Dual-shaft change-can mixers handle viscous products
Equipped with an anchor and a high-speed disperser, the CDA Dual-Shaft mixers cater to products with viscosities up to several hundred thousand centipoise. Each agitator is independently driven by an explosion-proof motor to enable its use for variable-speed operation. Stocked units are available in 2-, 10-, 50- and 100-gal sizes (change-can models are available in 2 to 1,000 gal) and include Type 304 stainless steel wetted parts, vacuum construction, and air-oil hydraulic lifts to raise and lower the agitators. Thermocouples, jackets for heating or cooling, and a variety of discharge valves are optional features. Units are available for sale or rental.

Reach into this incubator for cell cultures
The ergonomically designed Reach-In CO2 incubator provides the ideal environment for small-to-large-scale, high-volume cell culture. This 30-ft2 chamber provides precise control of temperature, relative humidity, and CO2, and offers the latest technology in sensors, including infrared (IR) CO2. Control and uniformity parameters are said to rival any conventional benchtop incubator, providing maximum culturing space in a minimal footprint. This system controls humidity by monitoring and injecting water, thereby eliminating the need for humidity pans and the potential for contamination and corrosion caused by standing water.

Factory-floor traffic and harsh chemicals won’t crack or corrode these surface coatings
Steel-It anti-rust stainless steel coatings create a metallic barrier that helps prevent corrosive attack from chemicals, solvents, detergents, salt spray and power washing. Suitable for machinery and conveyors where all-stainless steel construction is impractical, these single-component paints exhibit 2H pencil hardness, so they resist chipping and scratching from tools and carts. USDA-approved, they can be applied by brush, roller or spray systems, yielding a smooth metallic-gray finish that can last up to 10 years, depending on the environment.

Platinum temperature sensors are small, but fast
Ceramic wire-wound platinum sensors are typically used in applications requiring a wide operating temperature range and high measurement stability. Types KN1008 and KN3005, with diameters of 0.8 mm and 0.5 mm, can be used in applications previously off-limits to wire-wound elements due to size constraints. Also broadening its applications range is a design that complies with the IEC 60751 specification. One of the sensor’s most notable features is its small diameter, which enables response times of less than 0.2 s.

For water analysis, here’s a waterproof photometer
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 sample is simply placed in the adaptive cell holder, which, with the press of a button, automatically adjusts to any round tube size. The 7100 features automatic light wavelength selection for each of the pre-programmed test methods. It has easy-to-navigate menus, and the software also remembers the most recent tests, making it even quicker to use the next time. Sealed to IP67, the unit runs on standard AB batteries. The photometer is available in two kits, a standard kit and an engineer’s kit designed specifically for mobile water service engineers. Each comes with a carrying case and room to store the required reagents.

A self-contained analyzer detects with parts-per-trillion sensitivity
Designed for OEM end-user products, the microAnalyzer combines Sionex’s patented microDMx technology with a miniaturized gas chromatographic module, enabling sample collection, sample separation, and detection and identification of compounds with selectivity and sensitivity down to parts-per-trillion levels. Analysis is based on the ionic compounds’ differential mobilities through the sensor chip, which are a function of charge, mass and cross-sectional area. By applying an RF or DC field to the sensor chip, one can make the filter select a chosen ion or collection of ions. The device is ideal for process control, air-, fenceline-, and environmental monitoring, and other applications.

Measure dissolved sulfides in water with this noncontact device
Sulfide concentrations in water are typically measured using analyzers that employ selective ion electrodes (SIE) for sensing. While providing adequate sensitivity, poor-quality samples make fouling of the analytical system a major concern. The A15/81 system overcomes this problem by employing a polagraphic H2S gas sensor that never comes into contact with the sample; only the gas stream containing the stripped H2S reaches the sensor. The device provides extremely high measurement sensitivity down to low parts-per-billion levels.

Use these flow sensors to measure low flowrates
Designed as an electronic alternative to ball-and-tube rotameters, Models 104 and 107 Liquid Flo-Sensors precisely measure flowrates as low as 13 mL/min. Stainless steel construction is compatible with virtually any chemical, including many solvents and organic compounds. Linearity of ±1.0% (full scale) and repeatability of ±0.2% (full scale) provide accurate readings for critical applications. An analog 0-5 V d.c. output and pulse output are both provided standard; 4–20 mA outputs and an integrated display are optional.

Now you can digitally program this controller
This all-digital electric stroke controller regulates the flowrate of metering pumps in response to a 4-20-mA DC control signal. The unit also accepts 0–5 Vdc and 0–10 Vdc analog control signals or can be operated from incremental dry-contact closures. The new actuator has the same housing structure as its analog predecessor, allowing for easy upgrade of older pumps. It improves on the older design by simplifying configuration and calibration through the use of color-coded push buttons, LEDs and a single adjustment knob. Both customer calibration and factory-default settings are retained in the device’s memory, even during power failure.

Double-eccentric butterfly valves are inherently safe
Designed for industrial, potable and wastewater treatment systems, the Type 567/568 butterfly valve series features a double-eccentric-disk design typically found only in high-end metallic configurations. This double eccentricity reduces seal friction and wear, resulting in longer service life, minimal maintenance and better protection against pressure surges. It also lowers the torque required to operate the valve, easing manual operation and allowing the use of smaller, less expensive actuators. The 567/568 series feature a modular design ranging in size from 2 in. to 8 in., with either a glass-filled polypropylene wafer body (Type 567), or an epoxy-coated iron lug body (Type 568). The inner body, disks, and bearings are available in PVC, polypropylene and polyvinylidene fluoride. The lockable ergonomic lever enhances worker safety via a 5-deg ratchet setting that ensures precise positioning of the lever and eliminates incidental movement due to accidental bumping of the handle. Other safety features include an integrated electric position indicator in the mounting flange that shows whether the valve is open or closed. An index plate clearly indicates the angle opening in degrees.

A microemulsion to enhance soil decontamination
A new in-situ technology, HRC Advanced (HRC-A), time-releases a combination of highly efficient lactic and fatty acids that enhance the near-, mid- and long-term biodegradation of many chlorinated and other contaminants, including industrial degreasers, chlorofluorocarbons, carbon tetrachloride, methylene chloride and a variety of pesticides, explosives and dyes. HRC-A is shipped as a concentrate and mixed onsite with three parts warm water to form a micellular microemulsion, which has greater soil-coverage capacity than comparable products. As the solution is pumped throughout an aquifer, it slowly releases lactic acid, which is fermented by naturally occurring bacteria. The hydrogen that is released accelerates the biodegradation processes and reduction of the target contaminants to harmless end-products.
