The Water Analysis Solution
F
or over 17 years Eutech Instruments has been a leading ISO9001certified company dedicated to the
design and manufacture of sensor-based
instruments for water quality analysis.
Underlying Eutech’s objective to be
a world leader in the field of water
analysis instrumentation, the company
adopts a proactive stand in anticipating
the needs of the industry.
They have a comprehensive product
line as a result of the creation of a
unique line of microprocessor-based
instr uments and chemica l sensor
systems that feature signature Eutech
intuitive designs that set it apart from
other brands on the market.
They also offer a comprehensive range
of laboratory and field instruments for
electrochemical and photometric water
analysis. This includes continuous
online process instruments for the
monitoring and control of pH, conductivity, total dissolved solids (TDS),
redox potentia l (OR P), dissolved
oxygen (DO), temperature, ion concentration analysis, chlorine and other
water quality parameters.
Eutech products range from compact
pocket testers and portable meters to
research-grade benchtop meters and
industrial process controllers, packed
with advanced user-friendly features.
This company has gained international
recognition for its achievements in sensor
technology, software programming and
product design. The extensive product
line also includes instruments with
proprietary patents and trademarks. ⚛

Handy in the Laboratory
B
rand ’s HandyStep® electronic
adds ergonomics and ease-of-use
to repeat pipetting. It is an electronic,
motor-driven repeating pipette compatible with most standard syringe tips,
including Brand PD-Tip™ syringe tips,
Eppendorf® Combi-Tips® and CombiTips Plus, Fisherbrand dispenser tips
and VWRbrand Combi-Syringes.
The HandyStep utilises a unique
tip-recognition system that automatically identifies the new encoded Brand
PD-Tip syringe tips.
The rugged mechanism reads the
specially coded plungers and displays
the nominal volume of the tip, the
default dispensing volume and the
corresponding number of dispenses
upon insertion.
Due to its broad tip compatibility, it
can dispense any volume between 1.0µl
and 50ml, including non-standard
volumes such as 9.2µl.
The HandyStep electronic features three operational modes namely,
pipette, dispense and an ergonomic,
intuitive auto-dispense mode that
eliminates up to 97% of repetitive
motion from repeat pipetting. No timeinterval programming is needed.
All aspects of operation are shown
clearly on a large LCD screen, which
features a counter to assist users with
repetitive dispensing applications. It
also operates with a relaxed grip that is
comfortable in either hand.
A subtle squeeze of the control
button under the index finger actuates all aspirating and dispensing.
The adjustable-speed motorised drive
ensures fatigue-free pipetting, reduces
the risk of repetitive motion injuries and
improves precision. ⚛

Pump up the Lab
H
eidolph of fe r s a n ef fe c t i v e
pumping solution for all laboratory needs. With flow rates from 0.005
- 4.151ml per minute, their peristaltic
pumps are suitable for high viscous
media.
In addition, there is a variety of
tubing material to choose from so
that the most appropriate variation
can be matched to specific
research needs.
These pump drives can be configured for multi-channel use to increase
throughput by running up to 12 individual cassettes on one single pump
drive and pump head system.
In addition to the standard pump
heads, which feature a four-roller
system, one can choose eight roller
pump heads for low pulsation.
Tubing and cassette changes are done
quickly and easily, with separate metering into multiple vessels with different
feed rates in a single operation by using
different tubing dimensions to adjust
the flow rate.
Heidolph helps to reduce maintenance costs with a sealed housing that
protects the pump from internal
corrosion.
This results
in an increased
lifespan of 10
years on average
at a reduced
maintenance
and repair cost.
They also offer
a three-year
warranty.
The peristaltic
pumps are
self-priming
and provide
care-free
operation.
The PD 5201
and PD 5206
offer different
setting
possibilities. ⚛
