Oil-Free Chemistry Diaphragm Pump

VACUUBRAND Oil-free Chemistry Diaphragm Vacuum Pumps are designed for excellent corrosion resistance in routine biology and chemistry lab applications.Features:Excellent Corrosion Resistance. VACUUBRAND Oil-free Chemistry Diaphragm Vacuum Pumps are constructed of materials with excellent corrosion resistance, such as PTFE heads and diaphragms. All multistage pumps are equipped with a gas ballast to provide consistent pump performance with condensed vapors.No Oil Changes. These vacuum pumps utilize diaphragm vacuum technology. The totally dry operation eliminates the misting, handling and disposal of contaminated waste associated with rotary vane pumps. No oil to change or monitor!Reduced Maintenance. Typical diaphragm lifetimes are well in excess of 15,000 hours of use before replacement - that's years in most applications, minimizing downtime and service costs. When it is finally time for service, their unique design eliminates tedious, trial-and-error stroke length recalibration.Improved Productivity. VACUUBRAND pumps are engineered for performance, with flow rates as much as 40% higher at working vacuum level than competitive pumps with similar free air capacity ratings. Higher flow rates mean reduced process times and higher throughput.Quiet & Reliable. VACUUBRAND pumps offer whisper-quiet operation and low vibration. Plus, all VACUUBRAND pumps and systems must pass rigorous product testing before leaving the factory. It's your assurance of a reliable pump.
