Ultrasonic Sieve Cleaners Deliver Superior Results For Cleaning Analytical Sieves
Steel, brass and ceramic sieves are used in labs to identify the physical and chemical properties of a wide range of solids. In order to study and determine the size and shape of the particles, fineness, flow characteristics, etc laboratories need sieves of different grades to carry out ‘gradient’ or ‘particle size distribution’ tests. The sieves used in research labs are referred to as ‘analytical’ sieves since their mesh is typically small at 200 mm or less.
Organic and inorganic samples of coal, sand, soil, feldspars, crushed rock, granite, clay, seeds and grain, etc undergo sieve analysis as it is a very simple method of deducing particle sizes. Sieves with larger mesh dimensions are easy to clean. All it needs is a gentle tapping on the sides of the frame of the sieve, cleaning it with a sieve brush followed by running a fine cloth over it. These small and easy steps are sufficient to get these sieves all set for future tests.
On the other hand, coarse particles tend to get stuck in the fine mesh of smaller analytical sieves. The problem is they reduce the accuracy of future tests unless they flushed out regularly. Constant use can cause these cleaners to become extremely dirty because of the intrinsic properties of the test substances that are studied and researched for experimental purposes.
Analytical sieves that have crevices with extremely small dimensions require vigorous cleaning. Most commonly used are the 200mm diameter sieves. Their main use is for sieving chemicals, a samples of manufactured powders, cement and soil. The most efficient method of cleaning them is through ultrasonic cleaning. Contaminants of all sizes are effectively removed using ultrasonic cleaners. They produce ultrasonic waves that creates powerful vibrations through rapid cavitation to free the particles lodged in the sieve.
These ergonomic units allow full-immersion cleaning that are extremely easy to operate. Before, most of the ultrasonic cleaners could not accommodate a 200mm sieve for thorough cleaning . However, state-of-the-art and efficient ultrasonic cleaners produced today have made the normally painful task of cleaning analytical sieves a very simple one. A 200 mm diameter, eight-inch sieve can easily be placed in these cleaners whose tank and cover are made of stainless steel. Their average volume is nearly a gallon and a half that amounts to nearly six liters.
One of the high-end units currently available in the market is the ultrasonic sieve cleaner that comes with a built-in rotation holder. In the busy lab, this is a productivity boon. Four sieves can be fitted into the holder and cleaned simultaneously. It has a capacity of nearly seven and a half gallons or twenty eight liters. Its rotation function delivers better results because it makes the entire cleaning highly intensive. The cleaning process is also faster using this ultrasonic cleaner. When compared with cleaners that lack rotation holders, this combined technology designed into one unit saves the lab a lot of time and money.
