MARTERIALS: Mott Corp. will be featuring a quick change sparger design that reduces the time and effort it takes to replace sparger elements in bioreactors and fermentors. The quick change sparger is configured with a uniquely designed adapter that allows easy assembly to the mating sparger tip and easy removal for replacement after each batch. This eliminates the need to re-weld the tip or clean the entire assembly. After each batch, a new tip can be installed on the end of the assembly and is ready for steam-in-place operation.Or the sparger tip can be cleaned external to the process utilizing a number of methods including ultrasonic cleaning or detergent and water flush. These spargers are durable and corrosion resistant, and the porosity of the media provides exceptional mass transfer efficiency throughout the tank.
Mott will also display their cartridge filters for vent, steam and gas line applications. These all-metal products provide superior strength, performance, and long life in biopharmaceutical processes. Mott filters are impervious to steam, heat, and most chemical agents and can survive an almost unlimited number of sterilization cycles or can be discarded after each campaign. Mott porous metal performs in high temperatures, corrosive environments, and provides mechanical stability. Cartridges are available with 222 or 226 Code 7 connections and can be purchased separately or with the filter housing. O-rings are also available in a wide variety of materials.
During a teardown of the iPad Air and Microsoft Surface Pro 3 at the Medical Design & Manufacturing Show in Schaumburg, Ill., an engineer showed this "inflammatory" video about the dangers of maliciously mishandling lithium-ion batteries.
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
