  High-flow cartridges

High-flow All-Poly Cartridges from Harmsco Filtration Products suit laboratory applications where absolute rated filtration is needed. They include up to 75 square feet of filtration media and are constructed with 100 percent polypropylene materials for efficiency ratings to 99.98 percent. The pleated polypropylene media provides high flow rates and low initial pressure drop. The pleated surface increases loading capacity for long filter life and high particle removal. The double O-ring end cap, center tube and media are thermally bonded as one integral component. 800/327-3248;

  Unitized fume hood

The Aire-Stream fume hood from HEMCO is made entirely of chemical-resistant, flame-retardant, non-metallic composite resin materials and has unitized construction that needs no screws, bolts, rivets or metallic hardware to assemble. The fume chamber is molded into one seamless piece with all corners curved for easy cleaning and light reflectivity. It is UL 1805 certified and is offered in 48-, 60-, 72- and 96-inch widths in constant air volume or restricted bypass models. It has a 36-inch-high extended-view height, slotted rear VaraFlow baffle system, aerodynamic sash lift with perforated air-sweep, and molded-in belled outlet collar for reduced airflow resistance. 816/796-2900;

  Microbiological testing system

The ENDETEC TECTA B16 from Kruger USA is an automated microbiological testing system that provides fast laboratory-grade results on site. It uses proven enzyme/fluorescence chemistry with a Polymer Partition process to test for E. coli and total coliforms in water. With full automation and continuous monitoring of the test analysis and results interpretation, the system provides an objective result that can be sent to a cellphone or laptop for notification as soon as a contamination event is identified. 919/677-8310;

  Calibration, maintenance and training program

The LabLite CMT program can schedule and track the calibration and maintenance required on every item in a plant, lab or company. It can track who was assigned, when work started and ended, emergency repairs, the time an item is down, and the cost of these events. Technicians can add documents and images for each item. The system records service and warranty information and tracks the equipment location and responsible party. It schedules and tracks training events and automatically updates individual training records. 888/954-5483;

  Sampling system

The Simpler Sampler automatic duckbill sampling system from Markland Specialty Engineering automates the composite sampling required to monitor for process effectiveness and environmental regulatory compliance in water treatment. It uses compressed air to move samples up high lifts (more than 79 feet) and over long runs (98 feet). The electronic controller can be located far from the sample site. Sampling can be determined by time or flow, and manual samples can be called in at any time without affecting the normal sampling interval. The rubber duckbill closes down and expels any large particles in a self-cleaning action. The sampler head is available in aluminum, stainless steel and PVC. 855/873-7791;

  Managed SCADA system

The managed SCADA system from Mission Communications offers reports that record chlorine, pH, pressure, turbidity, temperature, dissolved oxygen, fluoride and other variables. Variables can be recorded in real time and alarms dispatched at various setpoints. Reports can be used to submit daily and monthly minimum and maximum values for compliance. Reports are accessible from any Web-enabled device. The trending data can be viewed in spreadsheet, graph or chart-recorder format. 877/993-1911;

  Negative air pressure fume hood
