34  LMS  Issue 4 | 2014 Liquid Handling/Analysis 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. ⚛ Wirsam Scientific Tel:  011-482‑1060 / 021-386‑9020 / 031-709-0199 / 041-365‑2060 / 016-931‑1731 Email: [email protected] 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. ⚛ Merck Millipore Field Marketing Manager: Russel Mills Tel: 011-372-5059 Email: [email protected] 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. ⚛ Labotec Tel: 011-315-5434 Fax: 011- 315-5882 Email: [email protected]
