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 synthesising 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. u
