A replacement for this instrument maker’s 5000 photometer, the 7100 enables advanced instrumental analysis of an extensive range of water tests. Portable and waterproof, the photometer uses light to measure color changes in water samples treated with a reagent. It is accurate to ±0.005 at 0.3 absorbency units (au) and resolution is 0.001au, avoiding the inaccurate results that a comparator color chart may give due to variations in operator eyesight or lighting conditions.

The new Liqui-Flux ultrafiltration module has a total membrane area of 75 m2. The pressure-driven module is said to be one of the largest ultrafiltration modules of its kind. The large surface area within the membrane bundle structure allows individual modules to have a smaller system footprint and lower capital costs than other systems with comparable throughput. At the heart of the Liqui-Flux module is the company’s UltraPES polyethersulfone hollow-fiber membrane. The membrane has a distinct three-layer structure to ensure maximum permeability and reliability.

Air-Miser MSP-AM Series multi-stage venturi vacuum pumps use low air pressure yet provide performance comparable to that of a higher-pressure system. Because of their internal design, they require only 45 psi (3.1 bar) of air pressure, which is about half of what is needed in conventional venturi-style vacuum pumps. They are made from anodized aluminum with brass nozzles, and models are available to handle process flowrates of 0.06–0.64 standard ft3/min. They measure 3.78 in. long by 1.26 in. wide by 0.98 in. high, and include a 2.76-in. tall by 1.0-wide muffler.

A tapered cone design allows these variable-volume pipettes to use tips from many different manufacturers. The pipettes are available in six sizes: 0.5–10 µL, 2–20 µL, 10–100 µL, 20–200 µL, 100–1,000 µL and 1–5 mL. Volume is adjusted by turning a button. A large display window makes it easy for the user to select the correct volume, and reduces the risk of accidental volume changes during pipetting. An ergonomic design that requires low plunger force offers protection against repetitive stress injuries. The pipettes can be sterilized in an autoclave to prevent cross-contamination.

Made from chemically resistant polytetrafluoroethylene (PTFE) and glass, the Asia syringe pump is rated to 20 bar (300 psi). This compact (23-cm wide) module offers two independent continuous-flow channels, each with an integrated pressure sensor and a flowrate range of 1.0 µL to 10 mL/min. Replacement of component valves, syringes or pressure sensors is quick and easy, requiring no tools. Flowrate and volume can be controlled using the intuitive front panel, or by means of the Asia PC software.

The SaniQuip sanitary mixer is suitable for sanitary, pharmaceutical, biotech, cosmetic, and food applications. Its lightweight motor provides continuous speed control, with power ratings for various models ranging from less than 1 hp to 5 hp with constant torque, and variable speeds between 100 and 2,000 rpm. The mixer features an integral digital tachometer and a high-polish finish on in-tank wetted parts. Its design is a compact open pedestal, and has integral tri-clamp tank mounting. The mixer can be used in tank volumes from 50 L to 20,000 L.

This high-speed inline wet mixer processes material through a patented modular shear-action mixing head that forces all product through several stages of high-speed rotors and stators to achieve a consistent and repeatable finished product. It is easily configured to match precise viscosity requirements, and features a modular, all-stainless-steel construction that incorporates from 1 to 12 shear-action zones. It can handle viscosities above 100 cP at flowrates from 0.5 to 300 gal/min, as well as applications requiring dispersion down to 1 µm.

These heavy-duty side-entry mixers are designed with easy access to all bearings, seals, grease fittings and lube ports. They can be maintained using off-the-shelf commercial components to minimize costs and downtime. They feature steel housings, rigid motor mounts, oversized shafting, Dodge type E piloted dual-tapered roller bearings, belt drives with QD-style bushings, and HYFLO 4-blade impellers. Seal materials and construction materials are customizable. The mixers are available in sizes ranging from 1.5–300-hp motors, 1.5–6-in.-dia. shafts, and 12–48-in. impellers.

These two-stage tandem rotary-screw compressors provide excellent full-load efficiency, and have demonstrated a 2-yr payback in energy savings over single-stage compressors. The TS-20, TS-32 and TS-32S models have constant-speed drives and capacities of 500–3,000 actual ft3/min (acfm). The V-200TS and V-320TS variable-speed-drive models have a capacity range of 495–2,310 acfm. All models in both series have pressure capacities ranging from 100 to 175 psig, and use the manufacturer’s spiral valve technology to match pressure and capacity with system demand.

The Driflex oil-conditioning system completely removes free, emulsified and dissolved water from a wide variety of industrial and mobile lubrication and hydraulic systems. Dirt and water contamination is responsible for 70–80% of lubricated-equipment wear and failures. This system reduces water concentration and improves particulate-filtration effectiveness to optimize oil condition and minimize equipment wear, reducing maintenance expenses and costly downtime.
