MOULDED QUATERNARY VALVE For Cost Reduction of a Gradient Unit in a LC The Quaternary Valve is a kind of manifold valve where, due to its structure, the four channels from the valves all join at one point and connect to the common port. 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. The product is often used to mix several kinds of eluant gradually in a low pressure gradient unit in a liquid chromatograph. Since a high processing accuracy is required at the junction of the channels, the manifold bases of almost all conventional models, including those of other manufacturers, are manufactured by machining, which results in an increased cost. With advanced moulding techniques, TAKASAGO has achieved the moulding of this junction in PEEK, and we are pleased to provide our Quaternary Valve at prices conventional models cannot match. Various customisations are also possible, including improvement of the response time of the valves. Please feel free to ask us for the details. 2012 09 TAKASAGO ELECTRIC, INC. 66 KAKITSUBATA, NARUMI-CHO, MIDORI-KU, NAGOYA, 458-8522 JAPAN Tel +81-52-891-2301 Fax+81-52-891-7386 E-mail: [email protected] URL: http://www.takasago-fluidics.com/
