VACUUBRAND ME 2C NT Chemistry Diaphragm Pump

VACUUBRAND MV 2 VARIO Select Diaphragm Pump Ultimate Vacuum 0.3 mbar (0.2 Torr) Maximum Pumping Spe (more)ed 1.9 CFM at 60Hz Number of Heads/Stages 4/4 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 - Contamination-free pumping and evacuation - Excellent ultimate vacuum, and even better ultimate vacuum with VARIO version in TURBO-MODE for use as backing pump for turbo pumps Four-stage diaphragm pumps - like the MV 2 VARIO select - are an excellent solution for continuous, oil-free pumping of non-corrosive gases at fractional millibar vacuum levels. Wetted parts are made of aluminum, stainless steel and carefully selected plastics suitable for a wide range of non-corrosive applications. The MV 2 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 an external gauge head. The demand-responsive motor speed control on VARIO models further extends the already long lifetimes of diaphragms and valves. Four-stage diaphragm pumps are an excellent choice for continuous, contamination-free evacuation and pumping of non-aggressive gases under the very high vacuum demands of applications in physics and analytics. They generate a clean vacuum as they are designed without any sliding seals. Hence abrasion or dust are excluded that might creep back into the application. Due to the outstanding ultimate vacuum these pumps are often used as an alternative to rotary vane pumps. A typical application is the use as backing pump for turbomolecular drag pumps. Additionally, the VARIO version provides vacuum control by precise adjustment of the diaphragm pump's motor speed. Depending on the application the demand-responsive motor speed control results in unsurpassed lifetimes of service parts like diaphragms as well as optimal performance for backing of turbo pumps. INCLUDED: The VACUUBRAND MV 2 VARIO Select Diaphragm Pump includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty

FibraStage is an inexpensive, labor-saving and disposable cell culture system capable of producing p (more)roteins, viruses or cell mass from anchorage-dependent and suspension cultures. The system uses 500 mL disposable bottles pre-filled with FibraCel disks, a unique solid-support matrix for cell growth. FibraCel provides a low-shear environment and extremely high surface area (100 cm²) for cell growth, equivalent to dozens or even hundreds of T-flasks and roller bottles. Each FibraStage system holds up to four bottles, capable of yielding 2 x 10¹⁰ cells. Oxygenation and media mixing are simply and effectively accomplished by placing the bottles in the FibraStage device, which collapses bellows at the base of each bottle forcing media up through the disk bed. Cells remain entrapped in the disk bed during the entire run, simplifying media replacement and product recovery. The system eliminates autoclaving, cleaning, lengthy learning curves, costly start-up, and cross-contamination issues between batches, and requires only a standard CO₂ incubator.
