Vacuum pumps are an essential piece of equipment and used in a wide variety of processes in most laboratories. However, despite numerous advances over the past 70 years, many industry professionals still believe that vacuum technology has not progressed, and that there is no benefit from updating a laboratory pump.<\/p>\n

The Future For Laboratory Vacuum Pumps<\/strong><\/p>\n

Innovation in vacuum technology is currently being driven by the many diverse manufacturing and research processes that rely on vacuum systems, particularly the manufacture of semiconductors. With increasing demand for reliable and efficient vacuum techniques, the rate of innovation looks likely to increase in the immediate future.<\/p>\n

Experts predict that vacuum pumps of the future will offer greater reliability and be able to operate for longer periods of time before maintenance is required. Laboratory pumps are also expected to be smaller, more efficient, and generate less heat, noise and vibration. It is likely that they will also better resist corrosion and be easier to clean and repair.<\/p>\n

Technological developments are likely to include higher shaft speeds and innovation in pumping mechanisms for improved performance. Vacuum pumps are also expected to incorporate novel materials and improved design to further improve performance and reduce operating costs.<\/p>\n
