The new micro dosing unit Type 7615 is a high-precision diaphragm pump for exact dosing in the microliter range. Comprised of three valves, the dosing unit doses 5 µL in one stroke with an accuracy of ±2%. The maximum flowrate…
The portable, non-metallic Flex-I-Liner rotary peristaltic pump evacuates drums and totes containing acids, caustics, salts, chlorides and reagent-grade chemicals without corrosion of the pump or contamination of the fluid. The self-priming design of the Flex-I-Liner has no seals to leak…
Cationic polymers have been used in the petroleum industry as shale-control agents, demulsifiers, blocking agents, and filtrate reducers for drilling fluids, but process complexity and high cost have limited their application. Now researchers from Zhejiang Normal University (Jinhua; www.zjnu.edu.cn) and…
A photocatalyst that reduces CO2 into carbon monoxide is being commercialized by Tokyo Chemical Industry Co. (Tokyo, Japan; www.tcichemicals.com/en/jp/index.html). Developed by Osamu Ishitani and his research group at Tokyo Institute of Technology (TiTech; Japan; www.chemistry.titech.ac.jp/~ishitani/index-jp.htm), the catalyst is a step…
A research group at Rice University (Houston; www.rice.edu) has developed a method for vaporizing water into steam using sunlight-illuminated nanoparticles, with only a small fraction of the energy heating the fluid. Sub-wavelength metal or carbon particles are intense absorbers of…
Under an ARPA contract Gas Technology Institute (GTI, Des Plaines, Ill.; www.gastechnology.org) is developing a process to convert natural gas directly into methanol and hydrogen. The process is much simpler and more efficient than the conventional high-temperature and capital-intensive steam-reforming…
An Indian team from the Institute of Minerals & Materials Technology (www.immt.res.in), and Utkal University (both Bhubaneswar, Orissa, India; www.utkal-university.org) has achieved significant improvement in the recovery of nickel from lateritic ore by using oxalic acid produced by the fungus…
The Titan Series TSG valve is designed to meet the most demanding applications involving heavy-duty abrasive materials, such as sand, gravel, coal, whole grains, metal powders or minerals. The TSG Valve handles dry material in gravity-flow applications where positive material…
The new DEPA Nopped S Diaphragm features an innovative “nopped” surface, designed to create advantageous flow conditions emulating the effect of golf-ball dimples. The use of Santoprene as its core material — a substance uniting elastomer (EPDM) and polypropylene —…
A new tubing solution for use in chemical dispensing applications is now available in Europe. The Tygon 2375 Ultra Chemical Resistant Tubing replaces the widely used Tygon 2075 line, providing an improved pressure rating, “outstanding” chemical resistance and “superior” flexibility,…
