FLUORESCENT PROBES Detailing more than 2,900 products, handbook contains comprehensive technical and application details and includes information on dyes; labeling technologies; antibody conjugates; and proteomics, genomics, and high-throughput screening applications. Molecular Probes,



Instruments and labware

RAMAN ANALYZER For in situ detection of chemical reaction species, system utilizes an integrated 785-nm laser that is transmitted to the sample via a fiber-optic probe and can monitor crystallizations and, in particular, polymorph and solvate formation. Mettler Toledo,

ULTRAFAST SPECTROSCOPY Femtosecond transient absorption spectrometer can be used in many fields, including electron-transfer studies and molecular electronics, and is capable of acquiring a complete wavelength-time-absorbance data file in 30 minutes. Ultrafast Systems,

EXTENSIONAL RHEOMETER For measuring elongational properties of fluids such as polymer solutions, suspensions, melts, adhesives, and emulsions, product analyzes the thinning and breakup of a fluid filament and is ideal for applications related to adhesives, food products, consumer goods, resins, surfactants, and polymers. Thermo Haake,

FILTRATION PROCESSOR Autosampler system utilizes state-of-the-art ultrafiltration cell and is particularly suitable for light- to medium-particle samples such as drinking water, surface water, wastewater, digestion solutions, and extracts. Metrohm-Peak,

GAS ANALYZER Applicable to all IR-active gases and vapors, system is based on FTIR spectroscopy and features stainless steel, long-path gas cells and mirrors, sensitivity at the parts-per-billion range, and a fast response time in seconds for contamination detection. CIC Photonics,


Plant equipment and materials

PUMP/MIXER Developed for viscous materials, open-hopper progressive cavity pump incorporates a high-volume auger and induction chamber and is capable of handling viscosities of up to 700,000 centipoise. Seepex,

PADDLE DRYER Used for indirect heat-transfer applications requiring heating, drying, or cooling, system can be used on slurries, sticky paste, cakes, granules, or powders, and its twin agitator design allows for uniform mixing and high heat-transfer rates. Komline-Sanderson,

SIFTERS Employing four to nine sieve frames in stacked screen configuration and constructed of stainless steel, units offer gentle gyratory motion to reduce product degradation, as well as a pneumatic-sieve compression system to speed access and simplify sanitation and maintenance. Great Western Manufacturing,
