Imagine 1.5 Torr at every vacuum inlet, with no interference from nearby labs. And consider the savings in equipment costs and bench space of getting “real vacuum” from your vacuum network instead of individual pumps. That’s why scientists prefer VACUU•LAN® vacuum! Need electronic control for critical applications? Just add VACUUBRAND controllers to VACUU•LAN® network ports and you have electronic vacuum control as part of your network without dedicated pumps at every station. And if you need the advanced control of VACUUBRAND® VARIO™ pumps for your critical research, you place these speed-controlled pumps where needed without duplicating vacuum capacity from a central system.
While VACUUBRAND supplies vacuum for multiple users with our VACUU•LAN® networks, if you need a single pump, we can help you find the right one with our application-based Selection Guide.
Rotary evaporation procedures are given exceptional control when rotovap systems are tied to VACUU•LAN® networks. With VARIO™ control, experiments can be carried out with no hysteresis effect allowing chemists to automatically control the boiling points of their solvents and greatly limiting any bumping effects on their precious samples. All this without the need for benchtop pumping systems when incorporated into the lab’s VACUU•LAN® network.
Fluid Aspiration and Biocontainment
Fluid aspiration within a biocontainment suite is a critical component to the lab work performed within the lab space. Since the objective is containment, by definition, a dry vacuum pump within a VACUU•LAN® network can be installed within the controlled space supplying as few as 2 or as many as 20 workstations. Each workstation is equipped with 0.2 micron sterile filters to keep bio-aerosols out of the vacuum lines. Since all flow within the vacuum network moves towards the single vacuum pump, control of exhaust is much simpler than with multiple pumps; the single exhaust line leaves the contained space through the HEPA filters that manage all airflow in the containment space. The location of the pump within the contained space, and the HEPA-filtered exhaust, provide extra protection against aerosol release beyond that offered by the sterile filters at the workstations. The single pump generates only about as much heat as a couple of light bulbs, minimizing heat gain that needs to be managed for energy efficiency and comfort.
In the cleanroom environment, the objective is to minimize the release of contaminating particulates. In this instance, the network pump would be installed (and exhausted) outside of the controlled space, so no particulates that may be drawn into the vacuum system are recirculated into the controlled environment. The network is plumbed to the interior, where individual workstations may be optionally equipped with electronic controls that can provide unique, programmable vacuum conditions to each workstation. And once again, the single pump saves precious space within the expensive facility, without sacrificing the control that might otherwise call for a dedicated pump inside the cleanroom.
Filtration, Aspiration, and Solid Phase Extraction
VACUU·LAN® local vacuum networks are ideal for suction applications like the fluid aspiration used in cell culture labs, solid phase extraction used for sample preparation, as well as for routine filtration. These operations need only a modest depth of vacuum, but exhibit highly variable flow characteristics. When operations begin, the devices are filled with liquids, and vacuum levels insufficient to cause evaporation, vapor flow and pumping speed requirements are close to zero. When a filtration or SPE operation “breaks through,” or an aspiration application runs out of liquid, however, the in-rush of free air causes pressure spikes (sudden loss of vacuum capacity) that can disrupt nearby applications. VACUU·LAN® technology protects the adjacent applications without the large pumps and ballast tanks needed in central vacuum or uncontrolled lab vacuum manifolds.
