The Model 4042™ Spill Containment Scale and Model 4042WB™ Secondary Spill Containment Scale™ are designed for weighing chemicals in tanks, drums, intermediate bulk containers, and tote bins. They weigh only the chemical dispensed into the water treatment system. If there is a chemical spill, the weight is still on the scale and does not read as though it has been dispensed into the system. The scales also have four load cells that are completely sealed in PVC and vinyl plastic enclosures, which means that they are protected from spilled chemicals and that the chemical containers do not have to be centered, balanced, or leveled. Scaletron Industries Ltd. (Plumstead, Pa.).
The SpillSafe™ drum scale monitors the amount of chemical used and the quantity remaining while also providing security against uncontained chemical spills. The drum scale allows the system to detect a leak, provides early warning to the operator, and complies with local regulations by containing 120% of the drum capacity. Force Flow (Concord, Calif.).
The EcoThermTM Model IC35 Series peltier-driven chilling–heating, heavy-duty dry baths are capable of handling a large variety of sample blocks. Units are fully programmable and can store five 10-step programs in memory. Each program can be set to repeat automatically from 1 to 99 times. The IC35 (–10°C to 100°C) and IC35XT (–20°C to 100°C) can freeze, chill, or heat samples in a variety of sample blocks that can hold 0.5-mL to 50-mL centrifuge tubes, test tubes, vials, assay plates, and round-bottom flasks. Torrey Pines Scientific Inc. (San Marco, Calif.).
The AQUACOUNTER® COM-300A Automatic Titrator performs pH, acid–base, complexometric, redox, Karl Fischer, photometric, nonaqueous titrations, and ion-selective electrode measurements. It has more than 30 files of built-in method memory. JM Science (Grand Island, N.Y.).
Designed for larger piping systems with flow rates as high as 40,000 gal/min, the Model 510 Simplex Basket Strainers help protect expensive piping system components from damage caused by particulate matter in the system flow. The use of four strainer baskets per unit, rather than one, helps keep baskets smaller and easy to remove and clean. Eaton Filtration LLC (Elizabeth, N.J.).
UV Lamp Ballast System
This modular ballast system is suitable for lamps from 40 to 330W. The system is adaptable to all three-phase networks worldwide, has no reactive current, and has low electromagnetic disturbance and low power and heat loss. UV-Technik (Hampstead, N.H.).
Vibration Data Logger
The OM-CP-SVR101 Spectral Vibration Recorder (SVR) is a self-contained device engineered to record acceleration data for spectral analysis of vibration and peaks. The device will record and time-tag 3-axis vibrations and peaks to provide a history of shock and vibration conditions. It also records temperature once every sample period. The OM-CP-SVR101 measures and computes real-time spectral data. To make efficient use of memory, it only takes data when the (user-preset) trigger level is exceeded. Omega Engineering Inc. (Stamford, Conn.).
Confined-Space Work Tents
Offered in three sizes, the Deluxe Work Tent features quick setup with pop-up framing and an attached roll-up flap for compact storage and easy transport. The tent is built to withstand wind, rain, and snow, utilizing bolted frame rods for increased stability. The Economy Work Tent is constructed from water-resistant, flame-retardant nylon and springs open from backpack into full size in seconds. The open bottom allows protection while working over manhole covers or excavation sites. To protect against rain and other weather elements, both tents feature a pitched roof, which provides extra headroom. Allegro Industries (Garden Grove, Calif.).
The new Dual Layer Color-Coded PEEK Tubing eliminates any concern that a critical sample stream could be contaminated by pigments used to color-code the tubing. It looks like any other color-coded tubing, but the pigmented layer surrounds a separate but integrally bonded inner layer of natural PEEK. The pressure performance is equivalent to single-layer tubing. Valco Instruments (Houston).
The 4JSCM, a 4-in. high-efficiency dry-priming pump, is a powerful, lightweight, compact pump that handles solids up to 3 in. With a flow capacity of 1450 gal/min and a shutoff head of 130 ft, this pump is suitable for bypass and construction dewatering applications. Thompson Pump & Manufacturing (Port Orange, Fla.).
LOFCLEARTM Series 100 Filter Bags are designed to make high-efficiency liquid filtration viable in applications where standard filter bags currently are used due to cost constraints. The bag’s design includes a polypropylene prefilter layer, a meltblown polypropylene microfiber final filter layer, and a polypropylene outer migration barrier layer. Eaton Filtration (Elizabeth, N.J.).
This ST line of resilient seated butterfly valves offers high flow coefficients, ISO top mounting, a one-piece body with self-centering disc, and a large selection of direct mount actuators and gear operators. Manual valves with limit switches are also available for applications that do not require automation but do require feedback to a programmable logic controller or network bus system. Assured Automation (Clark, N.J.).
The Ultra Mag® Wastewater Flow Meter is designed to provide superior measurement accuracy in effluent applications, require minimal maintenance, and offer a long life of trouble-free service at a low life-cycle cost. With its noninvasive, no-moving-parts flow-sensing technology, it delivers flow measurement accuracy of +0.5% in water effluent with repeatability of +0.05%. The meter is manufactured with type 316 stainless steel, and its electrodes feature a bullet-shaped self-cleaning design. McCrometer (Hemet, Calif.).
This explosionproof polymer makedown system for preparation, activation, and injection of liquid polymers in water and wastewater treatment applications can produce dilute solution (0.1% to 2.0%) at capacities from 20 gal/h to 3000 gal/h of total makedown solution. It features all stainless steel construction and uses the patented Gatlin Mixer for mechanical mixing and blending of polymer material. The Gatlin is a motorized mixing chamber that segments the polymer into ultrathin film for maximum activation. The system does not require booster pumps, and materials are mixed and blended without blades. Fluid Dynamics Inc. (Boulder, Colo.).
The Macro Volume Pipettor with 10-mL tip is designed to handle large volumes of liquid accurately and safely. It features excellent chemical resistance and is compatible with most liquids, including chloroform. Safe Cone filters installed into the tip cone can minimize the risk of contamination. Biohit (Neptune, N.J.).
