Lab water systems provide high purity water
R
ephile’s Direct-Pure EDI (Electrodeionization) lab water system produces Type II water directly from tap water. Type II pure water can be used in many areas and typical applications are the preparation of culture media and preparation of solutions for chemical analyses. Consistently high quality water The Direct-Pure EDI system incorporates an Ion-Pure EDI module and stringently selected RO membrane to consistently deliver high quality Type II water at a relatively low cost. Resistivity of the product water is above 5MΩ·cm at 25°C, which meets or exceeds Type II water quality as defined by ASTM, CAP, CLSI and ISO 3696 / BS 3997, and also complies with the Purified Water requirements from the European and U.S. Pharmacopoeia.
tank (upgradable to a 60-litre), a liquid level sensor and a tank vent filter with carbon dioxide scavenger to prevent air-borne contamination of the EDI water. Flexible & easy-to-use The water dispenser handle is 360 degreerotatable and detachable from its support for effortless and instant dispensing with maximum flexibility. Volumetric dispensing and calibration can be easily set up on the dispenser. Electrical and water compartments are completely separated ensuring safe operation. Full document support is available to meet users’ GMP, GLP, FDA and other certification.

Fully automated Direct-Pure EDI is a fully automated system which contains pre-rinse, a RO membrane fouling to prevent flush, RO membrane life monitoring, as well as many other quality control programs for convenient operation. The prefiltration system removes most particles, chlorine and organic compounds, providing complete protection of the RO membrane and EDI module.

lympus has announced the launch of a new slide scanner. The OCUS40, incorporating a top-of-line Olympus 20x X-line objective, has outstanding image quality and ease of use, providing digital scanning right where and when it is needed. With the OCUS40 autofocus function, any sample quickly becomes a sharp digital slide that can be shared without loss of quality, inside the user network or across the Internet. Being fully motorised, the OCUS40 can be controlled locally or by a remote operator, providing users with either a digital scan or a live image which can be moved and focused as desired. The superior image quality, fast scan time and remote access make this instrument the ideal choice for applications such as telepathology, frozen sections and education.
• Compact, portable and vibration resistant.
Scan, share and control your sample, anytime and everywhere

Stellenbosch University invests in a Metrohm IC system for its new CAF water and soil testing laboratory he new water and soil laboratory is an addition to the nine existing Central Analytical Facility (CAF) units at the University. The facility is equipped with Metrohm’s 930 Compact IC Flex coupled with a UV/Vis detector enabling easy quantification of anions and cations in aqueous samples. The UV/Vis detector is a pivotal addition to the system as it allows for the quantification of certain
Olympus launches a new single slide scanner
The OCUS40 offers: • Compact high quality and fast slide scanning • Continuous autofocus, for scans and Live Image • Intuitive controls using computers, laptops, tablets or phones • Network connection and internal storage for digital scans • Fully motorised Live Image, local or remote • Fully automatic readout of label and barcodes
Easy maintenance The pre-rinsing program starts automatically when a new RO membrane is installed so there is no need for users to set up additional cleaning procedures. The system is equipped with a 30-litre PE

anions in more complicated matrices such as sea water. This detector will enable analysis of sea water samples collected during research expeditions, which are carried out on a regular basis to Antarctica. Ions quantified include Br-, Cl-, F-, NO2-, NO3-, SO42, PO43- and cations viz. Ca2+, K+, Li+, Na+, Mg2+, NH4. The system is coupled with an autosampler which allows the system to run unattended, automatically filtering, and diluting, samples when necessary.

he Victor Nivo is a highperformance filter-based multimode plate reader system that can be equipped with all major detection technologies – absorbance, luminescence, fluorescence intensity, time-resolved fluorescence, fluorescence polarisation, and Alpha. It is a compact, light-weight instrument designed for life science research laboratories performing routine lowthroughout assays, or assay development work, and with diverse application requirements. The system’s software has a modern, workflow-oriented user interface that is easy to learn and includes predefined application protocols to get users productive quickly. In addition, MyAssays Desktop Standard software is provided for data analysis. The system incorporates a dynamic wheel system with space for storage of up to 32 filters. Filters are exchanged between the inner and outer filter wheels, so any individual filter can serve either excitation or emission lightpaths. As a result, there’s no need to install new filters when switching between assays, and filters can be locked within the system so they can’t be mislaid in the lab – ideal for multi-user environments. When fully-loaded, the filter system provides the flexibility to detect many dyes with better sensitivity and greater cost-effectiveness compared to a monochromator.
For absorbance measurements, there is a choice of either a filter- or a spectrometerbased system. Full spectrum absorbance measurements are ultra-fast – 230 to 1 000nm at selectable resolutions (2.0nm, 5.0nm, 10nm) in less than one second per well. The spectrometer system also allows for the detection of a wide range of dyes or measurement of samples with unknown absorbance spectra.
