The new Spectroblue sets new standards among compact, mid-range ICP-OES spectrometers for simplified operation, low maintenance, and high sample throughput while achieving the lowest cost of ownership in its class. The plasma generator uses novel air-cooled technology that eliminates the need for expensive external cooling. The new and unique OPIAir axial optical plasma interface needs no external cooling either, and offers sensitivity improvements of up to six times compared to conventional radial plasma observation, achieving detection limits at parts per billion levels. At the same time the generator's ample power reserves enable it to handle extreme sample loading while providing exceptional uptime, stability, and reliability. Spectro's unique UV-PLUS sealed optical system virtually eliminates gas purging. The Paschen-Runge optical layout combines high optical transparency with a wavelength range from 165 to 770 nm, and 8 pm resolution in the important analytical region from 165 to 285 nm for ease of processing line-rich spectra.


The QIAensemble Decapper automation system can facilitate the handling of liquid-based cytology and various other types of liquid samples that are processed by clinical laboratories around the world. This open platform system enables laboratories to automate many tedious manual steps required for unscrewing (or "decapping") the lids of clinical sample vials, extracting the sample material, pipetting it into testing vials, and then recapping the clinical sample vial. QIAensemble Decapper has a capacity to process up to approximately 800 samples per shift (excluding setup time and postprocessing requirements). It has been designed specifically for the handling and transfer of sample materials, and the addition of reagents. The instrument accommodates a variety of fluid types of variable viscosity for both samples and reagents. The software system, which is operated by an intuitive graphical user interface, provides laboratory staff with a comprehensive and user-friendly report for each run.


The Eppendorf Mastercycler nexus family of polymerase chain reaction (PCR) instruments offer excellent reproducibility, low noise emission, and the versatility to use all types of consumables. Up to three units may be combined for higher throughput, while software capability enables users to access a booking schedule for the instrument and receive e-mail notification when the PCR cycle is finished. Designed to be affordable, flexible, and reliable, the Mastercycler nexus incorporates Eppendorf's flexlid concept with automatic height adjustment of the lid. In combination with the universal block this allows use of the widest variety of PCR consumables, from large 0.5 mL tubes down to low profile plates and strips. The Mastercycler nexus gradient model provides a true gradient with 12 different temperatures and features SteadySlope technology to ensure that the heating and cooling ramp rates are identical in both optimization and routine experiments.


Moisture analysis is quick, easy, and accurate using the versatile Kern MLB 50-3N moisture analyzer. With a readout of 0.001 g or 0.01% moisture and connected to an optional companion printer, the MLB 50-3N moisture balance supports GLP/ISO record keeping data consisting of time, date, and sample identification number. Data include: Moisture content as a percent, current temperature, active drying process, previous sample drying time, and the switch-off mode by time or constant weight. Utilizing a 400 W halogen heater the MLB 50-3N moisture analyzer has a temperature range of 50°to 160° a maximum weighing capability of 50 g, reproducibility of 0.003 g, and linearity of ±03 g. Technicians can select four heating profiles—standard, soft, fast, and step—based on the properties of the material being tested.


The OmniPrep Soil DNA kit is designed for the rapid extraction of polymerase chain reaction (PCR)-ready DNA from environmental samples. The kit provides all the reagents necessary to isolate DNA samples ready for PCR from a large variety of environmental samples. The OmniPrep Soil DNA kit is primarily designed for use with environmental samples that contain a high humic acid content. This includes difficult soil samples such as compost, manure, and sediment. A major issue with high humic acid samples is that the humic acids, as well as metals and polysaccharides, inhibit subsequent PCR. OmniPrep Soil DNA SoilOUT columns remove these interfering agents, thus allowing for successful PCR. The kit applies a rapid precipitation technique that uses unique precipitation reagents to isolate genomic DNA free from proteins and RNA. Pure genomic DNA is isolated in about 60 minutes. The resulting genomic DNA is passed through the SoilOUT columns to remove the humic acid and is then ready for PCR.
