The new Techne catalogue introduces new cooling products and the company's extended thermal cycler range. Over 50 full colour pages illustrate their temperature control and science equipment for life sciences, research, clinical and general laboratories. Two significant additions in the new catalogue will solve sample-cooling problems in many labs. The N°ICE electronic ice bucket contains ceramic-coated beads to support any shape vessel and the BL°CKICE cools tubes held in two Dri-Block inserts. Both maintain a set temperature in the 0°C to 40°C range. Their range of personal thermal cyclers is joined by the expanded capacity TC-3000X and the TC-3000F, a small gradient model. Users of standard thermal cyclers will welcome the appearance of the new-look TC-4000 and TC-5000. Also included in the Techne range are temperature-controlled water baths, Dri-Block heaters, cell culture equipment and molecular biology products such as hybridisation incubators.

Axiom Analytical's FDR-1800 Series NIR diffuse reflectance probes can be fabricated in virtually any length, providing the capability for process monitoring in full-scale batch reaction vessels. Such vessels often include glass lining or heating coils making probe entry from the side impossible. However, the new probes can be made long enough for top entry, even in the largest reaction kettles. A feature of the design is the use of Axiom's window sealing technique involving a direct sapphire to metal-welded pressure seals. A high degree of chemical resistance is assured because the only materials in contact with the process are sapphire, high nickel alloys and a thin flash of gold or PTFE. The compliance required to withstand extreme temperature cycling is provided by the nickel alloy seal which is compressed at high pressure prior to welding, eliminating fatigue and stress failures.

Bruker Biospin have launched two new ultra-high NMR magnets which, when combined with the Avance III spectrometer, will deliver improved sensitivity and resolution, enabling new research applications in structural biology research, membrane protein structure determination and a growing number of materials research applications. The two-story 900 MHz WB US2 expands the range of available shielded UHF wide bore magnets from 850 MHz to 900 MHz and combines the company's Ultrastabilised and Ultrashield technologies. The compact 850 MHz US Plus actively-shielded magnet can be placed in a single story laboratory, lowering the barriers for researchers to operate at this UHF strength. Its compact size and small stray field improve siting flexibility and reduce site preparation costs. This standard bore (54 mm) magnet also benefits from Ultrastabilised and Ultrashield technology for improved protection against external perturbations

Protea Biosciences has launched its new protein recovery technology platform, the GPR-800. The new benchtop instrument uses an advanced, proprietary, multi-channel microfluidic chip technology which allows the biologist to prepare “mass spectrometry ready” protein samples in less time. It uses a protein surfactant that solubilises the protein, then degrades it, eliminating any interference with the mass spectrometer. The plastic microchips allow recovery in a closed system, with minimal dead volume, ensuring no introduction of contaminants.

Pfeiffer Vacuum has won an R&D 100 Award for the development of its HiPace turbo­pumps. Pfeiffer Vacuum celebrated 50 years since their invention of the turbopump in 2008. www.pfeiffer-vacuum.de

Pfeiffer Vacuum has developed the HiCube turbo-pumping stations for applications in the fields of research and development, accelerators, analysis and surface physics as well as vacuum process technology, electron beam welding and leak detection systems. The modular design principal offers versatility that satisfies a wide range of requirements in the 35 L s–1 and 685 L s–1 pumping speed range. They offer a combination of a turbo-pump from the HiPace series and a dry or oil-sealed backing pump designed for the user's specific application needs and come fully configured and ready for immediate employment. All connections are consolidated at the rear of the unit, the turbo-pump can easily be removed from the housing and connected to a recipient or system, as all the individual components are easily accessible and oil changes are simple to perform on the rotary vane pumps without the need for any special tools.Pfeiffer Vacuum UKIssue: 21/01 RSN:

Andor Technology has announced the latest addition to their Shamrock series of spectrographs. The new Shamrock SR- 500i imaging spectrograph offers enhanced multi-track capabilities and imaging quality for simultaneous multi-fibre-optic probing and direct-coupling micro-spectroscopy applications. Configurable with up to two inputs and two outputs, the SR-500i is compatible with a wide range of accessories including the mirror-based F/# matcher, swappable grating turrets and shutter and fibre-optic bundles. The versatility of the instrument means researchers can easily tailor and upgrade their system to adapt to changing needs.

nLight has announced the expansion of its Pearl solid state laser platform into wavelengths from 879 nm to 888 nm with increased electrical–optical efficiency and power levels up to 100 W. Power levels up to 100 W are available at 879 nm, 885 nm and 888 nm with the company's PowerCore fibre at 400 µm or 600 µm and the increased operating efficiencies result in significantly less heat. Using Pearl with upper-state pumping of Nd:YAG or Nd:YVO4 enables the design and manufacture of air-cooled diode-pumped solid state laser systems. Due to the single emitter architecture, narrow spectral widths of less than 3.5 nm full width at half maximum can be maintained. nXLT diode technology enables long lifetime, even under harsh conditions with repeated on/off cycles, whilst the PowerCore fibre provides consistent beam quality and power transmission independent of fibre layout and ­movement.

For rare earth and nano phosphors, luminescent materials for white LEDs, displays, general lighting and scintillator applications, McPherson has developed spectral test stations for deep ultraviolet excited, real-time measurements. A high-resolution spectrometer configured for the 200–800 nm wavelength region is the centre point for the open architecture system. The system is equipped with a cooled 2D CCD detector, multi-channel scaler for persistence data collection, a vacuum sample chamber which is equipped with either monochromatic tuneable light source (120–200 nm) or selectable 146/147 and 172 nm sources, a horizontal sample tray which accepts up to 20 individual samples and computer optimised first surface optics for optimum focus and signal collection. The system, provided ready to run, is suitable for industrial quality control applications as well as rigorous research and development.McPherson, Inc.Issue: 20/06 RSN:

Hamamatsu Photonics has announced its new thermo-electrically cooled NIR modules. The spectrometer modules consist of a palm-top size polychromator with integrated optical elements, an InGaAs linear image sensor optimised for the required wavelength range and a driver circuit and integrated USB interface to allow simple PC connection and data acquisition. The modules are initially offered in two ranges. The C9913GC series features a spectral response range from 900 nm to 1700 nm using a standard InGaAs image sensor and the C9914GB series features a spectral response range from 1100 nm to 2200 nm using an extended response InGaAs linear image sensor. Both modules are supplied with sample software which allows the user to set the measurement conditions, acquire and save data and then display it graphically. Using the USB interface means that no external power supply is required so that, together with its compact size, it can even be assembled into portable ­equipment.Hamamatsu Photonics (UK) LtdIssue: 20/05 RSN:
