The Quaternary Valve is a manifold assembly where due to its structure the four channels from the valves all join at one point to the common port (the central port of the below picture). The lengths of the four channels are the same and the flow rate of each is almost identical. This structure is designed to maintain a high accuracy of the mixing ratio of multiple liquids. The product is often used to mix several kinds of eluant gradually in a low pressure gradient unit in liquid chromatography. In addition, it can be used to mix liquids accurately or to dispense equal amounts of one kind of liquid.
Since high processing accuracy is required, at the junction of the four channels, the manifold bases of almost all conventional models are manufactured by machining which results in an increase in cost. With advanced moulding techniques TAKASAGO has achieved the moulding of this junction in PEEK, and for this reason we are pleased to offer the Quaternary Valve at a competitive price.
Due to the moulding, the surface of the channels is very smooth also each diaphragm valve is individually replaceable. It is also possible to customise the Quaternary Valve for example to improve the response time of the solenoid valves on request. Please contact Orion Valves at www.orionvalves.co.uk for further information on the Quaternary Valve.
The piezoelectric micro pump is a miniature, slim and lightweight micro pump which enables a continuous micro fluid delivery. Self priming, low noise, low magnetic noise and low power consumption can be achieved using the piezoelectric micro pump. A number of options are available, including a highly inert version on request.
