A lateral mode flow-through PMMA ultrasonic separator
A lateral mode flow-through PMMA ultrasonic separator
A flow-through lateral-mode ultrasonic standing wave separator constructed entirely from PMMA coupled to a piezoceramic transducer has been demonstrated for the first time. Use of PMMA allows for simple, low cost construction, with channels formed either by embossing at relatively low temperatures (120ºC) or by direct machining. A simple room-temperature solvent bonding technique is also reported suitable for closing the channel. Initial results using milk show that both construction techniques allow lateral modes to be established, with visual confirmation of separation of lipids within the milk, offering the promise of disposable continuous concentration devices.

Abstract
A flow-through lateral-mode ultrasonic standing wave separator constructed entirely from PMMA coupled to a piezoceramic transducer has been demonstrated for the first time. Use of PMMA allows for simple, low cost construction, with channels formed either by embossing at relatively low temperatures (120ºC) or by direct machining. A simple room-temperature solvent bonding technique is also reported suitable for closing the channel. Initial results using milk show that both construction techniques allow lateral modes to be established, with visual confirmation of separation of lipids within the milk, offering the promise of disposable continuous concentration devices.
