Confocal Laser Scanning Microscope

The FLUOVIEW FV3000 confocal laser scanning microscope combines high-performance imaging capabilities with ease of use, so scientists in such fields as cell biology, cancer research, and stem cell research can collect relevant imaging data quickly. The FV3000 offers flexibility for all live-cell imaging applications and provides high-resolution images of structures and dynamic intracellular processes. The FV3000 is controlled via a new, intuitive software interface so even novices can generate high-quality data and images. Objectives range from 1.25X to 150X magnification. Users can choose the FV3000 with the galvanometer scanner or the hybrid resonant/galvanometer scanner. The high-speed resonant scanner acquires high-resolution images at up to 438 frames per second, so scientists can observe fast-changing processes. Users have the freedom to select the exact wavelength range that they wish to capture in every detection channel at nanometer precision, and to change the scanning range or laser light midway through an experiment with millisecond precision.

Air-Bearing Rheometer

The Thermo Scientific HAAKE Viscotester iQ Air rheometer extends the capabilities and measurement range of the HAAKE Viscotester iQ product line to enable monitoring of very low-viscosity materials. Built-in Connect Assist technology provides real-time feedback that reduces operator errors and makes it easier for users to set up sample tests. The HAAKE Viscotester iQ Air rheometer is designed to acquire simple viscosity curves and complex rheological investigations in rotation or oscillation, covering measurements ranging from low-viscosity liquids to highly viscous pastes. It also provides a touchscreen interface for stand-alone routine measurement and a USB flash drive for extended capabilities; all modes are operated with full software control from a computer. Thermo Fisher Scientific offers a complete portfolio of rheology testing solutions. The Viscotester range has been specifically developed to meet the demands of rheological tasks in quality control, combining fast, reliable, and precise measurements with maximum ease of use.

Metal Catalyst Reaction Monitoring Probe

The inert Atmospheric Solids Analysis Probe (iASAP) enables chemists and chemistry students to ionize liquid and solid samples for analysis by mass spectrometer without the need for sample preparation. The technique allows a synthetic chemist to perform real-time reaction monitoring by simply dipping the iASAP into the reaction mixture and inserting the probe into the atmospheric pressure chemical ionization source of the compact mass spectrometer (CMS). Mass spectral data is presented within seconds. For air-sensitive compounds, such as metal catalysts, iASAP is a viable technique to prevent oxidization during the assay. The iASAP protects the compounds in inert gas as they are transferred to the CMS, enabling such measurements without the traditional need for glove boxes. Researchers led by Charles McEwen, Ph.D, at the University of Pennsylvania, and Ingo Krossing, Ph.D., at the Albert-Ludwig University of Freiburg, developed the iASAP.

Differential Scanning Calorimeters

A new line of differential scanning calorimeters (DSCs)—the Discovery DSC 2500, DSC 250, and DSC 25—features enhanced sensing technologies, resulting in unprecedented performance in baseline flatness, sensitivity, resolution, and reproducibility. At the core of every new Discovery DSC is the exclusive TA Fusion Cell, which incorporates design concepts from the Q-Series and first-generation Discovery DSCs, patented Tzero technology, and new proprietary manufacturing processes. All models come with an app-style user interface, TRIOS software, and automated calibration and verification routines that work seamlessly to improve laboratory workflows. Discovery DSCs are used for many applications, including materials science, pharmaceuticals, and chemistry. The DSC 2500 comes standard with all options, which include T4P heat-flow technology and a linear autosampler that assigns sample and reference pans to any combination of the available 54 positions. The DSC 250 is a configurable, research-grade DSC. The DSC 25 is a cost-effective, easy-to-use, general purpose DSC.

Seed Germination

Phytotc seed germination pouches are an inexpensive, space-saving alternative to pots and other containers. Phytotc has two parts: a plastic see-through pouch and a paper wick that fits inside the pouch. Seeds are placed in the trough formed by the paper wick. Water or nutrient substrates are then added. The pouch is finally placed in an upright position and the seeds are left to grow. An optional stand can hold multiple pouches. Most seeds grow in days. The pouches are available in small (14-cm high × 12.5-cm wide) for plants with fibrous or shorter roots; medium (18-cm high × 12.5-cm wide) for plants with tap roots or longer roots; and large (30-cm high × 25-cm wide) for plants needing longer growing times. All pouches come sterilized. They can be used in plant nematology, physiology, and pathology applications as well as for legume inoculation and tissue transfer.
