VACUUBRAND ME 4 NT Diaphragm Pump Ultimate Vacuum 70 mbar (52 Torr) Maximum Pumping Speed 2.6 CFM a (more)t 60Hz Number of Heads/Stages 2/1 Features - Contamination-free pumping and evacuation - High flow rate even near ultimate vacuum - Whisper quiet - ME 4 NT with low vibration and higher pumping speed - Exceptionally long diaphragm life and maintenance-free drive system for low lifetime costs Diaphragm pumps are an excellent solution for continuous, oil-free evacuation and pumping of gases. All parts in contact with pumped media are made of aluminum and selected plastics, allowing a wide range of applications for non-corrosive gases. The one-stage construction provides the advantageous combination of high pumping speed and an ultimate vacuum down to 70 mbar. The highly flexible fabric-reinforced double diaphragm made of FKM is ideal for extended operating life. The NT-series features further improved performance data. One-stage diaphragm pumps are an excellent choice for continuous, oil-free pumping at modest vacuum requirements. In contrast to water jet pumps, they do not consume water and therefore do not produce any contaminated waste water. Typical applications are vacuum ovens, aqueous filtrations and pumping and evacuation of non-aggressive gases in general. The ME 4 NT offers shorter evacuation times and higher gas throughput.INCLUDED: The VACUUBRAND ME 4 NT Diaphragm Pump includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty

The KNF N860.3FT.40.18 IP54-T Diaphragm Pump can be used veryuniversally due to its high resistance to aggressive media. The KNFself-drying system allows condensed liquid to be blown out of the pump heads ata high speed during evacuation. The drying cycle can be adjusted to therequirements of the individual process using three variables. The KNFN860.3FT.40.18 IP54-T Diaphragm Pump is chemical-resistant, therefore suitable forhighly aggressive or corrosive gasses and vapors.INCLUDED: The KNF N860.3FT.40.18 IP54-T Diaphragm Pump includes: - Power Cord - Operator's Guide - Manufacturer's Documentation - 1 Year Manufacturer's Warranty

KNF IP65 FEM 1.02 KT.18RCP Liquid Pump KNF SIMDOS diaphragm pumps offer a variety of options to suit (more) most laboratory liquid metering and dosing needs. The FEM 1.02 KT.18RCP version has a liquid transfer flow rate of 0.03 – 200 mL/min and discreet dosing volumes of 0.03 – 999 mL. It is constructed with the following chemically-resistant flow path materials: polypropylene head, PTFE covered diaphragm, and FFKM valves. The easy-to-read display combined with a touch control knob makes programming and access of all functions very intuitive. Besides onboard manual control, this pump offers analog control, start/stop and reset/prime TTL logic control, output signal fault alarm, and RS 232 PC control. A RC control interface cable and RS 232 cable with D-Sub 9 connector are included. A foot switch for start and stop impulses is available. All SIMDOS pumps are simple and intuitive to operate, compact, and quiet, making them a welcome addition to any business or academic lab. They are effective against pressures of up to 85 psig and transfer viscous media up to 500 centistokes (reduced flow rate above 150 cSt). The integrated software permits the transfer parameters to be modified for a range of different viscosities at the touch of a button. With a durable and IP65 splash-proof design, these pumps are maintenance free, and provide trouble-free ±2% accuracy and ±1% repeatability performance. SIMDOS 02 pumps are self-priming up to 6.6 feet of water, and can run dry indefinitely without damage. Also, unlike peristaltic pumps, there are no troublesome tubing to break or fatigue. INCLUDED: The KNF IP65 FEM 1.02 KT.18RCP Liquid Pump includes: - Power Cord - Operator's Guide - Manufacturer's Documentation - 1 Year Manufacturer's Warranty

Varioshake shaking incubator These LAUDA tools are renowned for being extremely reliable and suitabl (more)e for heavy use. Specialized in gentle mixing and vigorous shaking, these shaking incubators are used for applications that require repeatable orbital movements and temperatures up to +70°C with excellent stability. They are preferred by standard or research laboratories for incubation, fermentation, homogenization, chemical and biochemical reactions, enzyme and tissue studies, as well as for the cultivation of bacterial cultures. Applications: homogenization, incubation, fermentation or chemical and biochemical reactions. The control panel features soft-touch keys with clear symbols. It will therefore be very easy to set the temperature, the stirring frequency or the incubation time quickly and precisely, rest assured that the technology of these instruments will exactly reproduce the set values. The temperature - Temperature regulation is controlled by a microprocessor, PID type with RS232 interface. - The temperature distribution is optimal throughout the interior of the cabinet. - Temperature setting and display: digital, LED, in 0.1°C increments. - Temperature range: from 8°C above ambient temperature to +70°C. - Temperature range (with cooling coil; not included): 20 to 70°C, depending on the cooling medium used and the ambient temperature. - Electronic monitoring of the temperature controllers activates visual and acoustic alarms in the event of a fault. In these cases the heating switches off automatically and the cause of the anomaly is shown on the display. Agitation and Incubation - Quiet and robust stirring mechanism with gentle start and smooth, load-independent orbital motion - The orbital motion can be turned on and off - Shaking frequency and incubation time can be set thanks to the microprocessor. - The timer continuously displays the remaining incubation time and acoustically signals its expiration.
