When choosing a vacuum pump for their laboratory, many people find vacuum technology a bit confusing. Rather than wrestle with the details of vacuum pump specifications and how they relate to the application at hand, the temptation may be to choose the pump they had before (even though it may reflect aging technology), look for the [...]
In certain industries, successful research, product development or manufacturing depends on the maintenance of a contaminant-free environment. Work on pharmaceuticals, medical devices and electronics, for example, may be compromised by particulates or airborne microbes. To protect these critical processes, cleanrooms are used to control airflows to achieve extremely low particulate loads. Operating the equipment needed to [...]
In our last blog entry, we reviewed the challenges presented by using uncontrolled vacuum in the lab, and took a look at manual options for vacuum control. In this note, we’ll examine options for electronic vacuum control. Electronic vacuum control requires both detection and a control technique. The detection is provided by an integral vacuum gauge [...]
Success in a laboratory relies in large part on precision. Whether setting a temperature, mixing a solution or taking a measurement, control of the process determines the consistency of results. Even so, lab operators who require vacuum for their applications often default to simply "turning on" the vacuum, allowing the pump to operate at maximum capacity. [...]
Lab vacuum pumps are exposed to all kinds of challenging substances: acid vapors, organic solvent vapors, water, particulates. It’s not surprising that a product designed to create suction would have to contend with all of these materials, but does it have to be such a headache? In prior blog entries (Vacuum Pump Service, Parts 1 & [...]
Lab vacuum pumps are exposed to all kinds of challenging substances: acid vapors, organic solvent vapors, water, particulates. It’s not surprising that a product designed to create suction would have to contend with all of these materials, but does it have to be such a headache? The answer is “No.” In our previous blog entry (Vacuum [...]
Lab vacuum pumps are exposed to all kinds of challenging substances: acid vapors, organic solvent vapors, water, particulates. It’s not surprising that a product designed to create suction would have to contend with all of these materials, but does it have to be such a headache? The answer is “No,” and you can greatly reduce the [...]
Vacuum pumps play a role in many lab applications, and sometimes it helps to automatically control this piece of equipment. “Any application where someone is trying to separate components of a mixture in a precise and repeatable way is a good candidate for an automatically controlled pump,” says Scott Leahy, director of technical marketing at [...]
Do you need a vacuum pump, sir? How ‘bout one that doesn’t bump, sir? VARIO® from VACUUBRAND Doesn’t need a guiding hand. We’ve got many other choices That respond when users’ voices Shout “I want that vacuum quiet!” “Put that footprint on a diet!” “Make it chemical resistant!” (The scientists are so insistent!) Flow-paths made [...]
