Ultrasonic Sieve Cleaners Efficiently Clean Analytical Sieves
Sieves made of ceramic, brass and steel are used in labs to understand the chemical and physical 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. Research labs use ‘analytical’ sieves since they have a mesh with extremely small dimensions of 200 mm or less.
Organic and inorganic materials like coal, sand, soil, feldspars, crushed ore, granite, clay, seeds and grain, etc undergo sieve analysis as it is a very simple method of deducing particle sizes. Cleaning sieves with larger mesh dimensions is very easy. 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. So, a few small and easy steps are sufficient to get these sieves ready for future tests.
However, fine and coarse particles tend to get trapped in the analytical sieves' very fine mesh. The problem is they reduce the accuracy of future tests unless they flushed out periodically. Constant use can cause these cleaners to become extremely dirty because of the intrinsic properties of the test substances that are studied for experimental purposes.
Analytical sieves require vigorous cleaning due to their extremely small crevices. The 200mm diameter sieves are the most common. They are mainly used for sieving chemical compounds, a samples of manufactured powders, soil and cement. The best way to clean them is through ultrasonic cleaning. Contaminants of all sizes are effectively removed using ultrasonic cleaners. They produce ultrasonic waves that generate powerful vibrations through rapid cavitation to free the particles stuck in the sieve.
These ergonomic units allow full-immersion cleaning that are extremely easy to operate. Before, most of the ultrasonic cleaners manufactured could not accommodate a 200mm sieve for thorough cleaning . However, sophisticated and efficient ultrasonic cleaners manufactured today have have simplified the normally tedious task of cleaning analytical sieves. A 200 mm diameter, eight-inch sieve can substantially be placed in these stainless steel-made cleaners. Their average capacity is nearly a gallon and a half or nearly six liters.
Among the high-end units available in market is the ultrasonic sieve cleaner that comes with a built-in rotation holder. In a busy lab, this is a productivity boon. Four sieves can be fitted into the holder and cleaned simultaneously. It has a volume of nearly seven and a half gallons or twenty eight liters. The added function of rotation produces better results since it makes the entire cleaning extremely intensive. The cleaning process is also faster using this ultrasonic cleaner. When compared with cleaners that lack rotation holders, this combined technology incorporated into one unit saves the lab a lot of time and money.
