• The vacuum system consists of central vacuum pumps and a pipe system for distributing the vacuum. 
• The system replaces local vacuum pumps for some applications, thus saving space and reducing noise in the laboratories.

• The vacuum in the system is between 8 and 22 millibar, (33/liters per minute per valve), and thus it can replace membrane pumps and water jet pumps.
• If you need a stronger vacuum, you still need to use oil or scroll pumps able to deliver vacuum above 0.05 millibar.
• Typical applications are suction filtration and rotary evaporators.
• The system is switched on Monday till Friday from 07:00-20:00. It is closed down during weekends.

• The setup is connected to the fitting, and the valve is opened.
• If there is any risk that fluids may be sucked into the vacuum system, you have to use a safety flask on the hose.

• The vacuum pumps and the piping are chemical resistant, but it is NOT allowed to use the system to dispose of hazardous substances or liquids.
• As several people will share the same vacuum, you must remember to close the valve as soon as the suction filtration is complete.
