VACUUBRAND ME 1C Chemistry Diaphragm Pump Ultimate Vacuum 100 mbar / 75 torr Maximum Pumping Speed 0 (more).5 CFM at 60Hz Number of Heads/Stages 1/1 Features - Convenient, quick and simple to use due to the new top-mounted power switch. - Whisper quiet and very low vibration. - Requires minimal benchtop space. - Maintenance-free drive system and proven long diaphragm life. - High chemical resistance. Vacuum filtration is one of the most common applications used for sample preparation in chemistry, microbiology, waste water control and other analytical processes. The ME 1C diaphragm pump offers a compact, high performance and easy-to-use solution which is perfect for single filtrations. This development, based on the highly successful technology of the oil-free diaphragm pump MD 1C, provides a well-proven and extraordinarily long diaphragm life time. The functional, space saving and innovative design with easily accessible, top-mounted power switch ensures convenient and quick operation for day-to-day lab work. Robust PTFE diaphragms and valves provide optimal chemical resistance. A manual vacuum regulator valve with dial gauge for adjustment of pumping speed and ultimate vacuum is available as accessory. One-stage diaphragm pumps are an excellent solution for continuous, oil-free pumping of gases and vapors with a modest vacuum requirement. In contrast to water-jet pumps they do not consume water and therefore do not produce any contaminated waste water in daily use. Typical applications for the ME 1C are filtrations and solid phase extractions with solvents. At a process vacuum of 100 mbar, 90% of the atmospheric pressure is available as the driving force for the application. If a certain pressure difference must not be exceeded, the pump can be equipped with an optional manual vacuum regulator valve with dial gauge. It enables continuous adjustment of pumping speed and ultimate vacuum. INCLUDED: The VACUUBRAND ME 1C Chemistry Diaphragm Pump includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty

VACUUBRAND MD 4C VARIO Select Chemistry Diaphragm Pump Ultimate Vacuum 1.5 mbar (1.1 Torr) Maximum  (more)Pumping Speed 2.7 CFM at 60Hz Number of Heads/Stages 4/3 Features - VACUU-SELECT vacuum controller with graphical user interface and predefined applications simplifies work in the laboratory - Automatic boiling point detection and adjustment of the vacuum for short process times - Extraordinary diaphragm life for minimum operational and servicing costs - Meets high vacuum requirements for most high boiling solvents The MD 4C VARIO select pump is an excellent solution for labs working with most high boiling point solvents. The pump's three stage configuration gives it an ultimate vacuum rating of 1.5 mbar. The integrated VACUU-SELECT controller provides an easy-to-use, application-based interface that covers all common lab applications. The VACUU-SELECT controller has you covered. Use manual set-point-control for simple processes, run fully automated distillations, or create your own application with simple drag-and-drop editing. For solvent evaporation, the VACUU-SELECT controller continuously detects the boiling point and automatically adjusts the vacuum process as necessary. VARIO's on-demand motor speed control results in whisper-quiet operation and unparalleled length of service intervals for wear parts. Typical applications are all evaporation processes. They can be run fully automatically and with shorter process times and extra sensitivity even for challenging mixtures at the same time. The VARIO® control ensures high process reliability through prevention of boiling retardation or foaming. It detects boiling pressures automatically and self-adapts to changing process parameters at any time. This is all without any need for parameter input or the use of a solvent library. Also, in many other applications and in laboratory vacuum networks the VARIO control brings significant advantages as it always provides the appropriate pumping speed. The VACUU-BUS interface facilitates a user-friendly configuration of even complex vacuum installations. INCLUDED: The VACUUBRAND MD 4C VARIO Select Chemistry Diaphragm Pump includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty
