Operating at the heart of production facilities or experimental set-ups, pumps need to be precise, reliable, low in maintenance and durable. Although the range of available pumps is huge, the choice of products often becomes much smaller when the specific requirements of the intended application are taken into account. To quickly find the ideal pump for your needs, click “Products Pumps” below, and then use any of the various options to narrow down the list.

Pfeiffer Vacuum celebrated the expansion of its facility in Wuxi, China on October 23 with a grand opening ceremony. Double its original size, the new, expanded facility marks a significant milestone in Pfeiffer Vacuum’s development in China, as it allows the company to better respond to local custo more
Driven by natural or artificial sunlight, a novel “microtube pump” transports water droplets over long distances. As reported by Chinese researchers in the Journal Angewandte Chemie, the pump consists of a tube whose properties can be changed asymmetrically through irradiation. This results in capil more
Some 9 months before the start there are unmistakable signs that ACHEMA 2018 will be a crowd-puller. More than 2700 exhibitors from all around the globe have already booked a stand at this leading show for the process industries in Frankfurt am Main. From 11 to 15 June 2018 they will be showcasing t more

Among the plethora of photochromes reported so far, azobenzene has been proven to be the most suitable photoswitch for molecular systems and materials, due to its highly efficient and clean E–Z photoisomerization. Here we report two ammonium-based molecular axles bearing one or two p-cyanoazobenzene more
While the microfluidic device itself may be small, often the equipment required to control fluidics in the chip unit is large e.g. pumps, valves and mixing units, which can severely limit practical use and functional scalability. In addition, components associated with fluidic control of the device, more
