Chemglass CG-4812-10 Vacuum Pump, 17L/min, 50 Torr, 115V, 60Hz

Features:

• Oil-Free Operation: Pumps eliminate the disposal problem of contaminated oil.
• Maintenance Free: Pumps are equipped with oversized, long life, permanently lubricated ball bearings. Heads are easily disassembled without special tools for periodic cleaning.
• Consistent Performance: Unlike water aspirators which depend on water temperature and pressure, these pumps always deliver consistent, dependable performance without using precious water resources or polluting waste drains.
• Contamination-Free Transfer: Due to the fact that these pumps do not use oil, your pumped medium never comes in contact with oil or grease and always stays analytically pure.

Applications:

• Rotary Evaporation and Distillation Low to Medium BP Solvents (35-80°C)
• Vacuum Drying
• Solvent Recovery Systems
• Transfer of Corrosive Gases
• Vacuum Concentration
• Vacuum Filtration
• Degassing of Liquids 

The Chemglass series of all PTFE vacuum pumps are an excellent source of vacuum in the laboratory. They eliminate the concern about the chemical attack on the pump or contamination of your pumped medium. Solid PTFE heads do not blister or peel, and advanced Kalrez® valves along with unique PTFE coated, molded structure diaphragm provide the longest possible lifetime when pumping corrosive gases. They are perfect for use in rotary evaporation, vacuum distillation, vacuum filtration, gel drying, or the transfer of corrosive gases. Using no house air or water for its operation, it conserves valuable resources and helps protect the environment by eliminating the disposal of solvent-contaminated wastewater or oil.
