Filtration Series diaphragm pumps promote
"green" operations by performing cleanly without pump oil, conserving water by
eliminating water aspirators, supplying consistent vacuum levels and
eliminating any potential for solvent-contaminated waste generated by oil-type
pumps and water aspirators. KNF Laboport pumps have multi-port valves to
increase performance and can tolerate occasional liquid condensate drawn into
the system without incurring damage. Pump heads integrate corrosion-resistant
wetted parts and the heavy-duty, all ball-bearing motor is lubricated for life.
The pumps can achieve flow rates from 5.5 L/min to 37 L/min and vacuum from 15
Torr (29.3 in. Hg) to 120 Torr (25.2 in. Hg), depending on version. Pumps are
compact, weigh between 1.9 to 4.0 kg and an optional dampened vacuum gauge and
vacuum regulator valve assembly provide smooth vacuum control.
KNF Laboport pumps provide solutions for
flask filtration, vacuum blotting, vacuum manifold and vacuum desiccation and
are alternatives to oil-lubricated pumps, water aspirators, piston pumps, and
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.
Microchip recently released the 3D TouchPad, the first USB PC Peripheral device that couples 2D multi-touch input with 3D air gesture technology. The company seeks the help of developers to further enhance the capabilities of the technology.
To give engineers a better idea of the range of resins and polymers available as alternatives to other materials, this Technology Roundup presents several articles on engineering plastics that can do the job.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
