New Products Conical centrifuge tubes Thermo Fisher Scientific Inc. introduces new 15 and 50ml Thermo Scientific Nunc conical centrifuge tubes. The 15/50 ml conical centrifuge tubes are ideal for any laboratories within academia, government, biotechnology and pharmaceutical research. Incorporating a new plastic rack design that is reusable, collapsible and recyclable, the 15/50 ml tubes are offered with an environmentally friendly, space-saving storage solution. This design provides a cleaner option for use in cell culture and biological safety cabinets by reducing any potential risk of particle contamination. The new tubes also feature the largest writing area in the industry, which enables researchers to clearly label their research for increased sample traceability. With a leak-proof design the tubes are certified USP Class VI, non-pyrogenic, non-cytotoxic and RNase/DNase-free to ensure consistently high-quality results are obtained. The 15/50 ml tubes also have a higher RCF rating, which enables a broad range of applications requiring low-speed to super-speed centrifugation protocols

Analyzers
Oscilloscopes AEMC® Instruments introduces its’ third generation of self-contained, hand-held, two and four-isolated-channel oscilloscopes (100MHz and 200MHz bandwidth models are available). The oscilloscope features five complementary tools in one, an Oscilloscope, FFT analyzer, 4-channel TRMS multimeter, harmonic analyzer and a recorder. The Model OX 7100 (100MHz) and OX7200 (200MHz) series Oscilloscopes are rugged and ergonomic instruments that can be used in both the laboratory and in field testing. Ideal for field use, they utilize the patented, new system of “plug-and-play” accessories, isolated measurement channels and a range of remote management capabilities. The Ethernet link lets you remotely control the oscilloscope without loading any software on your PC. The large 320 x 240 full color LCD touch screen provides detailed graphical and alphanumerical representations of all measurements and also functions as a touch screen. The various “Windowslike” menus can be opened or pulled down and executed, using the convenient stylus. The stylus can also be used for direct action on graphic elements such as cursors, triggers and zooming.

Cartridges Biotage announces two new additions to its SNAP XL family of cartridges for large scale and development purification. Released in both 750g and 1500g sizes, the new cartridges offer solutions for reverse phase chromatography (KP-C18-HS) and also optimized silica for the separation of amines (KP-NH). The new cartridge sizes address a growing need for 100g+ scale purifications and offer chemists increased efficiency while reducing running costs. Additionally, the application of reverse phase flash chromatography and the separation of amines are growing trends in pharmaceutical drug development.

Reply Card #4416 Shimadzu Scientific Instruments introduces the TOC-L Series of analyzers for total organic carbon testing in aqueous samples. With a wide sample range from 4 μg/L to 30,000 mg/L, the TOC-L is suitable for analyzing ultra-pure to highly contaminated samples of wastewater, brine water, seawater, drinking water and pharmaceutical water. Consisting of four models, including PC-controlled and standalone versions, the TOC-L uses Shimadzu’s 680° C combustion catalytic oxidation method to efficiently analyze all organic compounds. It features automatic sample acidification and sparging, as well as an automatic dilution function that reduces sample salinity, acidity and alkalinity. This significantly extends the use of catalysts and combustion tubes. The series also features variable syringe sizes when the sample volume is limited. High-precision mass flow controllers ensure uninterrupted carrier gas for accurate analysis. A zero-maintenance Peltier cooler used for maximum water vapour removal ensures accurate analysis. In addition, an on-board air purifier may eliminate the need for high-purity air during testing. Optional salt kits permit 12 times more salt to be analyzed before maintenance is required. The ASI-L autosampler can use three different vial sizes for various applications, while the smaller OCT-L autosampler can use any vial size for up to eight or 16 samples. TOC-L models can accept particulates up to 500 microns or 800 microns with the optional particulate kit. For larger particles, solids, soils and sludge, the SSM-5000 is the ideal solution. The TNM-L can be added for simultaneous TOC and Total Nitrogen analyses without increasing the size of the footprint.

SpectroSens Stratophase, a specialist in realtime chemical and biochemical measurement, has premiered its latest SpectroSens monitoring and data analysis control. Stratophase’s new device is a bench-top control centre capable of monitoring up to eight independent inline SpectroSens optical sensors. SpectroSens sensors employ an innovative technology that interprets changes in refractive index to provide real-time process monitoring. The new data monitoring unit provides a built-in touch-screen interface while reducing footprint by over 50 per cent. Due to its new ergonomic form and smaller size, the SpectroSens unit is perfectly suited for use in a range of environments, from a small process development laboratory up to industrial scale requirements. The multichannel capabilities of the device allow it to be connected to a number of SpectroSens sensors, whether in a single, multi-stage process or in situations where multiple processes are running in parallel.
