Vacuum technology

VACUU•LAN® lab vacuum networks are the high-performance, modular alternative to other lab- and building-wide vacuum systems. Because of their performance, sustainability, and economic advantages, these networks have become the preferred choice of leading architecture and engineering firms, educational institutions, research organizations and industrial firms.
The Concept
• A single pump supports work groups of up to 20-25 simultaneous users
• Provides vacuum as deep as 2 mbar (1.5 torr or 29.86 in Hg) at the point of use
• Chemical-resistant tubing and fittings prevent system degradation due to corrosion
• Specially-designed vacuum fixtures ensure deep, stable vacuum and isolate users from one another
• Perfect for renovations, retrofits, and new construction
Benefits
• Deep, stable vacuum – 1.5 torr (2 mbar) at the point of use means you can eliminate many individual pumps
• Isolated – minimizes interference and cross-contamination risk among users
• Modular and scalable – suitable for any size project, from a single lab bench to an entire lab building; no need to overbuild ‘just in case’
• Adaptable – upgrade, move, or expand systems easily as needed
• Sustainable – reduces power consumption by up to 70-90% vs. central vacuum systems; eliminates water consumption and contamination caused by use of water jet aspirators
• Economical – low upfront cost per user through ‘right-sized’ installation; microscopic operating costs due to ultra-low maintenance and power consumption

The VACUU•SELECT complete controller provides enhanced process efficiency to applications supported by a vacuum source such as a basic pump or a powerful vacuum network. The VACUU•SELECT controller has you covered. Use manual set-point-control for simple processes, run pre-defined applications at the touch of a button, or create your own application with simple drag-and-drop editing. The controller is available as a benchtop unit, ready for mounting on lab scaffolding, or as a built-in version for lab casework. The integrated controller includes the VACUU•SELECT vacuum controller, a check valve, and a chemical-resistant solenoid isolation valve. The ceramic vacuum sensor and venting valve are built right into the body of the VACUU•SELECT controller. The compact unit is easy to install and setup. With its intuitive, application-based interface, the controller offers predefined vacuum processes for all common laboratory applications. In the case of solvent evaporation, it detects the boiling pressure and then holds the pressure level stable using two-point control.
Performance features
• supplied complete and ready for use, including integrated valve and common hose connections
• predefined vacuum applications and automatic boiling point detection saves time
• simple setup - connect VACUU•SELECT in-line between pump and vacuum application
• integrated vent valve allows inert gas connection
• integrated check valve minimizes interaction with other applications on the same vacuum supply

Screw pump for aggressive gases and vapors
The dry screw pump VACUU•PURE® 10C reliably delivers the benefits of oil-free vacuum technology in the pressure range of 10-3 mbar. The new vacuum pump combines three important benefits for the user: 100% oil-free, chemically resistant, and no wear parts.
VACUU•PURE 10C is ideally suited for clean processes and the production of pure products. The screw pump is especially designed for processes in the vacuum range down to 10-3 mbar, however unlike other fine vacuum technologies it can be used across the entire pressure range from atmospheric pressure to its ultimate vacuum. At the same time, aggressive gases and vapors can be pumped without any worries because of the high chemical resistance. The use of a cold trap is no longer necessary in the majority of applications.
VACUU•PURE easily handles high vapor loads through its extraordinary condensate compatibility. Thanks to this capability, a gas ballast is unnecessary, avoiding associated disadvantages like the reduction in pumping speed and an increase in noise levels. The integrated regeneration mode enables rapid drying of the pump at the end of the process. This allows sample throughput to be increased significantly as compared to other pump technologies.
For work performed with non-corrosive gases and vapors, there is the specially designed model VACUU•PURE 10.

Screw pump for non-corrosive applications
The dry screw pump VACUU•PURE® 10 reliably delivers the benefits of oil-free vacuum technology in the pressure range down to 10-3 mbar. VACUU•PURE 10 combines three important benefits for the user: 100% oil-free, no abrasion, and no wear parts.
VACUU•PURE 10 is ideal for clean processes which require a dry and hydrocarbon-free vacuum. The spindles of the screw pump run contact-free and are thus free of abrasion and wear. The screw pump is especially designed for processes in the vacuum range down to 10-3 mbar, however unlike other fine vacuum technologies it can be used across the entire pressure range from atmospheric pressure to its ultimate vacuum. The evacuation of even larger systems from atmospheric pressure down to the 10-3 mbar vacuum range can be done without changing the vacuum pump.
VACUU•PURE easily handles high levels of vapor accumulation through its extraordinary condensate compatibility. Thanks to this capability, a gas ballast is unnecessary, avoiding associated disadvantages like the reduction in pumping speed and an increase in noise levels. The integrated regeneration mode enables rapid drying of the pump at the end of the process. This allows sample throughput to be increased significantly as compared to other pump technologies.
VACUU•PURE is also available in a chemically resistant design for working with aggressive gases and vapors.
