LSP-500 Laboratory-Scale Processor

LSP-500 Ultrasonic Processor, Batch Setup with FBH Barbell HornLSP-500 Ultrasonic Processor, Batch Setup with CH HornSYSTEM OVERVIEW

The LSP-500 laboratory ultrasonic liquid processor is designed for small scale process testing and optimization. It outputs up to 500 W of acoustic power into the processed liquids and operates at the frequency of approximately 20 kHz. The processor is supplied with a 500 W ultrasonic generator, an air-cooled transducer, a CH-type converging horn and/or FBH-type Barbell horn, as well as an optional flow-through reactor chamber (flow cell).

The 500 W generator has rugged internal circuitry and ensures a continuous resonant frequency lock during operation. Pulsed processing is possible, where ON and OFF pulse duration can be set independently from 1 second to 59 seconds. The generator's LCD display features programmable operation allowing the user to set processing parameters, such as the ultrasonic amplitude, processing time and pulse ON/OFF times. The display also allows monitoring the output power, elapsed processing time and accumulated energy delivered to the sample. Constant ultrasonic vibration amplitude is always maintained, regardless of the power draw, which is automatically adjusted to compensate for variable loading conditions. The amplitude level can be adjusted from 20 to 100 %.

The LSP-500 processor is most commonly implemented in the batch processing mode, as shown in the above photos. Sample volumes in the range of 30 ml - 150 ml can be treated with the CH-type ultrasonic horn (12.7 mm output tip diameter, amplitude up to 107 microns). Larger sample volumes, in the range of 150 - 1,500 ml, require the FBH-type Barbell horn (21 mm output tip diameter, amplitude up to 90 microns). Larger samples can be treated in the flow-through mode, as described below.

FLOW-THROUGH CONFIGURATION

The LSP-500 processor can also be utilized in the recirculating flow-through mode, as shown on the left. This arrangement requires the FBH-type Barbell horn (21 mm output tip diameter, amplitude up to 90 microns) in combination with the stainless steel flow-through reactor chamber (flow cell).

 In the flow-through mode, the system can be used for processing several liters of liquid. The LSP-500 processor is not, however, recommended for continuous operation or processing large volumes of liquid. 

The LSP-500 processor is most commonly used to carry out small-scale testing and optimization with the intention to scale up once feasibility has been demonstrated. With this in mind, ISM also offers bench and industrial-scale ultrasonic liquid processors, BSP-1200 and ISP-3000, which permit implementing the processes in pilot or commercial production environments and feature continuous (24/7) flow-through treatment capabilities.

All ISM's ultrasonic systems are designed to provide direct scalability. This means that as the procedure is transferred from the LSP-500 to the BSP-1200 or the ISP-3000, the processing rate (the amount of liquid treated per unit of time) is dramatically increased, while all local exposure conditions (ultrasonic amplitude, cavitation intensity, time spent in the active cavitation zone, etc.) remain the same. As a result, the quality of the final product remains at the optimized level.

Commonly, when a process is transferred from a smaller to a larger ultrasonic system based on our Barbell Horn Ultrasonic Technology (BHUT), the productivity increase factor is a known number. This guarantees reproducible and predictable results at any scale of operation, from laboratory to industrial.
