8 New Cuvette for Accurate Low Volume Spectroscopy
BioDrop, a revolutionary microvolume cuvette provides a robust, accurate and affordable approach to low volume spectroscopy. BioDrop’s simple but elegant patent pending design has the same dimensions as a conventional cuvette but is manufactured in two halves that are held together using magnets. The precision machining guarantees that the path length is accurate to within a few microns. Its simple optical layout provides very high energy throughput which ensures that highly accurate measurements can be made over a wide dynamic range and, unlike alternative methods, only one path length is required for most experiments.
BioDrop is simple to use - lay it down flat, pull apart the two halves, pipette the sample onto the window and replace the top half. Then just load the cuvette into a conventional spectrophotometer and take the measurement. BioDrop can withstand the knocks and falls commonplace in the laboratory setting and its ergonomic design makes it easy to handle, even with wet gloves.
Available in 0.5mm or 0.125mm pathlengths, BioDrop can be used to perform UV/Visible spectroscopy on sample volumes as low as 1µl, ideal for life scientists measuring DNA, RNA and protein samples.
BioDrop is an exciting new product that overcomes many of the disadvantages of conventional low volume UV/Vis spectroscopy for life scientists. The innovative design makes BioDrop extremely easy to use, without the fear of breakage and without having to do any more dilutions!

New Generation of Benchtop pH Meters Launched
A leading manufacturer of benchtop meters, Horiba, is launching the LAQUA range, its latest generation of instruments using the expertise from a company that has been manufacturing pH meters for more than 60 years and sold more than 250,000 instruments.
The range marries high performance with stylish design, industry first, touch screen interface. Horiba has focused the development of the benchtop meter to provide durable user-friendly meters for the laboratory professional. Advanced functionalities and a huge array of electrodes provide high precision, reliable measurement with improved response time in a huge variety of applications - from routine measurement to coping with extreme conditions.
LAQUA series consist of single and dual channel meters that can measure the most commonly used parameters in electrochemistry as pH, ORP, Ion, Conductivity, Resistivity, Salinity, TDS and Temperature and up to six parameters simultaneously. LAQUA’s large capacitance touch screen panel can display easy to understand real time graph, digital or analogue values.
The meter can be calibrated in five points, and has automatic standard solution recognition function for NIST/USA buffer as well as a customisable standard setting, it also complies with Pharmacopoeias standard.
Up to 2,000 data sets can be stored on the device’s internal memory. Data can be saved on to an external memory stick or transferred to a computer via RS-232 or USB connections, and Horiba provides free of charge data acquisition software. Fully GLP/GMP compliant, the LAQUA can be connected to an external printer. To ensure traceability, data is linked to sample name and user ID as well as calibration information. User account can be created and can be protected with a pin code. The Auto diagnostic function and the electronic user guide with colour pictures are useful feature that allow high performance and reliable measurements at any time.

UK manufacturer, LTE Scientific has recently launched a brand new and improved family of cooled incubators to replace its Qualicool range.
The stylish new IC range combines contemporary cabinet design with solid, reliable performance. In addition, all models use refrigerants R290 and R600a which have a Global Warming Potential (GWP) of just 3. This compared with lower energy consumption will help lower running costs whilst reducing your carbon footprint.
Accurate temperature performance and space-efficient storage capacities are key features of the new IC range. All IC Cooled Incubators incorporate a quiet and effective fan circulation system which distributes the air evenly throughout the chamber. All models are designed to operate between +2ºC and +50ºC.
4 sizes are available, and all models can be supplied with either a white epoxy coated or stainless steel exterior finish. Additionally all models can also be supplied with double-glazed glass doors. Interiors are high impact-resistant and durable ABS. The entire range also has a one piece door seal which can be easily removed making the whole cabinet extremely easy to clean.
A major feature of the benchtop/underbench IC200 model is its impressive usable chamber capacity of 92-litres, which makes it one of the largest under-bench cooled incubators available. In addition, the IC200 range can be stacked, thus making good use of floor area in the laboratory. The IC400 has an impressive 294-litre capacity yet it only takes up 595mm x 640mm floor area.

For easy maneuverability, IC400 and IC600 models are supplied on castors as standard. IC Cooled Incubators are controlled via an electronic PID controller providing close temperature control and variation throughout the chambers. For added safety, over-temperature protection is provided via a class 2 limiter.

The Council of Gas Detection and Environmental Monitoring (CoGDEM) is helping to organise the gas detection zone which will focus on new technology and products to detect hazards such as exposure to low oxygen levels in confined spaces and to toxic and flammable gases in the workplace. CoGDEM’s Leigh Greenham said “This year there will be more stands featuring gas detection technology as well as hazardous area (Ex) products, in addition to a wider range of free workshops covering topics such as ‘bump-testing versus calibration’, ‘confined space entry’, ‘VOC detection’ and much more.”
New gas detection techniques will be on show and the new ‘CoGDEM Guide to Gas Detection’ hardback book will be launched at the event. Many of the world's leading gas detection experts' products and services will be on display at the WWEM 2012 exhibition, including Air Products, BOC/Linde, Crowcon, Draeger, GMI, GfG, ISC, Infratec, Scientific & Technical Gases and Sira.
WWEM organiser Marcus Pattison is delighted with CoGDEM’s participation. He said “With so much taking place during the two days, WWEM 2012 will be a hive of frenetic activity, but with free entry, free parking and free lunches and refreshments for pre-registered visitors, we have tried to remove as much of the stress, hassle and cost associated with other events.”
