62 A Unique Portable System for Environmental Measurements
WTW, a Xylem company, is a manufacturer of portable systems for environmental measurements. WTW’s line up includes the waterproof (IP 67) Multi Line®
3410, 3420 and 3430 handheld meters for either one, two or three parameters at the user’s choice and
a range of Intelligent Digital Sensors (IDS) for pH, conductivity and dissolved oxygen measurement. The pH sensors and conductivity cells are based on WTW`s proven SenTix and TetraCon models, whereas the FDO®
925 optical D.O. sensor is an entirely new development.
These unique sensors convert the analogue measuring signal into a digital one before transmitting it to the meter. The digital signal is insusceptible to interference and hence allows the user to use cable lengths of up to 100 m even with pH sensors. In addition, particularly thin and supple cables can be used. Each IDS sensor stores a set of individual data (e.g. serial no. and, most important, its calibration record) for documentation purposes and thus minimising potential error sources and allowing to exchange the sensors between different meters at any time.
A true highlight are the new plug head versions of the IDS sensors that can be clipped to cables of different lengths at the user’s choice. They can be connected not only to the MultiLine® be used with the inoLab®
series of handheld meters, but also to the extraordinary new MPP 910 IDS and MPP 930 IDS depth sondes. Last but not least they can 9310, 9420 and 9430 laboratory instruments, too. No other system provides such a flexibility.

High Grade Deep Well Plates
Deep well polypropylene microplates from Porvair Sciences are shown in a new applications report to contain almost no significant levels of leachable or extractable compounds which might affect the integrity of stored samples.
The report shows the result of GC/MS analysis carried out by Porvair Sciences on a wide range of different manufacturers’ polypropylene deep well plates to establish levels of extractable or leachable contaminants in each of them. While the Porvair plates showed no significant contaminants many of the deep well plates from alternative sources showed contaminating peaks from chemicals used in the polypropylene to assist the injection moulding process.
Manufactured under class 10,000 conditions from ultra-pure grade polypropylene, Porvair deep well plates contain no contaminants that may leach out and affect stored samples or cell growth. For sensitive biological applications - Porvair offers a selection of deep well plates that are available certified as RNase / DNase free. Available in a choice of formats, volumes and well shapes - Porvair deep well plates are precisely manufactured to SBS/ANSI dimensions ensuring complete compatibility with microplate washers and automated equipment.
