Beskrivelse: Chemistry diaphragm pumps of the NT design are an excellent solution for continuous, oil-free pumping of corrosive gases and vapors. The one-stage construction provides the advantageous combination of high pumping speed and low ultimate vacuum down to 70 mbar. All major parts in contact with pumped media are made of chemically resistant fluoroplastics. Well-proven PTFE sandwich diaphragms for increased reliability and extended operating life. The eight cylinders pump ME 16C NT provides a particularly high performance together with a compact design. Upgraded with an outlet exhaust vapor condenser (EK) the ME 16C NT +EK provides an environmental friendly system with efficient solvent recovery. Eight-cylinder NT pumps feature quiet operation, smooth and easy to clean surfaces.

Beskrivelse: Modeller PD 5201 og PD 5206 til avancerede krav. Peristaltiske pumper er ideelle til transport og udmåling af aggressive, slibende eller ætsende opløsninger og kan også bruges til sterile medier under lavt tryk. Mediet, som skal flyttes, kommer kun i kontakt med slangen, og der forekommer derfor ikke kontaminering. Velegnet til transport af meget viskøse medier op til 10.000 mPas. Pumperne er selvsugende uden forseglinger eller ventiler. De kan bruges til filtrering og separering i fødevareindustrien. i bioteknologi, til vandrensning og til alm. laboratorieopgaver. Medier kan transporteres under tryk og under vakuum. Vedligeholdelsesfrie motorer sikrer en lang levetid. De af pumpehovederne angivne mængder gemmes i programmet alt efter den brugte rørtype og vises i det digitale display. Software kan bestilles separat som tilbehør. Pumpedrevet styres af en mikroprocessor. Udstyret med digitalt RS232 interface: hastighed, udmålt mængde, flowhastighed, pause og rørdimension kan styres. Digital visning af hastighed (min⁻¹) og flowhastighed (ml/min). Digital visning af volumenfortrængning (ml) i tilfælde med volumendosering. Periodisk udmåling er mulig med justerbare pausetidspunkter. Et udmålt volumen kan også specificeres sammen med flowhastighedsvisningen. Meget simpel kalibrering af volumenfortrængning (ml) og flowhastighed (ml/min).

Beskrivelse: The VacuuCenter BVC basic is designed for connection to an existing external vacuum source like a diaphragm pump or a vacuum network (e.g., VACUU·LAN®) and does not require electric power. The chemically resistant mechanical vacuum controller always ensures an optimal operating vacuum. The controller opens only when needed thus limiting the gas load on the vacuum source. The evaporation of collected liquid is minimised. The inlet tubing integrated in the bottle head reduces aerosol and foam formation and ensures a long service life of the hydrophobic protection filter. The aspiration system is available either as BVC basic with 4 litre PP bottle or as BVC basic G with 2 litre coated borosilicate glass bottle.

Beskrivelse: The VacuuCenter BVC control serves for efficient and convenient aspiration of supernatants. The vacuum level - and thus the suction force - is precisely adjustable via the electronic touch panel and allows a sensitive and reproducible operation. The chemically resistant diaphragm vacuum pump is automatically turned on and off as needed, which reduces the low noise level even further. The BVC control is available in two complete equipment options with different collection flasks. The 2 litre borosilicate glass bottle with a protective coating has a very high chemical resistance. For larger amounts of liquids the 4 litre bottle of unbreakable polypropylene (PP) is used. The smooth surfaces allow an easy cleaning of the systems.

Beskrivelse: The VacuuCenter BVC professional serves for aspiration and disposal of biological fluids, providing outstanding levels of comfort and safety for working with biological and biohazardous materials. A non-contact sensor monitors the liquid level in the collection bottle electronically and prevents overfilling. A disinfection routine allows the suction of disinfectants through an aspiration hand set and tubing after switching off the pump, and so supports demanding safety protocols. The BVC professional with 4 litre PP bottle with self-closing quick couplings minimises risk in transporting hazardous waste and of contamination in the workplace. The version with coated 2 litre borosilicate glass bottle allows the user to work with aggressive disinfectants like chlorine bleach.
