Lab Vacuum for Chemists

Imagine 1.5 Torr at every vacuum inlet, with no interference from nearby labs that is whisper quiet. 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.

Chemistry Laboratory Applications

Rotary Evaporation

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.

Lab Vacuum Oven

VACUU•LAN® lab vacuum networks provide vacuum ovens with the necessary depth of vacuum, and also the flow rate needed to completely dry samples in an efficient amount of time. Since expansion of liquid to vapor phase greatly increases total volume, flow rates for lab vacuum application become increasingly more critical for even modest starting sample volumes. These lab vacuum systems can also supply much deeper levels of vacuum than traditional central vacuum system so heating requirements from the oven are greatly reduced providing an overall energy savings for the lab. With VARIO™ control, vacuum ovens are able to maintain set vacuum level to maintain experimental conditions in sample handling. All this without the need for benchtop pumping systems when incorporated into the lab’s VACUU•LAN® network.



VACUU•LAN® lab vacuum networks can also provide variable controlled lab vacuum supply to concentrators. With VARIO™ control the vacuum supplied can be dialed in for dealing with small sample volumes in your concentrators to reduce chances of boiling out samples.



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 and 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.
Filtration Setup
VACUU•LAN® local vacuum networks allow for flexibility of access point and performance of their laboratory vacuum needs. These systems eliminate the need for dedicated individual pumps that can take up valuable bench space, while providing a much quieter working environment for the bench scientist. Automated controls ensure optimal performance during experiments, and the modular design allows users to reconfigure and increase capacity of their vacuum system with relative ease.
