Instruments and labware

AUTOSAMPLER Temperature-controlled multistirrer assembly can handle both 20- and 40-mL vials. Each vial position has its own stirring mechanism, eliminating variability caused by the dissolution process. Viscotek, http://www.viscotek.com

WEIGHING Analytical balance is designed to measure powders accurately up to 62 g, automatically sensing changes in ambient temperature and recalibrating in response. Features include a backlit LCD display, a full range of standard weighing units, and menu-driven navigation. Alliance Scale, http://www.alliancescale.com

GLASS VIALS Certified sample vials for high-performance liquid chromatography and gas chromatography analysis meet the tightest dimensional tolerances and are certified to be contaminant-free. Waters Corp., http://www.waters.com

RHEOMETER System is designed for testing any rheologically significant materials such as thermoplastics, thermosets, elastomers, semisolids, and fluid systems. This instrument will perform steady, transient, and dynamic shear measurements using parallel plate, cone and plate, rectangular torsion, dynamic tension, and other fixtures. ATS RheoSystems, http://www.atsrheosystems.com

SAFETY FUNNEL Inexpensive chemical-waste containment system exceeds regulations requiring the prevention of laboratory chemical spills and toxic vapor releases. The funnel is manufactured with chemical-resistant high-density polyethylene and features an improved vapor-resistant gasket, a solids filter, a heavy-duty hinge, and a screw cap. California Pacific Lab, http://www.ecofunnels.com

CENTRIFUGE Benchtop instrument provides fast separations and optimal recovery in a large- capacity rotor. It can accommodate microplate carriers, as well as adapters for direct centrifugation of cell culture flasks, and automatically detects and corrects imbalances. User-friendly prompts and a numeric keypad enable direct entry of values. Beckman Coulter, http://www.beckmancoulter.com

Plant materials and equipment

DRUM CONTAINMENT Portable, self-contained system uses multiple barriers to allow toxic or explosive powders to be transferred directly into process equipment without cross-contamination or personnel exposure. De Dietrich Process Systems, http://www.ddpsinc.com

AIR CLASSIFIER Excellent particle-size selectivity and exact internal product flow are key characteristics of this device. A complete system can be provided with a feeder, cyclone, filter, blower, and control panel completely installed on a base frame. Netzsch, http://www.netzschusa.com

GAS FLOW This flow measurement system has ±0.15% standardized accuracy and is dry (no mercury, oil, or soap solution), portable, fast, and easy to use. Designed for quick, on-site verifications of mass flow controllers and meters, laminar flow elements, flow meters, and rotameters. Bios International, http://www.drycal.com

CO₂ ANALYZER Wall-mounted infrared analyzer is contained in a water- and dust-tight enclosure with a digital display readout. Sample gas is continuously drawn into the unit through a built-in air pump; a self-draining water trap and a dust filter are also provided. CEA Instruments, http://www.ceainstr.com

IN-LINE FILTERS High-flow filters are molded in polyoxymethylene acetal, with filter frames that are color coded to indicate filter micrometer size. Filters are available in 20-, 65-, 105-, 150-, and 250-mm nylon or polyester screens. Industrial Specialties Manufacturing, http://www.industrialspec.com

CYANIDE ANALYSIS System uses a gas-diffusion ligand-exchange procedure to measure available cyanide or cyanide amenable to chlorination species in 90 seconds. O.I. Analytical, http://www.oico.com
