Mini Diaphragm Vacuum Pumps LABOPORT® N 938.50 KT.18

The Pump combines a high flow rate with a very compact design. Suitable for filtration, SPE, and liquid aspiration using a vacuum. Due to the manual rotational speed control, the pump is quiet, very energy efficient, and can be optimally adjusted in accordance with the application.Easy-to-clean surfaceVery small footprintAdjustable in flowrate due to manual rotational speed controlPTFE-coated diaphragm for use with aggressive/corrosive gases and vapors

For filtration, degassing desiccation, liquid extraction and solid phase extraction.PTFE-coated diaphragm is ideal for aggressive/corrosive gases and vaporsPump head made from PPS (Polyphenylsulfide), valves made from FFPM (Perfluoro rubber)

Application: Fluid aspiration, Degassing, Gel drying, Rotary evaporation, Centrifugal concentration, DistillationHigh level of vapor and condensate compatibilityPTFE pump head combined with PTFE-coated diaphragm are ideal for extremely aggressive/corrosive gases and vaporsIn accordance with ATEX II 2/-G IIB+H2 T3 Gb internal atmosphere only

ATEX chemistry diaphragm pumps offer all advantages of oil-free chemistry diaphragm pumps. Typical applications are rotary evaporators and drying ovens with potentially explosive atmospheres. The ATEX approval includes the interior of the pump (in contact with pumped gases) as well as the surrounding area of the pump.Outstanding chemical resistance and superior vapor toleranceMainly made of antistatic materialsFlame proof motor with integrated, self-locking overload and excess temperature protection for direct 230V / 50Hz single phase power supplyOverpressure safety relief valves internally and at outletWith separate gas ballast connection part for use of inert gasSafety diaphragm technology with option for inert gas purge and detection of diaphragm breakageATEX compliance:Pump chamber (pumped gases): II 2G IIC T3 XExterior space (pump environment): II 2G IIB T4 X (with inert gas purging) / II 3G IIB T4 X (without inert gas purging)Speed-controlled ATEX VARIO vacuum pumps on request.

The diaphragm pumps ME 1C offer a compact and high performance solution. With their easy-to-use functionality, they are the perfect partner for both single and multiple filtrations.One-stage diaphragm pumps are an excellent solution for continuous, oil-free pumping of gases and vapors for modest vacuum requirements. In contrast to water-jet pumps, they do not consume water and therefore do not produce any contaminated waste water in daily use.Vacuum filtration is frequently used for sample preparation in chemistry, microbiology, waste water control and analysis.In the chemistry diaphragm pumps ("C") all major parts in contact with pumped media are made of chemically resistant fluoroplastics. The ME 1C is also often used for solid phase extraction (SPE).An optional manual regulator valve with dial gauge enables variable fine adjustment of the pumping speed and the ultimate vacuum.Gas ballast for reliable pump performance.Two up to four stage chemistry diaphragm pumps (letters in the product name Z, D or V) are equipped with a manual gas ballast valve as standard. The supply of gas ballast minimizes the risk of condensation inside the pump.The diaphragm pumps ME 1C offer a compact and high performance solution.
