Chemicals and materials
DISPERSION Low-surface-tension resin dispersion is designed for use in waterborne adhesives, eliminating the need for surfactants or other wetting agents. No modification is required prior to formulation. Eastman Chemical Co., www.eastman.com
LATEX Redispersible powders for exterior insulation and finishing systems improve adhesion, water repellency, and freeze/thaw resistance. Rhodia Performance Coatings & Services, www.rhodia-pcs.com
ADHESIVES Hydrophilic heat-seal adhesives bond components and wick biological fluids in diagnostic medical devices. Products bind to a variety of polymeric substrates including polystyrene, polyester, and polycarbonate. Adhesives Research, www.adhesivesresearch.com
CAPILLARIES Coated capillaries for electrophoresis allow sample separation without sample loss through adsorption of sample to the tube walls. Inner diameters of 75 and 100 µm are currently available, along with specialized buffer solutions. Protea Biosciences, www.proteabio.com
LUBRICANTS Three new lightweight oils extend the life of hydraulic systems, bearings, chains, and valves. They are thermally stable and demonstrate excellent water separation, foam control, and rust protection. Henkel Corp., www.loctite.com
Instruments and labware
FLUOROMETER Four-channel detector uses line-emission light sources and narrow-band filters for discrete wavelength excitation. Flow cells are available in volumes ranging from 6 to 24 µL. System can be configured for either series or parallel detection. McPherson Inc., www.mcphersoninc.com
GENETIC ANALYSIS System provides high-throughput, quantitative gene expression via scalable, multiplexed PCR. It can run two 96-well plates in 24 hours and cost-effectively look at the expression of 20 to 35 genes in a single reaction per well. Software tools for automated primer design and multiplex assembly are included. Beckman Coulter, www.beckman.com
SPECTROMETER Laboratory device is designed for general-purpose FTIR spectroscopy, quality-control measurements, and service-lab applications. Features include 0.5 cm1 resolution, a choice of detectors, industry-standard software, and an optional beam-output port. Midac, www.midac.com
THERMOMETER Enclosed, temperature-buffered sensor accurately monitors temperatures in freezers, refrigerators, water baths, heating blocks, and incubators. Display can show high, low, or current temperature; digital memory monitors high/low readings for any set time period. Control Co., www.control3.com
WATER BATHS Deep-well compact baths provide stability of ±0.005 °C at temperatures from -80 to 300 °C. They feature a small footprint, a drain for easy fluid removal, and an overflow reservoir. Hart Scientific, www.hartscientific.com
SEALED CELL System allows the measurement of viscoelastic rheological properties of solutions above their boiling point or without any loss of volatile components. Measurements can be made under pressure, with full dynamic oscillation and viscometric capability. The air-bearing seal is effectively frictionless. ATS Rheosystems, www.atsrheosystems.com
FUNNEL Safety funnel is made from chemically resistant high-density polyethylene and features an improved vapor-resistant gasket, solids filter, latch, and screw cap. Device exceeds hazardous materials regulations requiring the prevention of chemical spills and vapor releases. California Pacific Lab Inc., www.calpaclab.com
Plant materials and equipment
INDICATORS Digital panel indicators for temperature- and process-display applications provide high accuracy and visibility in a compact housing. Easy-to-read LED display changes from green to red during an alarm condition. Units are modular and freely configurable via plug-in output boards. Danaher Industrial Controls, www.dancon.com
MIXER Single-use mixing vessel can be used to mix materials of any viscosity or density difference. It can be scaled to more than 10,000 L and features an integral perforated diaphragm that is moved up and down by a simple, low-cost mechanism. ILC Dover, www.ilcdover.com
MOISTURE EXCHANGER Unit is designed for humidifying or drying industrial gas samples, using membrane tubing to bring the humidity of a gas into equilibrium with the ambient air. It is corrosion-resistant and has no moving parts. PermaPure LLC, www.permapure.com
SLUDGE MONITOR Device uses sonar to determine the depth of a sludge blanket in a wastewater treatment system. Self-cleaning transducer has no moving parts, and the control unit features a menu-driven program that allows custom configuration. Clark-Reliance Corp., www.clark-reliance.com
ORGANICS ANALYZER Instrument uses combustion methods to accurately analyze carbon levels from 50 to 10,000 µg. Aqueous samples can be analyzed without sample preparation. Features include magnetic stirring, large sample pathways, and the ability to analyze samples over three orders of magnitude with a single calibration curve. OI Analytical, www.oico.com
