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

Stainless steel platform scale with four sensors No matter where you place the load on the platform, (more) the result will always be correct. This is due to the four sensors built into the platform. You will appreciate this especially when weighing an irregularly shaped object. It has been with us for years, and will stay for a long time to come The LCD display has accompanied us for long years. During this time it has proven its reliability. It guarantees the readability of the result from many angles and is energy efficient. Inner power No access to mains power? Power failure? No problem. Thanks to its internal rechargeable battery, the H315 scale works anyway (up to 7 hours). Power supply is available at an extra charge. As standard, the scale is equipped with a RS232 cable, to which you can connect most of the accessories from our range. Not just weighing But also parts counting, percent weighing, animal weighing and peak hold. The power of H315’s working mods. Do you require fast and repeatable weight measurement under difficult conditions? The H315 scale is made for that! Work as you like The PUE H315 terminal sits on a 3-meter cable that allows you to hang the terminal on the wall. This allows you to arrange your weighing workplace in many ways. The power of steel The use of stainless steel guarantees you a long life for the scale. It is not afraid of contact with moist objects or accidental splashes. The membrane keyboard is another argument in the discussion of the water resistance of this scale. If you need a dual-range scale, we can make one for you at an extra cost.
