Product catalog summary
Overview: The UIS250L ultrasonic sieving tower by Hielscher Ultrasonics is designed to enhance sieving processes using ultrasound technology, particularly for fine materials where traditional methods may fail. This technology can be used for both dry and wet sieving and is compatible with existing sieving towers.

Specifications: The ultrasonic processor UIS250L operates at a frequency of 24kHz with automatic control and a power output of 250 watts. It supports power control amplitude from 20-100% and requires a power supply of 230V~, 2A, 48-63Hz, or 115V~, 4A, 48-63Hz. The transducer is housed in stainless steel, measuring Ø48mm in diameter and 160mm in length, weighing 1.2kg.

Technology and Components: The system includes a ring sonotrode that fits laboratory ring sieves (100mm to 400mm in diameter) and transmits oscillations to the screening surface. The ultrasonic components can be retrofitted and used alongside vibrators. An accessory set is required for a complete sieving tower, including a basic platform, tension bars, a bottom receiver, and a top cover.

Advantages: The ultrasonic excitation method is cost-effective and flexible, as it excites multiple sieves simultaneously without needing individual ultrasonic excitation for each sieve. The transducer's external placement prevents contamination of the material being sieved.

Applications: Suitable for laboratory use, the technology supports sieving of extremely small volumes with mesh sizes down to 5µm. Custom dimensions for ring sonotrodes are available upon request.

Ultrasonic Sieving for Laboratories UIS250L ultrasonic sieving tower The ultrasound technology is used for the acceleration of sieving processes classical low frequency vibrators. Especially in case of very fine materi- als ultrasound is often the only possibi- lity to enable the sieving process at Hielscher Ultrasonics has developed a worldwide unique technology especially for exciting common laboratory ring sieves (according to ring sonotrode that fits the sieve is excited by the ultrasonic processor UIS250L. The ring sonotrode transmits the oscillation via the sieve frame to the screening surface. With the help of the clamping fixtures the neighboring sieves are also excited. In contrast to the ultrasonic sieving processes known until now, in which each sieve needs its own ultrasonic excitation, this is a very inexpensive and flexible solution. Another advantage of this exciting principle is that the transducer is situa- ted outside the material to be sieved. This technology can be used for dry or wet sieving, as well as for cleaning the sieves. The ultrasonic components can be retrofitted in already existing sieving towers and can even be used in combination with vibrators. In this case the delivery scope consists only and the ring sonotrode, which will be fitted into the common laboratory ring sieves of most manufacturers (see complete sieving tower.
