores and pins.
The contaminants produced by injection molding operations are tenacious. Examples include flashing, mold release compound, burned-on plastic residues, carbonization and vent outgas residue that if not safely removed will quickly shorten mold life.
The solution is the powerful cavitation action of an ultrasonic cleaner that creates millions of minute bubbles in an ultrasonic cleaning bath comprised of water and a biodegradable ultrasonic … Read the rest
Ultrasonic Cleaners for Medical & Surgical Instruments
Medical and surgical instruments in a variety of sizes and complexity can pose challenges when it comes to cleaning, disinfecting and sterilizing them after use. An ultrasonic cleaner is an ideal tool for the first step in this three step process to protect medical personnel and patients from possible infection due to pathogens that remain on the instruments after a procedure.
The Ultrasonic Principle
Ultrasonic cleaners work on the principle of cavitation whereby ultrasonic transducers create billions of minute air bubbles in an ultrasonic cleaning solution. These implode with violent force when they come in contact with objects placed in the solution and strip away contaminants without damaging the objects. When medical and surgical instruments are properly prepared for the ultrasonic cleaning step the process is fast, thorough and efficient.
Pre-prep is important, according to the Association of PeriOperative Registered Nurses (AORN) Recommended Practices Committee, which states that “initial instrument … Read the rest
Density Determination Kit Helps in Accurate Analysis
Determining the density of a solid or liquid is easier and more accurate when using a density determination kit with an analytical balance. Analytical balances such as the Kern ABS, AES and ABT models available from Tovatech can be programmed to work in concert with density determination sets, showing the density directly on the analytical balance liquid crystal display.
These density determination kits work on the buoyancy method, based on Archimedes’ Principle and recognized for a high degree of accuracy. As an example, 10 cm3 glass plummet is used for measuring the density liquids, giving a resolution of 0.0001 g/cm3. The density is determined from the weight of the plummet in air and its weight in the liquid being measured.
For solids, the density is the ratio of the object’s weight in air and its volume. Volume is determined by the buoyancy of the sample when immersed … Read the rest
