Miniature fluidic valves

Written by: Tom Austin-Morgan | Published:

Parker has released its R9 Diaphragm Rocker Isolation range of 9mm fluidic valves designed to improve the performance of clinical diagnostic, analytical chemistry and agent detection systems requiring high precision fluid control.

The compact nature of the R9 valve means it can be mounted over micro plates to eliminate the requirement for transfer lines, improving performance and saving space. Parker claims the valve offers the flow typical of a 16mm valve in a 9mm width and typical applications include in-vitro diagnostics, haematology, molecular diagnostics, flow cytometry, genomics, proteomics, liquid handling, sample preparation, chromatography and high precision flow control.

When mounted on a manifold, the R9’s reduced footprint is said to facilitate smaller and more efficient fluidic circuits by consuming less space and shortening fluid channels. R9 valves also feature low carryover and low internal volume, with good particulate resistance. Capable of operating with a variety of flow and pressure ratings up to 6.8bar, R9 valves support the use of smaller fluid passageways, reducing fluid consumption and increasing throughput.
