Burkert’s innovative Type 6650 3/2 isolation valve uses patented flipper technology to set a new benchmark for miniature solenoid valves employed in clinical, life-science, analytical and fluid handling equipment. Suitable for use on vacuum, at up to 7-bar, and providing medium isolation for aggressive fluids, the direct-acting Type 6650 - at just 4.5mm wide - is a significant step towards miniaturisation, while outperforming comparable 10mm and 16mm designs.

The Type 6650 provides the ideal solution for manufacturers with valve applications requiring fast response times, high reproducibility, zero pumping and excellent flushing characteristics. The valve’s optimised design ensures reproducible and precise dosing, effective rinsing capability, and is suitable for use with aggressive chemicals.

Key to the performance of the Type 6650 valve is Bürkert's patented Flipper Technology. This employs an elastomer element which moves between two opposite valve seats under the force of permanent magnets fixed to the flipper element; opening one as it closes the other. This operation requires only a temporary pulse, so is characterised by its short response time. It also provides benefits in terms of high reliability and very low levels of wear.

With the two nominal sizes 0.4mm and 0.8mm available, and both 2/2 and 3/2 functionality, the Type 6650 is ideal for applications where the highest fluid performances are required in the smallest space – in dosing for example where the Type 6650 opens up new possibilities, in particular, in connection with 384-well Microtiter plates.

The Type 6650 is ably equipped for use in its target markets; both the new 3/2 valve and the 2/2 variant, which was launched in 2008, have bodies manufactured from high performance PEEK and seals made of FFKM.

Burkert’s MicroFluidic Range

The Type 6650 is the latest introduction to Burkert’s MicroFluidic range of products for analytical, medical and biotechnical applications. The range includes miniature solenoid valves and micro-pumps for applications with neutral, aggressive and highly purified media. These products are extremely proficient in the handling of fluids where dead legs, internal volume, chemical resistance and precision are paramount.

Burkert supports its MicroFluidic range with many year’s of experience of application environments which cross a spectrum of industries, including clinical diagnostic technology, DNA synthesizing and medical instruments to high-throughput lab automation, industrial ink jet and analytical instruments. Ultra-pure water, aggressive solvents, biochemical substrates, highly concentrated acids or dyes, different viscosities, fast drying industrial inks or crystallising fluids are just some of the wide range of flow challenges to which the company provides solutions.
