Burkert has released its second generation of miniature flipper valve, an addition to the Burkert Microfluidic range of products for analytical, medical and biotechnical applications.

The optimised internal design enables effective flushing of media through the device, in a way that was only previously possible with rocker valves.

This eliminates the waste of reagents, as well as preventing cross contamination and increasing process safety.

The flushing characteristics of the second-generation flipper valve are related to the valve internal volume, and more principally to its internal design.

The internal volume of the Type 6650 flipper isolation valve is two times smaller than the Burkert Type 0127 rocker valve.

The valves have short, reliable, response times with high repeatability and excellent flushing characteristics, the company said.

They are particularly suitable for the handling of liquids with micro plates where high-precision dispensing and small dimensions are required.

The Type 6650 is the latest introduction in the Burkert 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.

Suitable for use on vacuum up to 7 bar, and providing medium isolation for aggressive fluids, the direct-acting Type 6650 is 4.5mm wide and outperforms comparable 10mm and 16mm designs.

The optimised design of the valve ensures reproducible and precise dosing, effective rinsing capability, and it is suitable for use with aggressive chemicals.

Key to the performance of the Type 6650 valve is the Burkert Flipper Technology.

This employs an elastomer element that 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 and provides high reliability and low levels of wear.

With the two nominal orifice sizes of 0.4 and 0.8mm available, and 2/2 and 3/2 functionality, the Type 6650 is suitable for applications where the highest fluid performances are required in the smallest space.
