KNF IP65 FEM 1.02 ST.18RCP Liquid PumpKNF SIMDOS diaphragm pumps offer a variety of options to suit  (more)most laboratory liquid metering and dosing needs. The FEM 1.02 ST.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: stainless steel 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 ST.18RCP Liquid Pump includes: - Power Cord - Operator's Guide - Manufacturer's Documentation - 1 Year Manufacturer's Warranty

Heidolph Rotavac Valve Tec Ultimate Vacuum 12 mbar Suction Capacity 0.75 m³/h Nominal Rotation Spee (more)d 1,800 RPM Features - Recommended for solvents with low or medium boiling points - Vacuum can be controlled through valves or manual vacuum controllers - A vacuum valve is necessary if you wish to combine this vacuum pump with Hei-VAP Expert Control/Ultimate Control rotary evaporators All components that come in contact with media are made from chemically resistant fluoropolymer.
