Purex has introduced a filtration and recirculation system that addresses the problem of solvent fumes given off by some continuous inkjet printers in the workplace. The system extracts air containing solvent vapor from around the inkjet, filters it and then returns clean air to the workplace. The system utilizes two specially designed delta cowls, one to extract fumes from the print head and the other to extract from the vents on the printer control unit itself. This two-point approach ensures that fumes are not allowed to pollute the work area. The delta cowls are attached to 38 mm flexible stainless-steel arms, which are easy to position yet remain in place once installed. The system uses a specially formulated blend of activated carbon and a chemisorbent media to filter the solvent fumes from the extracted air. Purex filters can be changed in seconds and can usually be changed at the same time as scheduled ink replacement, preventing expensive unplanned downtime. Various controls and sensors have also been incorporated into Purex systems to deliver extra benefits. An ON/OFF control relay, for example, automatically starts/stops the extraction unit when the inkjet printer is switched on/off. Purex units are manufactured from stainless steel and are mounted on castors so they are easy to maneuver. The extraction system works with many different brands of inkjet printers and the Xbase model offers storage for replacement inks and a mounting surface for the inkjet itself.

TREK, Inc. announces the introduction of Model 325 Electrostatic Voltmeter, an ultrasensitive instrument for noncontacting electrostatic voltage measurement and monitoring in applications within high-tech, semiconductor, materials processing, materials science and R&D sectors. The instrument was specifically designed to be used in applications that require highly accurate, low noise, noncontacting measurement of electrostatic voltages from millivolts to +/- 40 V over a wide range of probe-to-surface distances. Features of Model 325 include sensitivity of 1 mV, speed of response less than 3 ms, and accuracy better than 0.05 percent of full scale. The company’s patented low impedance probe sensor assures measurement accuracy that is essentially independent of probe-to-test-surface spacing while eliminating the external environmental effects of high humidity and contamination, such as airborne dust, ions, chemicals and other particulates, on measurement accuracy. Special features of the Model 325 allow tuning the performance of the unit to compensate for specific test conditions. It can be operated as a benchtop unit or in a standard rack (with optional hardware).

Koch Membrane Systems, Inc. (KMS) offers TARGA®-10 Ultrafiltration cartridges for industrial water treatment applications. TARGA-10 Hollow Fiber cartridges have a 10-inch diameter and deliver 60 percent more product water than conventional 8-inch cartridges, resulting in significant cost savings. By using TARGA-10 cartridges, system size is significantly reduced because of the additional flow per cartridge. Requiring 50 percent less floor space, these smaller systems result in substantial savings in building costs and a reduction in the number of skids, lowering shipping and installation costs. Additionally, the larger capacity cartridges reduce the number of connections, thereby improving reliability and further lowering costs. TARGA-10 cartridges feature ultrafiltration membranes and are designed to remove particulates, colloids and larger molecular weight components. The cartridges function as an ideal pretreatment step for spiral RO membranes and have demonstrated the ability to reduce turbidity to less than 0.1 NTU, and SDI to between 1.0 and 3.0. The cartridges utilize KMS polysulfone membrane material, which can handle a broad pH range, from 1.5 to 13, and can tolerate up to 200 ppm of chlorine. KMS also offers KOCHKLEEN® Membrane Cleaners to help prolong membrane life, enhance membrane performance and reduce cleaning cycle time.

As a result, the system is capable of processing a wide variety of fluids ranging from simple oil-in-water emulsions to highly immiscible solid-in-liquid suspensions. Process pressures are highly variable and reproducible, ranging from 3,000 psi to 23,000 psi. The processor features a flow rate range of 250 to 600 mL/min. It’s designed for clean-in-place procedures, which prevents the risk of sample cross-contamination. Optional equipment includes a sanitary-finish diaphragm pressure transducer with reader and a large-capacity reservoir and adapter.
Patented ultraclean container
Novapak Corporation has recently introduced a new, patented, 4-liter, ultraclean, pressure-bottom container intended for packaging of solvents, acids and other ultrapure chemicals utilized in electronics manufacturing, laboratory testing and other contamination-sensitive applications. The pressure bottom is designed to resist bulging, distortion and loss of container stability associated with chemicals that build internal pressures up to 35 psi. The HDPE containers are blow-molded, using nitrogen as the blowing gas, and then capped to ensure cleanliness for particulate-sensitive chemicals and processes. In addition, the containers can be fluorinated in-line using a mixture of fluorine and nitrogen as the blowing gas, chemically modifying all interior surfaces of the molten HDPE container and creating an inner barrier that resists permeation by non-polar (oil-based) solvents. The solid strap handle provides a means to hold and pour the bottles securely, while eliminating the potential source of particulate contamination of hollow handle designs. The container is 13.645 inches tall, 6.030 inches in diameter, has a 38/439 neck finish and weighs 210 grams.
