Laboratory pumps

Laboratory pumping systems are used to transfer volumes of fluids and gases. Vacuum pumps are used in chemistry labs for filtration or decreasing the pressure in drying or evaporation and distillation processes. Syringe pumps and peristaltic pumps are frequently used to accurately transfer liquids, e.g. through a microfluidics system.

VACUUBRAND MD 12 NT Diaphragm Pump-cover
VACUUBRAND MD 12 NT Diaphragm Pump

VACUUBRAND MD 12 NT Diaphragm Pump Ultimate Vacuum 2 mbar (1.5 Torr) Maximum Pumping Speed 7.1 CFM  (more)at 60Hz Number of Heads/Stages 8/3 Features - Contamination-free pumping and evacuation - High flow rate even near ultimate vacuum - Whisper quiet - Reduced process times - Exceptionally long diaphragm life and maintenance-free drive system for low lifetime costs The MD 12 NT diaphragm pump is an especially powerful pump for oil-free evacuation and pumping of non-aggressive gases. The three-stage design of this eight-cylinder pump provides the advantageous combination of very high pumping speed and excellent ultimate vacuum. The flow path consists of aluminum, stainless steel and carefully selected plastics to permit a wide range of applications. The fabric-reinforced double diaphragms are made of highly flexible FKM for extended operating life and high vacuum performance. Eight-cylinder NT pumps feature quiet operation, with smooth and easy-to-clean surfaces. Like all VACUUBRAND diaphragm pumps they operate absolutely oil-free and do not have any sliding components in the gas path. In normal operation they are completely free of abrasion. This eliminates most of the particulate impurities frequently generated inside of scroll or piston pumps. The MD 12 NT is an excellent choice for continuous, oil-free evacuation and pumping of non-aggressive gases, especially for applications in physics and analytics. Due to the very good ultimate vacuum the MD 12 NT is often used as an alternative to rotary vane pumps, for example for vacuum ovens, for very quick and efficient degassing of viscous media, exhaust gas analytics and especially as backing pump for large turbomolecular drag pumps. The particularly high pumping speed enables the usage of bigger vacuum apparatus and with high gas throughput. The pump is extraordinarily silent and exhibits very low vibration making it an excellent choice for sensitive equipment such as electron microscopes. Back diffusion of oil or even oil back flow, e.g., into a high vacuum chamber is excluded due to its oil-free operation. INCLUDED: The VACUUBRAND MD 12 NT Diaphragm Pump includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty

VACUUBRAND MD 1 Diaphragm Pump-cover
VACUUBRAND MD 1 Diaphragm Pump

VACUUBRAND MD 1 Diaphragm Pump Ultimate Vacuum 1.5 mbar (1.1 Torr) Maximum Pumping Speed 0.82 CFM a (more)t 60Hz Number of Heads/Stages 4/3 Features - Contamination-free pumping and evacuation - High flow rate even near ultimate vacuum - Excellent ultimate vacuum - Whisper quiet and ultra-low vibration - Proven long diaphragm life, maintenance-free drive system The MD 1 diaphragm pump is an excellent choice for oil-free evacuation and pumping of non-corrosive gases down to 1.5 mbar ultimate vacuum. The three-stage design with precisely guided flat diaphragms provides outstanding pumping speed even close to the ultimate vacuum, especially when compared with similarly rated two-stage diaphragm pumps. The MD 1 is an ultra-low vibration pump with very long diaphragm lilfetime and stable ultimate vacuum documented with years of testing. With a flow path consisting of aluminum and selected plastics (diaphragms and valves made of PTFE/FKM and FKM, respectively) the pumps are suitable for a wide range of applications with non-corrosive gases. The MD 1 is an excellent choice for continuous, oil-free evacuation and pumping of non-aggressive gases. It is suitable for high vacuum requirements at modest gas flow as often needed in physics and analytics. The pump is exceptionally quiet and reliable with long diaphragm and valve lifetimes. With its low ultimate vacuum and compact dimensions the MD 1 is widely used as replacement of rotary vane pumps. Typical applications are exhaust gas analysis, for degassing of small amounts of viscous media and in particular as backing pump for compact turbomolecular drag pumps. Back diffusion of oil or even oil back flow, e.g., into a high vacuum chamber is excluded due to its oil-free operation. For equipment manufacturers customized versions are available.INCLUDED: The VACUUBRAND MD 1 Diaphragm Pump includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty
