VACUUBRAND MD 4 VARIO Select Diaphragm Pump Ultimate Vacuum 1 mbar (0.75 Torr) Maximum Pumping Spee (more)d 3.4 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 - Extraordinary diaphragm life for minimum operational and servicing costs - Contamination-free pumping and evacuation - Excellent ultimate vacuum and TURBO-MODE for use as backing pump for turbo pumps This three-stage diaphragm pump is an excellent solution for continuous, oil-free pumping of non-corrosive gases to a vacuum level as deep as 1 mbar. All wetted parts are made of aluminum, stainless steel and carefully selected plastics suitable for a wide range of applications with non-corrosive gases. The MD 4 VARIO select continuously adapts its motor speed to hold the desired vacuum level. That means the pump is whisper-quiet and generates ultra-low vibrations and has high leak tightness. The highly flexible fabric reinforced double FKM diaphragm is ideal for extended operating life. The VARIO design includes the variable speed pump and the VACUU·SELECT vacuum controller with external gauge head. The demand-responsive motor speed control on VARIO models further extends the already long lifetimes of diaphragms and valves. These three-stage diaphragm pumps are an excellent choice for continuous, contamination-free evacuation and pumping of non-aggressive gases at demanding vacuum conditions. They are especially suitable for applications requiring high volume flow in physics and analytics. The low ultimate vacuum makes these an attractive alternative to rotary vane pumps. Typical uses are as backing (roughing) pumps for turbomolecular drag pumps, for degassing of viscous media, as well as for exhaust gas analytics. Additionally, the VARIO model provides vacuum control by precise adjustment of the diaphragm pump´s motor speed to process requirements. 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. Depending on the application, the demand-responsive motor speed control of VARIO models further extends the long diaphragm life for which VACUUBRAND pumps are well-known. In addition, it provides an even higher pumping speed and enables precise vacuum control. INCLUDED: The VACUUBRAND MD 4 VARIO Select Diaphragm Pump includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty

E1-class mass standards are the elite in the world of metrology, because standards of this class rep (more)resent the highest level of precision and accuracy in mass measurement. The E1 classification is one of the most stringent standards that standards must meet in order to be considered the most advanced and trustworthy measurement tools. E1 - class standard: stainless steel wire Nominal value: 500 mg Material: stainless steel What Are the Characteristics of the E1 Class? Highest Precision - The allowable deviation from the actual weight is minimal, making standards of this class ideal for applications where every gram matters. Stability and Repeatability - This guarantees a consistent level of accuracy over the long term. Accurate Calibration - Standards of this class must be regularly compared with other standards of known mass to confirm their measurement accuracy. Materials with Unique Properties - E1 class mass standards are often made of materials with exceptional physical properties, which makes them stable and resistant to changes in environmental conditions. Application 1. Analytical Laboratories In analytical laboratories where accurate measurements are crucial, E1 class mass standards are used to calibrate balances with the highest precision. 2. Pharmaceutical Industry In drug manufacturing, where even the slightest deviation from the standard affects quality, E1 class mass standards are irreplaceable. 3. Scientific Research In scientific research, especially in areas requiring the highest precision, such as physics or chemistry, E1 class mass standards are used to ensure reliable results. 4. Metrology Industry In metrology laboratories where research on E1 class mass standards alone is carried out, E1 class standards are the standard of excellence. Class E1 mass standards are not only measuring tools, but also a symbol of metrological excellence. Their use affects the quality of measurements in various areas of life because they provide precision that can be relied upon. They are a key element in the world of mass measurement, shaping standards and raising the bar for all measurement tools.
