VACUUBRAND MZ 1C Chemistry Diaphragm Pump Ultimate Vacuum 12 mbar / 9 torr Maximum Pumping Speed 0.5 (more) cfm at 60Hz Number of Heads/Stages 2/2 Features - Outstanding chemical resistance and superior vapor tolerance. - Convenient, quick and simple to use due to the top mounted power switch. - Optimized vacuum even with gas ballast for continuous purge. - Whisper quiet and very low vibration. - Maintenance-free drive system and proven long diaphragm life. Chemistry-design diaphragm pumps are an excellent solution for continuous, oil-free pumping of corrosive gases and vapors. The two-stage construction provides the advantageous combination of high pumping speed and low ultimate vacuum. All major parts in contact with pumped media are made of chemically resistant fluoroplastics. Well-proven PTFE-sandwich diaphragms increase reliability and extend operating life. The MZ 1C pump is equipped with a gas ballast valve for continuous condensate purge increasing the pumping capability of condensable vapors. It features slim design for space-saving installation and good vacuum performance. A manual vacuum regulator valve with dial gauge for adjustment of pumping speed and ultimate vacuum is available as accessory. Two-stage chemistry-design diaphragm pumps are an excellent choice for continuous, oil-free pumping of gases at medium vacuum requirements. In contrast to water jet pumps, they do not consume water and therefore do not produce any contaminated waste water. Typical applications are rotary evaporators, gel dryers, filtrations and many other lab applications. The MZ 1C is a powerful pump for smaller vacuum apparatus enabling continuous pumping of solvent vapors. It´s a compact, stand alone pump with low ultimate vacuum. If the process requires atmospheric condensation of pumped vapors or electronic vacuum control, we recommend the pump families based on the MZ 2C NT or MD 1C. INCLUDED: The VACUUBRAND MZ 1C Chemistry Diaphragm Pump includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty

Edwards XDS35iC Dry Scroll Pump Ultimate Vacuum 1 x 10-2 mbar Inlet Connection NW40 Displacement 43  (more)m3h-1 / 25 ft3min-1 Features - High ultimate vacuum and rapid pumping speed ensure efficient operation across a wide range of laboratory and industrial applications - Quiet operation provides a comfortable working environment, reducing noise in sensitive areas - Features a pressurized oil system that lubricates pump shaft bearings and rotor sealing faces for reliable performance - Maintenance is simplified with an oil sight-glass for easy monitoring of oil levels and conditions at a glance - Facilitates easy oil changes with an oil drain plug that allows either gravity or pressure oil drainage for convenience - Compact, freestanding design allows flexible use without the need for additional support structures - Ideal for use with analytical instruments, leak detectors, helium research, and for backing turbomolecular pumps, showcasing its versatility Scroll pumps are an excellent alternative to rotary vane pumps where oil free pumping is desirable. The XDS pumps in particular use an innovative bearing shield to isolate the vacuum environment from all forms of lubricant not only making them totally dry, but also protecting the bearing from any process gases. Vapour handling is enabled by an adjustable gas ballast; this allows the range of pumps to satisfy many applications that were previously off limits to other scroll pumps. The Edwards XDS35iC features Chemraz internal valves and stainlesssteel fittings for extra protection from the pumped media. The ‘C’ series isbetter designed for more aggressive applications as opposed to the standardseries.
